BACKGROUND: Large language models including GPT-4 (OpenAI) have opened new avenues in health care and qualitative research. Traditional qualitative methods are time-consuming and require expertise to capture nuance. Although large language models have demonstrated enhanced contextual understanding and inferencing compared with traditional natural language processing, their performance in qualitative analysis versus that of humans remains unexplored.
OBJECTIVE: We evaluated the effectiveness of GPT-4 versus human researchers in qualitative analysis of interviews with patients with adult-acquired buried penis (AABP).
METHODS: Qualitative data were obtained from semistructured interviews with 20 patients with AABP. Human analysis involved a structured 3-stage process-initial observations, line-by-line coding, and consensus discussions to refine themes. In contrast, artificial intelligence (AI) analysis with GPT-4 underwent two phases: (1) a naïve phase, where GPT-4 outputs were independently evaluated by a blinded reviewer to identify themes and subthemes and (2) a comparison phase, where AI-generated themes were compared with human-identified themes to assess agreement. We used a general qualitative description approach.
RESULTS: The study population (N=20) comprised predominantly White (17/20, 85%), married (12/20, 60%), heterosexual (19/20, 95%) men, with a mean age of 58.8 years and BMI of 41.1 kg/m2. Human qualitative analysis identified \"urinary issues\" in 95% (19/20) and GPT-4 in 75% (15/20) of interviews, with the subtheme \"spray or stream\" noted in 60% (12/20) and 35% (7/20), respectively. \"Sexual issues\" were prominent (19/20, 95% humans vs 16/20, 80% GPT-4), although humans identified a wider range of subthemes, including \"pain with sex or masturbation\" (7/20, 35%) and \"difficulty with sex or masturbation\" (4/20, 20%). Both analyses similarly highlighted \"mental health issues\" (11/20, 55%, both), although humans coded \"depression\" more frequently (10/20, 50% humans vs 4/20, 20% GPT-4). Humans frequently cited \"issues using public restrooms\" (12/20, 60%) as impacting social life, whereas GPT-4 emphasized \"struggles with romantic relationships\" (9/20, 45%). \"Hygiene issues\" were consistently recognized (14/20, 70% humans vs 13/20, 65% GPT-4). Humans uniquely identified \"contributing factors\" as a theme in all interviews. There was moderate agreement between human and GPT-4 coding (κ=0.401). Reliability assessments of GPT-4\'s analyses showed consistent coding for themes including \"body image struggles,\" \"chronic pain\" (10/10, 100%), and \"depression\" (9/10, 90%). Other themes like \"motivation for surgery\" and \"weight challenges\" were reliably coded (8/10, 80%), while less frequent themes were variably identified across multiple iterations.
CONCLUSIONS: Large language models including GPT-4 can effectively identify key themes in analyzing qualitative health care data, showing moderate agreement with human analysis. While human analysis provided a richer diversity of subthemes, the consistency of AI suggests its use as a complementary tool in qualitative research. With AI rapidly advancing, future studies should iterate analyses and circumvent token limitations by segmenting data, furthering the breadth and depth of large language model-driven qualitative analyses.

BACKGROUND: A buried penis (BP) is rare in which the penile body is retracted into the prepubic adipose tissue. This research focuses on differences in smooth muscle myosin heavy chain (SMMHC) isoform expressions in the dartos fascia.
METHODS: A total of 82 children, 41 of whom had BPs, who applied for circumcision between May and November 2021, were included in the study. The cases were divided into four groups aged ≥6 years (NP6, n = 18) and aged ≤3 years (NP3, n = 17) with normal penile appearance, aged ≥6 years (BP6, n = 23) and aged ≤3 years (BP,n = 24) with a BP. SMMHC isoforms mRNA gene expression analyses were performed by quantitative PCR technique in dartos fascia obtained from foreskin removed by circumcision.
RESULTS: Compared to the NP3 group, the SM1 mRNA expressed in the BP6 group was statistically significantly higher (p < 0.005). SM2 mRNA levels expressed in dartos fascia were considerably higher in NP6 and NP3 groups compared to BP6 and BP3 groups (p < 0.001). The SM2/SM1 ratio was 0.85 in the BP6 group and 1.46 in the NP6 group, which was statistically significant (p = 0.006) and increased from 0.87 in the BP3 group to 2.21 in the NP3 group (p < 0.001).
CONCLUSIONS: In a buried penis, there is a difference in the expression of SMMHC isoforms. SM1 is highly expressed, while SM2 decreases, increasing the SM2/SM1 ratio. This causes increased contractility in the smooth muscle, leading to retraction of the penile body. The dartos fascia surrounding it resembles aberrant muscle tissue in boys with a BP.
METHODS: Level III.
METHODS: Case-control study.

This article provides a comprehensive discussion of 3-piece inflatable penile implant surgery when performed through an infrapubic approach in patients presenting with challenging anatomy or corporal fibrosis. The infrapubic approach is one of the primary approaches for inflatable device placement with excellent long-term functional outcomes. While the literature is rich in descriptions of infrapubic placement in the primary, uncomplicated setting, its role in the management of complex patients presenting to centers of excellence is less elucidated. In uncomplicated cases, the infrapubic approach offers several theoretical advantages including shorter operative time and quicker return to sexual function. In addition to describing specific details of our infrapubic technique and perioperative management, I discuss scenarios in which an infrapubic approach may allow for better exposure for correction of dorsal deformity, facilitate secondary surgical maneuvers such as suprapubic lipectomy, or protect existing incontinence prosthetics already in place. Specific technique and surgical pearls from our prosthetic center of excellence are reviewed for each of these challenging scenarios. Ultimately, prosthetic surgeons should be adept at placing, revising, and removing devices through both approaches so that various forms of anatomical deformity and device failures can be addressed proficiently. In addition to my own clinical reflections, a critical review was performed using the Medline database to support our statements.

UNASSIGNED: In the United States, acquired buried penis deformity is an increasingly more common condition. Management of the buried penis deformity is accomplished with removal of macerated skin and subcutaneous tissue from the panniculus and prepubic region, and replacement of denuded penile skin. If local tissue advancement is insufficient to cover the defect, a skin graft may be required. Though the anterior thigh is commonly used, this creates a second defect. Here we describe 2 cases of split-thickness skin grafts harvested from the panniculus to cover buried penis deformities.
UNASSIGNED: Two patients with a buried penis deformity were identified. The denuded suprapubic tissue was elevated. Using inferior traction, split-thickness skin grafts were harvested and placed onto the shaft of the penis. The remaining excess tissue was resected.
UNASSIGNED: One patient had a fungal rash that resolved with topical treatment. The other patient had a hematoma requiring surgical evacuation. Neither patient had any other complications, and both had over 95% take of the split-thickness skin grafts.
UNASSIGNED: These cases demonstrate the successful use of pannicular skin grafts for buried penis deformity correction. This donor site avoids creation of a second defect. As demonstrated here, the grafts are a durable option, even in the setting of local infection and hematoma.

OBJECTIVE: Adult acquired buried penis (AABP) is a morbid condition often necessitating surgical intervention. Accurate assessment of pre- and postoperative symptoms is crucial to understand how AABP impacts a patients\' quality of life, verify surgical effectiveness, and practice patient-centered care. There is no validated patient-reported outcome instrument specific for AABP evaluation. We undertook a comprehensive review of existing literature on patient-reported outcome instruments post-AABP surgery to highlight the importance of developing a specific tool.
METHODS: Following the preferred reporting items for systematic reviews and meta-analysis 2020 guidelines, we queried three databases using relevant keywords (e.g., \"buried penis repair\"). Inclusion criteria were studies that discussed surgical management of AABP with patient-reported outcomes. Pediatric and congenital cases were excluded. Information collected included study design, level of evidence, number of participants included in the study, etiology of buried penis, surgical technique, preoperative or postoperative patient-reported outcomes, and patient-reported outcome instrument used.
RESULTS: Initial query identified 998 records. After abstract screening and applying the inclusion or exclusion criteria, a total of 19 articles with 440 patients were included. Eight studies implemented patient-reported outcome instruments. The international index of erectile dysfunction-5 and Likert satisfaction scales were used most frequently. Although all instruments were validated, none were validated in the specific context of AABP surgical intervention.
CONCLUSIONS: There is considerable heterogeneity within the AABP literature regarding patient symptomatology, postoperative complications, patient-reported outcomes, and instruments used. The results of this study emphasize the need for a patient-reported outcome measure to examine the influence of AABP repair on patient satisfaction and health-related quality of life.

Given that patients with morbid obesity are predisposed to frailty, we sought to determine whether the 5-Factor Modified Frailty Index (mFI-5) predicts postoperative complications following surgery for adult-acquired buried penis, and secondarily, to compare the mFI-5 to body mass index (BMI) and American Society of Anesthesiologists (ASA) status as preoperative risk stratification measures.
We included all patients who underwent surgical management for adult-acquired buried penis at an academic Level I trauma center between 2015 and 2023. A manual chart review was performed to collect data on patient demographics, modified frailty index variables, intraoperative data, postoperative outcomes, and complications.
A total of 55 patients underwent surgical repair of adult-acquired buried penis, with 26 experiencing postoperative complications (47.3%). Univariable regression analyses revealed that the mFI-5 was a significant predictor of postoperative complications (odds ratio [OR] 3.40, 95% confidence interval [CI]: 1.56-7.42, p = .002), ongoing postoperative urinary problems (OR 2.03, 95% CI: 1.02-4.05, p = .045), patient dissatisfaction with outcomes (OR 3.29, 95% CI: 1.35-8.02, p = .009), and persistent postoperative symptoms (OR 2.42, 95% CI: 1.10-5.35, p = .029). There was no significant association between ASA classification and postoperative complications (OR 1.59, 95% CI:.544-4.63, p = .398). Multivariable analysis demonstrated that the mFI-5 was an independent predictor of postoperative complications (OR 5.34, 95% CI: 1.80-15.9, p = .003) when controlling for BMI and age.
The mFI-5 is an independent predictor of postoperative complications in patients undergoing surgical repair of adult-acquired buried penis. The simplicity of the index permits efficient preoperative risk stratification of adult-acquired buried penis patients and provides important counseling information that may not be reflected by age or BMI alone.

Morbid obesity is associated with a wide range of metabolic, infective, and organic disorders related to adipose tissue overload. While careful documentation of internal autopsy findings is usual, skin manifestations may be overlooked. Skin manifestations are quite diverse and include striae distensae, skin tags, plantar hyperkeratosis, acanthosis nigricans, the sequelae of hyperandrogenism, lymphedema, panniculus morbidus, chronic venous insufficiency, stasis dermatitis, leg ulceration, intertrigo, cellulitis, pressure ulcers and \'buried penis\'. Obesity has also been associated with hidradenitis suppurativa, psoriasis, atopic dermatitis, melanoma, systemic lupus erythematosus, lichen planus and acne vulgaris. Evaluating these findings at the time of autopsy may give a more complete assessment of a particular case and may also identify conditions that may have contributed to, or caused, death.

Penile length loss is often observed in patients with erectile dysfunction and obesity. In patients with a prominent infrapubic fat pad, the excess fat can further reduce perceived penile length.1 As others have reported, concurrent suprapubic lipectomy and placement of a penile implant has been shown to be an effective way of exposing phallic length in this challenging patient population.2,3 OBJECTIVE: In this video, we present surgical technique and initial outcomes of concurrent suprapubic lipectomy and 3-piece inflatable penile prosthesis (IPP) placement in patients that have erectile dysfunction and lipodystrophy of the mons pubis.
We retrospectively reviewed an institutional review board-approved prosthetic database of male patients that underwent placement of a 3-piece IPP and concurrent suprapubic lipectomy from 2020 to 2023. Intraoperative complications and postoperative outcomes were collated and analyzed. To perform this operation, an elliptical incision is made around the suprapubic fat pad that extends to the base of the penis inferiorly. Laterally the incision is carried just medial to the inferior margin of the iliac crest. Sharp dissection and electrocautery are used to dissect the fat pad free. A layer of areolar tissue is preserved above the layer of the fascia to prevent seroma formation. For larger blood vessels, vascular clips are used to ensure adequate hemostasis. After removal of the fat pad, placement of the penile prosthesis can proceed as one would through an infrapubic approach. After the device is placed, the tissue flaps based on the external pudendal vessels are inspected for adequate vascularity. Penetrating towel clamps are used to approximate the skin edges from lateral to medial so that the midline closure can be approximated accurately. 0-PDS is used to anchor the flap superiorly into the lower edge of the abdominal fold. The incision is then closed in multiple layers of absorbable suture from lateral to medial. A skin stapler or suture is then used to approximate the skin and the penis is wrapped with a compressive dressing.
Nine patients underwent the combined surgery. There were no intraoperative complications. In follow-up, 1 patient developed an infection-related complication that required device removal and immediate replacement. The remaining 8 did well postoperatively with improved dorsal phallic length with no infection or device-related complications.
Concurrent suprapubic lipectomy and placement of a 3-piece IPP is a safe and reproducible technique for the treatment of suprapubic lipodystrophy, buried penis, and refractory ED.

UNASSIGNED: Isolated male epispadias is a rare entity with incidence of approximately 1 in 120,000 live births. Epispadias usually presents with a phimotic preputial orifice where glans is not visible and hence is also known as concealed epispadias. Buried penis in children is defined as a congenital insufficient penile skin with an unretractable foreskin that keeps the penis deep inside the pre-pubic fat. This congenital malformation of the penile envelopes is usually isolated. However, in some cases the concealed penis hides an underlying penile anomaly. We present surgical repair of a very rare case with concealed epispadias.
METHODS: A nine-month-old infant had buried his penis, and his mother was seeking his circumcision. Local examination revealed concealed penopubic epispadias. A pediatric surgeon operated on this patient using the modified partial penile disassembly technique. The patient was doing well at follow-up visits at one, three, and six months. There were no urethral stricture or obstructive urinary symptoms. The parents were satisfied with the cosmetic outcome.
UNASSIGNED: The embryogenesis and development of the urethra and the prepuce are linked. Urethral development defects (as in hypospadias or epispadias) are frequently coupled with faulty prepuce on the same side. The goal of surgical management for epispadias is to correct the dorsal chordee and reconstruct the epispadiac urethra and glans. Based on the cosmesis of the penis reconstruction, preservation of erectile function, and achieving urine continence, the outcome is evaluated.
CONCLUSIONS: Concealed epispadias is frequently ignored because patients appear with buried penis, non-retractile prepuce, and a normal urine stream. Preoperative diagnosis and parent counseling are critical for the effective treatment of this uncommon entity. The modified partial penile disassembly procedure, in which the tunica albuginea is stitched to the pubic periosteum at 3 and 9 o\'clock, can be used to correct buried epispadias.
