To compare same-sitting bilateral vs unilateral retrograde intrarenal surgery (RIRS) in elderly patients, focusing on postoperative complications and stone-free rates (SFR).
Data from 2 multicenter databases, FLEXible ureteroscopy Outcomes Registry (FLEXOR) (unilateral RIRS) and same sitting bilateral-retrograde intrarenal surgery (SSB-RIRS) (bilateral RIRS), were analyzed, considering only patients aged 70+ with preoperative computed tomography. Patients were categorized into Group 1 (bilateral RIRS) and Group 2 (unilateral RIRS). Follow-up included imaging assessments and secondary treatments as needed.
Group 1 included 146 patients, while group 2 had 495. Group 1\'s patients were slightly older and had a higher prevalence of recurrent stone formation. Group 2 often underwent RIRS for incidental stones. Group 1 had larger and more pelvic stones. Laser lithotripsy and total operation times were significantly longer in Group 1. Group 2 had significantly higher overall stone-free rates, although there were no significant differences in ancillary procedures for residual fragments. Group 1 experienced more pelvicalyceal injuries needing stenting, postoperative fever, and post-op hematuria not requiring transfusion.
In conclusion, bilateral RIRS can be carefully considered in elderly patients. Preoperative counseling is essential for both primary and repeat RIRS procedures, and further research is needed to optimize instrument and laser strategies for better outcomes in elderly RIRS patients.

BACKGROUND: Percutaneous balloon compression (PBC) of the Gasserian ganglion is steadily gaining traction within the trigeminal neuralgia (TN) community. Bilateral trigeminal neuralgia (BTN) is a rare condition, and its treatment remains challenging. As far as we know, there are currently no research reports on the treatment outcomes of PBC for BTN.The purpose of this study is to meticulously evaluate the efficacy and safety of PBC for BTN in our medical institution.
METHODS: In this retrospective study, we collected and analyzed the medical records of all patients with BTN who underwent the PBC procedure at the Department of Neurosurgery at Hebei General Hospital from July 2017 to July 2023. After undergoing PBC therapy, all patients were promptly assessed for treatment efficacy based on the modified Barrow Neurological Institute (BNI) pain intensity grading scale.
RESULTS: All 37 patients with BTN experienced significant pain relief (BNI I-IIIb) immediately following unilateral PBC treatment. Among these patients, 25 reported relief from pain on the non-operative side, which was effectively managed with medication. Out of the 12 patients who did not experience improvement in contralateral symptoms, 11 received contralateral PBC. Out of the 48 treated sides, 47 sides (97.9%) achieved excellent pain control following a single PBC procedure. The follow-up times ranged from 2 to 62 months. At the 1-year follow-up, 94.6% of the patients maintained excellent therapeutic outcomes.Three recurrent patients underwent repeated unilateral PBC, and all of them maintained excellent pain control postoperatively. At the last follow-up, satisfaction was at 91.7% (measured using the Likert scale), with no severe complications occurring.
CONCLUSIONS: The results indicate that PBC is an effective and relatively safe method for treating BTN, offering a valuable option for pain control in these rare cases of TN.

Persistent hyperplastic primary vitreous (PHPV) is a rare congenital developmental ocular disorder caused by incomplete regression of the embryonic hyaloid vasculature; bilateral presentations are even rarer. We report a 6-year-old child with bilateral PHPV who visited our hospital for strabismus, without exhibiting leukocoria, microphthalmia, and systemic diseases. These unique characteristics distinguish our case from other cases of PHPV. It is crucial to increase awareness of congenital eye disease in children and the importance of performing fundus examination with the pupils dilated.

Dermoid cysts are one of the most common benign orbital tumours in children and usually occur unilaterally. Bilateral dermoid cysts in the orbit are rare. We report here, a case of bilateral orbital dermoid cysts, in a 29-month-old baby girl. The patient\'s prognosis was favourable following surgical resection. Through this case report, we hope to increase the recognition and understanding of this condition.

Genetic mutational characterization of synchronous bilateral male breast cancer (BC) has been poorly reported due to its rarity. Herein, we present a 55-year-old male patient who was diagnosed with bilateral breast cancer (BBC) and harbored different gene mutations. The diagnosis of synchronous bilateral breast cancer (SBBC) was made using ultrasonography, magnetic resonance imaging (MRI), mammography and core-needle biopsy. Subsequently, bilateral modified radical mastectomies were performed, and histopathologic examination revealed invasive ductal carcinoma. To further investigate the genetic profile of the patient, the biopsy tissue from both breasts and a blood sample were subjected to targeted next generation sequencing (NGS). The genomic profile of the left breast (LB) sample revealed two copy number variations (CNVs), amplification of MCL1 and DAXX, while the right breast (RB) sample showed no obvious mutation. We are reporting this case along with its clinicopathologic findings and genetic investigations, since SBBS occurs extremely rarely, especially in men. The heterogeneity in gene mutations observed in this case may suggest a different pathogenesis and the need for different therapy strategies.

UNASSIGNED: This study aimed to evaluate the efficacy and safety of same-session flexible ureteroscopy (fURS) for the treatment of bilateral upper urinary tract stones and to examine the influence of stone load on the outcome of same-session fURS, stratifying by total diameter of stones (TDS) ≤30 mm vs. >30 mm.
UNASSIGNED: We retrospectively reviewed all cases of same-session fURS performed for bilateral upper urinary tract stones at four institutions between January 2017 and September 2020. All patients were divided into two groups based on TDS, ≤30 mm and >30 mm. Data on patient demographics, stone characteristics, surgical results, and complications were collected and analyzed for differences between the two groups. Stone-free rate (SFR) was defined as patients endoscopically stone-free or with radiological fragments <2 mm of each renal unit.
UNASSIGNED: A total of 121 patients with bilateral upper urinary tract stones underwent same-session fURS, consisting of 73 patients in the TDS ≤ 30 mm group and 48 patients in the TDS > 30 mm group. The mean bilateral stone size was 28.2 ± 12.2 mm (range: 9.1-38.4 mm), with a mean operating time of 97.1 ± 39.6 min (range: 19-220 min). The SFR was 54.5% after the first fURS, and SFR increased to 97.5% after re-fURS for residual stones. The operation time for the TDS > 30 mm group was longer than that of the TDS ≤ 30 mm group (85.1 ± 36.5 vs. 115.4 ± 37.4 min, p < 0.001). The SFR after the first fURS was significantly lower in the TDS > 30 mm group than in the TDS ≤ 30 mm group (25.0% vs. 73.9%, p < 0.001). Although there was no statistically significant difference in overall SFR between the two groups (93.7% vs. 100%, p = 0.060), the rate of re-fURS for residual stones was higher in the TDS > 30 mm group than in the TDS ≤ 30 mm group (75% vs. 26%, p < 0.001). There were no significant differences in length of hospital stay (LOS) (2.2 ± 0.7 vs. 2.3 ± 1.0, p = 0.329) or complication rate (10.9% vs. 14.6%, p = 0.582) between the two groups.
UNASSIGNED: The results suggested that same-session fURS can be effectively performed with a low complication rate. A higher SFR after the first fURS can be achieved in the case of bilateral upper urinary tract stones with TDS ≤ 30 mm, and priority should be given to same-session fURS.

Our video demonstrates a modified gasless transaxillary endoscopic thyroid surgery with the posterior approach for bilateral low-risk thyroid cancer. In this paper, we provided a detailed introduction to the right gasless transaxillary endoscopic total thyroidectomy surgical procedure for bilateral low-risk thyroid cancer, and briefly summarized the Lei\'s seven-sinking method: sinking the clavicular head of the sternocleidomastoid muscle (CHSCM); sinking the cervical vascular sheath; sinking the right wall of the esophagus; sinking the right recurrent laryngeal nerve (RLN); sinking the trachea; sinking the left RLN and sinking the thyroid. A 5-cm incision was made starting from the anterior axillary line along the natural fold at the axilla. A trocar was placed in the axillary incision approximately 3-5 cm away from the side of the breast and slightly below the anterior axillary line. Using blunt dissection and electrocautery, a working space was created by elevating a subcutaneous flap above the pectoralis major muscle. The thyroid bed was accessed through the two heads of the SCM, and then the thyroid was separated from the strap muscles. Thyroidectomy and central lymph node dissection were fully endoscopically performed with the posterior approach using conventional endoscopic instruments. Through the posterior approach and the operation steps of the seven-sinking method, total thyroidectomy and bilateral central lymph node dissection can be achieved relatively easily.

Spontaneous renal rupture is a rare clinical condition characterized by spontaneous bleeding in the renal subcapsular and perinephric spaces in patients without a history of trauma. It occurs mainly in pathologic kidneys and after some renal surgeries. We report a 40-year-old male patient admitted with a diagnosis of gallstones with cholecystitis due to fever and abdominal pain after unilateral ureteral calculi. The patient developed delayed right renal rupture hemorrhage during treatment, controlled after selective arterial embolization (SAE). Still, the patient developed spontaneous left renal rupture due to a systemic inflammatory response. Finally, the patient\'s life was saved after several selective embolizations of the renal artery. We retrospectively analyzed this case to improve our understanding of the disease.

UNASSIGNED: To evaluate the clinical characteristics of simultaneous bilateral sudden sensorineural hearing loss (Si-BSSNHL) as well as its prognostic factors.
UNASSIGNED: Patients with Si-BSSNHL who were admitted to the Department of Otology Medicine between December 2018 and December 2021 were enrolled in the case group. Propensity score matching (PSM) for sex and age was used to select the control group, which included people who had unilateral sudden sensorineural hearing loss (USSNHL) during the same time period. Hearing recovery, audiological examinations, vestibular function assessments, laboratory tests, and demographic and clinical manifestations were analyzed for intergroup comparisons. Binary logistic regressions were used for both univariate and multivariate analyses of Si-BSSNHL prognostic factors.
UNASSIGNED: Before PSM, the Si-BSSNHL and USSNHL groups differed significantly (p < 0.05) in terms of time from onset to treatment, initial pure-tone average (PTA), final PTA, hearing gain, audiogram curve type, proportion of tinnitus, high-density lipoprotein level, homocysteine level, and effective rate. After PSM, significant differences were also observed in time from onset to treatment, initial PTA, final PTA, hearing gain, total and indirect bilirubin levels, homocysteine level, and effective rate between the two groups (p < 0.05). There was a significant difference in the classification of therapeutic effects between the two groups (p < 0.001). For prognostic analysis, the audiogram curve type was significantly different between the effective group and the ineffective groups of Si-BSSNHL (p = 0.01), in which the sloping type was an independent risk factor for the prognosis of the right ear in Si-SSNHL (95% confidence interval, 0.006-0.549, p = 0.013).
UNASSIGNED: Patients with Si-BSSNHL had mild deafness, elevated total and indirect bilirubin and homocysteine levels, and poorer prognosis than those with USSNHL. Audiogram curve type was linked to the therapeutic effect of Si-BSSNHL, and the sloping type was an independent risk factor for a poor prognosis in the right ear of Si-SSNHL.
