Lateral versus anterior approach for bladder neck dissection during robot-assisted radical prostatectomy: a pair-matched analysis to evaluate urinary continence and surgical margins.

INTRODUCTION: The preservation of the bladder neck during robot-assisted radical prostatectomy (RARP) could improve urinary continence recovery and limit the risk of positive surgical margins (PSMs). We refined our lateral approach to the bladder neck technique and compared its outcomes with those of the standard anterior approach. MATERIAL AND METHODS: From a retrospective analysis of 599 consecutive RARPs, 171 patients treated with the lateral and 171 patients treated with the anterior approach were pair-matched 1:1 on the basis of age, grade, and pathological stage. We described our surgical technique and compared the two approaches in terms of basal PSMs, recovery of urinary continence, and complications. RESULTS: As compared to the anterior approach, the lateral approach had shorter operative times and comparable rates of basal PSMs and postoperative complications. The rates of urinary continence after one, three, and 12 months were comparable between the two groups and were generally higher in localized disease. At regression analysis, predictors of urinary incontinence were only age, pathological stage T3b, ISUP grade 5 and nerve-sparing surgery. CONCLUSIONS: The lateral approach leads to an anatomical dissection of the bladder neck without increasing the risk of PSMs. However, no significant benefits in terms of continence recovery were demonstrated over the standard anterior approach.

Robot-assisted PSMA-radioguided Surgery to Assess Surgical Margins and Nodal Metastases in Prostate Cancer Patients: Report on Three Cases Using an Intraoperative PET-CT Specimen Imager.

INTRODUCTION: The aim of this feasibility study was to test the intraoperative use of this brand-new specimen PET/CT to guide robot-assisted radical prostatectomy and pelvic lymph node dissection. MATERIALS AND METHODS: Three cases of robot-assisted radical prostatectomy and pelvic lymph node dissection were performed with intraoperative use of the specimen imager. Surgeries were performed with Da Vinci Xi robot. An intravenous injection of 68Ga-PSMA-11 was performed in the OR and after complete excision, the specimens were analyzed with the imager. RESULTS: The average nodal yield was 17.3 (5.8 SD) nodes per patient. Specimen PET/CT images showed a focal uptake in a metastatic node (TBR 13.6), and no uptake or diffuse, faint uptake in negative nodes (TBR range: 1-5.3). The specimen imager provided intraoperative PET/CT images that clearly showed negative surgical margins in two patients, whereas the results were uncertain in a locally advanced case. CONCLUSION: The intraoperative use of the specimen PET/CT imager is safe and feasible and could improve the evaluation of prostate surgical margins and lymph node status.

Surgical and Functional Outcomes of Penile Amputation and Perineal Urethrostomy Configuration in Invasive Penile Cancer.

OBJECTIVE: The treatment of invasive penile cancer is based on partial or total penectomy and perineal urethrostomy configuration.1-3 To report surgical and functional outcomes of penile amputation and perineal urethrostomy configuration in a consecutive series of patients with invasive penile cancer. MATERIALS AND METHODS: A single-center retrospective analysis was conducted from January 2018 to December 2022. Data were extracted from clinical records and operative notes. As primary outcomes, surgical complications were described. Oncological outcomes through cancer-specific survival and overall survival were analyzed. Patient survival was estimated by a Kaplan-Meier analysis. Functional outcomes were assessed through the administration of the International Prostatic Symptoms Score (IPSS) questionnaire at 3 months follow-up. RESULTS: Overall 10 patients were enrolled. The median follow-up was 16 months (Interquartile range (IQR 12-18)). The median age was 71 years (IQR 63-79). Operative time was set at 195 minutes (IQR 155-275). The median hospital stay was 8 days (IQR: 6-10). Postoperative complications occurred in 20% of patients, in 1 case surgical revision was necessary. Positive surgical margins were detected only in 1 patient. The median catheterization time was 15 days (IQR: 15-32). One patient developed local recurrence. At 1 year, the cancer-specific survival was 80% and overall survival was 60%. The median preoperative IPSS was 15 (IQR 12-19). The median postoperative IPSS was 6 (IQR 5-7). CONCLUSION: Penile amputation and perineal urethrostomy configuration was demonstrated to be a safe and effective procedure to address invasive penile cancer.
