Local therapy for penile cancer provides robust survival and can preserve the penis functionally and cosmetically. Interventions must target the appropriate clinical stage. We reviewed studies regarding the primary therapy in penile cancer, from topical therapy to radical penectomy, and reconstructive techniques. Topical therapy (5-FU or Imiquimod) provides a robust oncologic response in patients with Ta or Tis disease. Multiple laser therapies are available for localized patients and those with low-grade T1 disease. There is a non-trivial risk of progression and nodal metastases in poorly selected patients. Wide local excision provides an oncologically sound option in patient with up to T1 disease; less evidence exists for Mohs microsurgery in the setting of penile cancer. Increasingly aggressive approaches include glansectomy and partial/radical penectomy, which provide 5- and 10-year cancer-specific survival rates of over 80%. Meticulous reconstruction is necessary for the durable function of the remaining penis. Preservation of voiding and sexual function occurs via penile skin grafting, glans resurfacing, creation of a functional penile stump, and phalloplasty with a penile implant. Perineal urethrostomy provides an alternative in pathology demanding extensive partial or radical penectomy, and a durable option for seated voiding. Clinical suspicion and timely diagnosis are paramount in terms of management as less-invasive options for earlier-stage disease develop.

Tissue engineering for penile corpora cavernosa defects requires microvascular system reconstruction.GelMA hydrogels show promise for tissue regeneration. However, using stem cells faces challenges such as immune rejection, limited proliferation and differentiation, and biosafety concerns. Therefore, acellular tissue regeneration may avoid these issues. Exosomes are used from muscle-derived stem cells (MDSCs) to modify 3D-printed hydrogel scaffolds for acellular tissue regeneration. Hypoxia-preconditioned MDSC-derived exosomes are obtained to enhance the therapeutic effect. In contrast to normoxic exosomes (N-Exos), hypoxic exosomes (H-Exos) are found to markedly enhance the proliferation, migration, and capillary-like tube formation of human umbilical vein endothelial cells (HUVECs). High-throughput sequencing analysis of miRNAs isolated from both N-Exos and H-Exos revealed a significant upregulation of miR-21-5p in H-Exos following hypoxic preconditioning. Further validation demonstrated that the miR-21-5p/PDCD4 pathway promoted the proliferation of HUVECs. Epigallocatechin gallate (EGCG) is introduced to improve the mechanical properties and biocompatibility of GelMA hydrogels. EGCG-GelMA scaffolds loaded with different types of Exos are transplanted to repair rabbit penile corpora cavernosa defects, observed the blood flow and repair status of the defect site through color Doppler ultrasound and magnetic resonance imaging, and ultimately restored the rabbit penile erection function and successfully bred offspring. Thus, acellular hydrogel scaffolds offer an effective treatment for penile corpora cavernosa defects.

OBJECTIVE: Genital burns are rare injuries. Reconstruction of penile skin defects should consider cosmetic and functional outcomes. Skin grafts can develop scar contractures and carry hair follicles, causing unwanted results. These downsides remain unsolved issues. This work aimed to describe a new foreskin advancement flap method for completely reconstructing penile shaft skin defects in severely burned patients.
METHODS: From 2021 to 2023, four patients with third-degree burns in the genital area were enrolled in this investigation. We describe a series of cases with deep burns to the penile shaft and surrounding area that needed debridement and reconstruction using a novel technique called \"reverse circumcision,\" which consists of tangential excision of the penis and a foreskin advancement flap without longitudinal cuts with less morbidity, preservation of function, and a better aesthetic appearance. The patients had an average follow-up of nine months.
RESULTS: The reverse circumcision technique was established for patients with severe burns in the genital area. The four patients were satisfied with the postoperative results and the aesthetic results of the procedure without reporting any complications. No scarring or contractures were observed on the glans or penile shaft after surgery.
CONCLUSIONS: Compared with other flap methods, the use of a reverse circumcision foreskin advancement flap was more straightforward, feasible, and effective. In adults, the foreskin tissue completely covers the penile shaft skin defect. It is a viable reconstructive surgical technique that is easily reproducible and has excellent aesthetic and functional results. For this surgical technique, tissue transfers, bulky regional flaps, or skin grafts were not needed.

Penile strangulation secondary to utilization of a constrictive ring is a rare urologic emergency that requires urgent decompression to prevent prolonged vascular obstruction resulting in necrosis and gangrene. Current literature is mainly comprised of case presentations that focus on management in the acute setting via removal of the ring. Herein, we describe surgical management of a patient who presents in delayed fashion after self-removal of the constrictive ring. We discuss our penectomy-sparing technique of debridement and split thickness skin graft.

BACKGROUND: Penile amputation is an unusual situation reported globally as isolated cases and small series. It constitutes a urological emergency which requires microsurgical skills for the repair of the penis. We present a case of a penile amputation and discuss the management of this challenging condition.
METHODS: A 47-year-old patient presented to the emergency room with total amputation of corpora cavernosa of the penis resulting from knife aggression. The patient underwent successful microsurgical replantation, demonstrating positive progression and satisfactory results.
UNASSIGNED: Microneurovascular repair of penile amputation is the gold standard. Recommendations include a meticulous anastomosis, and a focus on vein anastomoses for optimal outcomes as well as associating a psychiatric approach. The PENIS score classifies the severity of lesion and predict postoperative complications and main outcomes.
CONCLUSIONS: Penile amputation presents a distinctive challenge, necessitating microsurgical anastomosis, meticulous tissue management, and adherence to established protocols are imperative for effectively managing such intricate cases. Even in cases of posttraumatic partial penile amputation after a long period, can yield satisfactory morphofunctional outcomes.

Objective We aimed to evaluate both the long-term surgical outcomes and patient-reported outcomes of free scapular flap (FSF) phalloplasty. Method The same surgical team performed phalloplasty in 66 patients using a FSF between March 2000 and September 2018. All patients had at least 24 months of follow-up. The surgical techniques used, complications observed, and surgical and patient-reported outcomes were retrospectively described. Results A total of 66 patients with indications of penile trauma (n = 19), micropenis (n = 42), and self-amputation (n = 5) underwent FSF phalloplasty. Two patients (3%) had total flap necrosis and 1 (1.5%) had partial flap necrosis. The urethral complication rate was 18.2% (12/66 patients). All patients were able to void while standing after revision procedures or urethroplasty. We found that an FSF is a reliable donor site for penile reconstruction. Conclusion The FSF phalloplasty creates an esthetically pleasing penis and allows voiding while standing. Most patients can engage in sexual activity. The main drawbacks of using this method are that patients experience different degrees of sensory recovery, and patients undergoing surgery with the \"tube-in-tube\" technique may find they are be limited by the thickness of the flap. However, by making full use of residual tissue, such as the micropenis glans or scrotal skin, patients can obtain good tactile and erogenous sensation. We believe that using an FSF complements the existing phalloplasty techniques.
RésuméObjectif Les chercheurs ont voulu évaluer les résultats chirurgicaux à long terme et les résultats cliniques déclarés par les patients d’une phalloplastie par lambeau scapulaire libre (LSL). Méthodologie La même équipe chirurgicale a effectué la phalloplastie de 66 patients au moyen d’un LSL entre mars 2000 et septembre 2018. Ceux-ci ont tous reçu un suivi d’au moins 24 mois. Les chercheurs ont décrit rétrospectivement les techniques chirurgicales utilisés, les complications observées et les résultats chirurgicaux et cliniques déclarés par les patients. Résultat Au total, 66 patients ayant des indications de traumatisme pénien (n=19), un micropénis (n=42) et une auto-amputation (n=5) ont subi une phalloplastie par LSL. Deux patients (3 %) ont subi une nécrose totale du lambeau et un (1,5 %) une nécrose partielle du lambeau. Le taux de complications urétrales s’est élevé à 18,2 % (12 patients sur 66). Tous les patients étaient en mesure d’uriner debout après les interventions de révision ou l’urétroplastie. Les chercheurs ont constaté que la région scapulaire est un siège de donneur fiable pour la reconstruction pénienne. Conclusion La phalloplastie par LSL crée un pénis à l’esthétique agréable, qui permet d’uriner debout. La plupart des patients peuvent se livrer à des activités sexuelles. Les principaux inconvénients de cette méthode proviennent du fait que les patients éprouvent divers degrés de récupération sensorielle et que ceux qui subissent la technique chirurgicale « à double tube » peuvent être limités par l’épaisseur du lambeau. Cependant, grâce au plein usage des tissus résiduels, tels que le gland du micropénis ou la peau du scrotum, les patients peuvent éprouver de bonnes sensations tactiles et érogènes. Les auteurs sont d’avis que l’utilisation du LSL complète les techniques de phalloplastie en place.

To report outcomes of surgical treatment in patients with penile foreign body granuloma and compare surgical outcomes between single- and two-stage scrotal flap reconstructions.
Medical records of patients with penile foreign body granuloma who underwent surgical treatment were reviewed. Patients with single- and two-stage scrotal flap reconstructions were compared.
Forty-two patients underwent surgical treatment from January 1, 2018 to October 31, 2022. Twenty-three patients underwent single-stage reconstruction with bilateral scrotal flap while 12 patients underwent two-stage repair with 19 operations. Five patients underwent circumcision; one had excision with primary closure. Another patient underwent reconstruction by penile skin preservation technique. There was no statistically significant differences between single- and two-stage groups in wound infection (8.69% vs. 0%, RR 2.71, 95%CI; 0.14-52.29), wound dehiscence (21.74% vs. 8.33%, RR 2.61, 95%CI 0.34-19.87), reoperation rate (26.08% vs. 8.33%, RR 3.13, 95%CI; 0.42-23.10). Postoperative fever was significantly higher in single-stage group (56.52 vs. 8.33%, RR 6.78, 95%CI; 1.01-43.83). Total length of hospital stay was shorter in single-stage group (7.43 ± 3.19 days vs. 10.86 ± 1.57 days, MD -3.42, 95%CI; -5.28 to -1.57). Incidence of patients without Clavien-Dindo surgical complications was significantly lower in single-stage group (43.48% vs. 83.33%, RR 0.53, 95%CI; 0.31-0.89).
Both single- and two-stage techniques may be considered for penile foreign body granuloma reconstruction. Although the hospital stay was longer in two-stage group, the complication rates were lower.

Organ-sparing surgery (OSS) in penile cancer management aspires to maintain organ form and function and preserve health-related quality of life (HRQoL), yet there is a lack of integrated evidence exploring these outcomes.
The aim sought to review HRQoL, functional, aesthetic, and psychological outcomes following OSS or radical penectomy for penile cancer.
A systematic review of MEDLINE and Cochrane databases included studies reporting on function (sexual, urinary or sensory), genital appearance or HRQoL/psychological well-being following surgical treatment of primary penile cancer. English-language reports (2000-2022), incorporating patient-reported or objective clinical outcome measures, were eligible. Studies of nonsurgical treatment strategies and those in the context of metastatic disease were excluded. Data were compiled and analyzed.
Twenty-six studies were included. Sexual function was the most studied outcome (754 pooled respondents; 19 studies), most frequently with the original 15-item and abridged 5-item International Index of Erectile Function. Preservation of erectile function following OSS is generally described, with some reduction in overall sexual satisfaction cited. Heterogeneous assessment of voiding function with little preoperative evaluation render interstudy comparison difficult. Most patients appear able to void from a standing position following OSS, with spraying the most common symptom. Maintenance of some sensory function is described with both split-thickness skin grafting and urethral glanduloplasty following radical glansectomy. Limited studies suggest reasonable patient satisfaction with genital cosmesis post-OSS. A negative impact on HRQoL is described in most studies following penile cancer surgery, variably correlated with aggressiveness of penile surgery and addition of lymphadenectomy. Anxiety, depression, and reduced self-esteem have been reported in penile cancer survivors. Relationship well-being varies, with some survivors reporting this to be unchanged.
OSS can preserve elements of sexual, urinary, and sensory function, supporting advantages over radical penectomy for eligible patients. However, a comprehensive understanding remains limited due to small, heterogeneous patient cohorts, challenges in obtaining premorbid data, and variability in outcome measures. Standardization of patient-reported outcomes following OSS is desirable.
