Open and Robotic Uretero-enteric Stricture Repair: Early Outcomes and Complications.

Objective: To characterize our single institutional experience with robotic and open uretero-enteric stricture (UES) repair. Materials and Methods: We queried our ureteral reconstructive database for UES repair between 01/2017 and 10/2023. Patients with <3 months follow-up were excluded. Prior to surgery, patients underwent ureteral rest (4 weeks) with conversion to nephrostomy tube. Clinical characteristics, complications, reconstructive success (uretero-enteric patency), need for repeat intervention, and renal function were assessed in patients undergoing open and robotic UES reconstruction. Results: Of 50 patients undergoing UES repair during the study period, 45 were included for analysis due to complete follow-up (34 [76%] robotic and 11 [24%] open repair). UES repair was performed in 50 renal units a median of 13 months (interquartile range 7-30) from index surgery, and most often involved the left renal unit (34/50; 68%). Compared with robotic, open cases were significantly more likely to have undergone open cystectomy (100% vs 68%, p = 0.04), have longer strictures (median 4 vs 1 cm, p < 0.001), require tissue substitution (27% vs 3%, p = 0.04), and have lengthier postoperative hospitalization (5 vs 2 days, p < 0.001). There was no significant difference in total operative time (410 vs 322 minutes) or 30d major complications (18% vs 21%). At a follow-up of 13 months, per patient reconstructive success was 100% (11/11) for open and 97% (33/34) for robotic, respectively. Conclusion: In select patients with short UES unlikely to require advanced reconstructive techniques, a robotic-assisted approach can be considered. Careful patient selection is associated with limited morbidity and high reconstructive success.

Evaluation of an Opioid-free Pathway for Perineal Reconstructive Surgery: A 1-year Pilot Study.

OBJECTIVE: To evaluate the impact of a standardized perioperative pain management pathway on postoperative opioid prescribing practices following male perineal reconstructive surgery at our institution. METHODS: Patients undergoing perineal reconstructive surgery (urethroplasty, artificial urinary sphincter, urethral sling) by a single surgeon from July 2022 to June 2023 were prospectively followed. A standardized nonopioid pathway was implemented in the perioperative period. Intraoperative local anesthetic included liposomal bupivacaine mixed with 0.25% bupivacaine. Opioids are administered in the recovery room at the discretion of anesthesiology providers. As of July 2022, our standard practice does not include a postoperative opioid prescription unless pain is poorly controlled in the recovery area. Postoperative communication encounters and opioid prescriptions were tracked through the electronic health record (EHR) in order to assess the efficacy of an opioid-free pathway. RESULTS: Sixty-seven patients met the criteria during the study period, 64/67 performed in an outpatient setting. 6/67 (9%) patients were prescribed an opioid postoperatively; 4 related to post-surgical pain, and 2 related to chronic pain. No refills were prescribed. Of the 26 patients who received an opioid in the recovery area, 2 (7.6%) were prescribed an opioid at discharge. 15/67 (22%) patients had a communication encounter related to pain within 30 days, most commonly related to bladder spasm management. Only 2 of these encounters resulted in an electronic opioid prescription. CONCLUSION: An opioid-free pathway is appropriate for opioid naive men undergoing perineal reconstructive surgery. When necessary, electronic opioid prescribing should be employed following discharge for breakthrough pain.

Postoperative Opioid Prescribing Following Outpatient Male Urethral Surgery: Evidence for Change.

INTRODUCTION: Surgeons play a central role in the opioid epidemic. We aim to evaluate the efficacy of a standardized perioperative pain management pathway and postoperative opioid requirements in men undergoing outpatient anterior urethroplasty at our institution. METHODS: Patients undergoing outpatient anterior urethroplasty by a single surgeon from August 2017 to January 2021 were prospectively followed. Standardized nonopioid pathways were implemented based on location (penile vs bulbar) and need for buccal mucosa graft. A practice change in October 2018 transitioned (1) from oxycodone to tramadol, a weak mu opioid receptor agonist, postoperatively and (2) from 0.25% bupivacaine to liposomal bupivacaine intraoperatively. Postoperative validated questionnaires included 72-hour pain level (Likert 0-10), pain management satisfaction (Likert 1-6), and opioid consumption. RESULTS: A total of 116 eligible men underwent outpatient anterior urethroplasty during the study period. One-third of patients did not use opioids postoperatively, and nearly 78% of patients used ≤5 tablets. The median number of unused tablets was 8 (IQR 5-10). The only predictor for use of >5 tablets was preoperative opioid use (75% vs 25%, P < .01). Overall, patients using tramadol postoperatively reported higher satisfaction (6 vs 5, P < .01) and greater percentages of pain reduction (80% vs 50%, P < .01) compared to those using oxycodone. CONCLUSIONS: For opioid-naïve men, 5 tablets or less of opioid medication with a nonopioid care pathway provides satisfactory pain control following outpatient urethral surgery without excessive overprescribing of narcotic medication. Overall, multimodal pain pathways and perioperative patient counseling should be optimized to further limit postoperative opioid prescribing.

Vesicourethral Anastomotic Stenosis Following Radical Prostatectomy: Risk Factors, Natural History, and Treatment Outcomes.

PURPOSE: Vesicourethral anastomotic stenosis after radical prostatectomy is a complication with significant adverse quality-of-life implications. Herein, we identify groups at risk for vesicourethral anastomotic stenosis and further characterize the natural history and treatment patterns. MATERIALS AND METHODS: Years 1987-2013 of a prospectively maintained radical prostatectomy registry were queried for patients with the diagnosis of vesicourethral anastomotic stenosis, defined as symptomatic and inability to pass a 17F cystoscope. Patients with follow-up less than 1 year, preoperative anterior urethral stricture, transurethral resection of prostate, prior pelvic radiotherapy, and metastatic disease were excluded. Logistic regression was performed to identify predictors of vesicourethral anastomotic stenosis. Functional outcomes were characterized. RESULTS: Out of 17,904 men, 851 (4.8%) developed vesicourethral anastomotic stenosis at a median of 3.4 months. Multivariable logistic regression identified associations with vesicourethral anastomotic stenosis including adjuvant radiation, BMI, prostate volume, urine leak, blood transfusion, and nonnerve-sparing techniques. Robotic approach (OR 0.39, P < .01) and complete nerve sparing (OR 0.63, P < .01) were associated with reduced vesicourethral anastomotic stenosis formation. Vesicourethral anastomotic stenosis was independently associated with 1 or more incontinence pads/d at 1 year (OR 1.76, P < .001). Of the patients treated for vesicourethral anastomotic stenosis, 82% underwent endoscopic dilation. The 1- and 5-year vesicourethral anastomotic stenosis retreatment rates were 34% and 42%, respectively. CONCLUSIONS: Patient-related factors, surgical technique, and perioperative morbidity influence the risk of vesicourethral anastomotic stenosis after radical prostatectomy. Ultimately, vesicourethral anastomotic stenosis is independently associated with increased risk of urinary incontinence. Endoscopic management is temporizing for most men, with a high rate of retreatment by 5 years.

Spinal anesthesia in infants undergoing urologic surgery duration greater than 60 minutes.

INTRODUCTION: Spinal anesthesia (SA) has been safely utilized in infants. There are limited data regarding the safety and efficacy of SA in pediatric urologic surgery lasting ≥60 min. We outlined the perioperative course for infants undergoing single-injection 0.5% plain bupivacaine SA-only for urologic procedures lasting ≥60 min. OBJECTIVE: To characterize the safety and efficacy of SA for urologic surgery in infants lasting ≥60 min. METHODS: We reviewed our prospectively maintained database of infants undergoing SA for urologic procedures lasting ≥60 min from May 2018 to March 2021. Patients received preoperative intranasal dexmedetomidine, some received intranasal fentanyl, and all patients received lidocaine cream applied preoperatively over the lumbar spine. Oral sucrose on a pacifier was provided as needed, and the patient's arms were swaddled for the procedure. Success was defined as no conversion to general anesthesia. Time points for start/end of spinal injection, procedure duration, wheels in/out of operating room (OR), and discharge were collected. RESULTS: Of 245 cases conducted with SA during the study period, 76 (31%) infants underwent surgery lasting ≥60 min. Of these, 73 (96%) were successfully completed with SA alone. In the 3 cases converted to general anesthesia, 2 (67%) required mask anesthesia after 96 and 169 min (for the last <10 min of surgery), and one was converted to intubation before start of surgery. Median patient age was 6 (IQR 5-7) months, and median procedure length was 95 (IQR 75-120) minutes. Following initial preoperative intranasal dexmedetomidine ± fentanyl, at least one additional dose of IV sedative was given in 27 (36%) cases at a median time of 90 (IQR 60-120) minutes into surgery. Following closure, patients exited the OR after a median 10 (IQR 8-12) minutes and subsequently discharged after spending a median of 73 (IQR 61-96) minutes in recovery. DISCUSSION: We describe pediatric urologic surgical cases lasting ≥60 min that employed single-injection intrathecal bupivacaine alone without adjunct intrathecal agents. In this report, SA was safely utilized in infants undergoing urologic procedures lasting at least 60 min, with about 40% of patients receiving additional IV dexmedetomidine and fentanyl. Non-medication measures (swaddling, oral sucrose) were important for maximizing patient comfort. Communication between surgeon and anesthesia as cases progress is key to maintaining adequate anesthesia. CONCLUSION: A single-injection bupivacaine-only spinal anesthesia approach for urologic surgery lasting over an hour and up to 3 h is safe and effective in infants. Selecting appropriate candidates for SA should be a joint decision between the surgeon and the anesthesiologist.

Surgical Correction of Adult Congenital Penile Curvature: A Systematic Review.

BACKGROUND: Congenital penile curvature (CPC) is corrected surgically by various corporoplasty or tunica albuginea plication techniques, but the optimal surgical approach is not well-defined. AIM: To provide a comprehensive evaluation of the published literature pertaining to outcomes with penile plication and corporoplasty techniques for surgical management of CPC. To determine if plication or corporoplasty offers superior outcomes in surgical correction of CPC. METHODS: A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Checklist. The following databases were queried from inception to March 18, 2020 to search for studies describing surgical treatment of CPC: Ovid MEDLINE(R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations and Daily, Ovid Embase, Ovid Cochrane Central Register of Controlled Trials, Ovid Cochrane Database of Systematic Reviews, and Scopus. OUTCOMES: Objective and subjective postoperative outcomes including penile straightening, shortening, penile sensory changes, and reoperation rates for both corporoplasty and tunica albuginea plication were summarized. RESULTS: Fifty-five articles comprising 2,956 patients with CPC who underwent a plication procedure (n = 1,375) or corporoplasty (n = 1,580) were included. The definition of "treatment success" varied widely and most often involved subjective patient reporting (22 studies; 40%) or objective assessment (15 studies; 27%). We considered curvature correction to be satisfactory if there was self-reported patient satisfaction or residual curvature after correction of <20˚. Reported rates of successful straightening ranged from 75 to 100% and 73 to 100% for plication and corporoplasty, respectively. A comprehensive and accurate assessment of surgical outcomes for CPC correction, such as satisfactory penile straightening, reoperation rates, glans sensory changes, and other complications was limited by significant inter-study heterogeneity with respect to the reporting of treatment outcomes. CLINICAL IMPLICATIONS: While both plication and corporoplasty appear to be safe and effective options in the treatment of CPC, definitive conclusions cannot be drawn with respect to treatment superiority due to low-quality study design, methodology flaws, and significant heterogeneity in reporting. STRENGTH & LIMITATIONS: This report represents the most comprehensive review of CPC surgical management. However, there is a significant lack of standardization in the reporting of treatment outcomes for CPC, thereby limiting the reliability of the published data summarization encompassed by our review. CONCLUSION: Both plication and corporoplasty demonstrate high success rates and relatively low complication rates in the treatment of CPC, albeit with low-level evidence available in most research publications. Robust comparison of the surgical techniques used to correct CPC is limited by significant variation in reporting methods used in the literature. C. J. Britton, F. A. Jefferson, B. L. Findlay, et al.

Robotic Urethral Reconstruction Outcomes in Men With Posterior Urethral Stenosis.

OBJECTIVE: To evaluate surgical outcomes stratified by posterior urethral obstruction (PUO) etiology in men undergoing definitive robotic posterior urethral reconstruction. MATERIALS AND METHODS: A retrospective, single surgeon, review of men undergoing robotic posterior urethral reconstruction between 2018 and 2020 was performed. Differences in complications, reconstructive success (no further intervention), and urinary continence by PUO etiology were assessed. RESULTS: Robotic posterior urethral reconstruction was performed in 21 men. PUO etiology included benign prostatic hypertrophy treatment in 5 (24%), prostatectomy in 10 (48%), radiation in 5 (24%), and trauma in 1 (5%). Median number of prior endoscopic treatments was 3 (benign prostatic hypertrophy), 3 (prostatectomy), and 2 (radiation) with an average time between obstruction and reconstruction of 9, 12, and 15 months (P = .52). Median length of stay after reconstruction was 2, 1, and 2 days (P = .45). Thirty-day complications occurred in 0%, 20%, 40% (P = .19). Post-reconstruction re-intervention was necessary in 0%, 10%, 80% (P = .004). Ultimately, anatomic success was achieved in 100%, 90%, 80% (P = .63), with functional success rates of 100%, 100%, 60% (P = .035). Median postoperative pad/day usage was 0,0, 10.5 (P <.001), and ultimately 0%, 30%, 80% (P = .013) underwent artificial urinary sphincter placement. CONCLUSION: Endoscopic treatment of posterior urethral obstruction (PUO) secondary to benign and malignant prostate conditions is associated with a high incidence of treatment failure. Robotic posterior urethral reconstruction is a safe and effective surgical solution for men with PUO in the absence of pelvic radiation. Men with pelvic radiation appear to be at increased risk of complications, PUO recurrence, and clinically significant stress urinary incontinence.

Incidence of Venous Thromboembolism and Safety of Perioperative Subcutaneous Heparin During Inflatable Penile Prosthesis Surgery.

OBJECTIVE: To identify the incidence of venous thromboembolism (VTE) risk factors, postoperative VTE, and to assess the morbidity of perioperative pharmacologic VTE prophylaxis in men undergoing inflatable penile prosthesis (IPP) surgery. METHODS: We retrospectively reviewed 215 patients undergoing IPP surgery between July 2017 and June 2019. Univariate and multivariate statistical analyzes were performed to assess pre-operative Caprini risk score and compare post-operative day 0 scrotal drain output, scrotal hematoma formation, and VTE in men who received subcutaneous heparin (SqH) vs those who did not receive SqH. RESULTS: Of 215 IPP patients, 84% were classified as high or highest risk for VTE utilizing the Caprini risk score. A total of 119 (55%) received perioperative SqH with or without additional anti-thrombotics. Post-operative day 0 scrotal drain output was higher in those who received SqH compared to those who did not receive SqH, 99.9 mL vs 75.6 mL, respectively (P = .001). Minor scrotal hematomas occurred in similar rates in patients who received perioperative SqH vs those who did not, 3.8% vs 6.3%, respectively (P = .38). Similar results were found on subgroup analysis when eliminating patients who received SqH concurrently with other anti-thrombotics. The overall rate of postoperative VTE was 0.9%. No post-operative infections occurred. CONCLUSION: Patients undergoing IPP surgery are at elevated risk for VTE. To our knowledge, this is the first study showing SqH use in the perioperative IPP surgery setting is safe when used in conjunction with a scrotal drain. Preoperative VTE risk stratification may be performed and can be used to guide clinical decision making regarding pharmacologic prophylaxis.

New perspectives on the surgical treatment of posterior urethral obstruction.

PURPOSE OF REVIEW: Posterior urethral obstruction (PUO) from prostate surgery for benign and malignant conditions poses a significant reconstructive challenge. Endoscopic management demonstrates only modest success and often definitive reconstructive solutions are necessary to limit morbidity and firmly establish posterior urethral continuity. This often demands a combined abdominoperineal approach, pubic bone resection, and even sacrifice of the external urinary sphincter and anterior urethral blood supply. Recently, a robotic-assisted approach has been described. Enhanced instrument dexterity, magnified visualization, and adjunctive measures to assess tissue quality may enable the reconstructive surgeon to engage posterior strictures deep within the confines of the narrow male pelvis and optimize functional outcomes. The purpose of this review is to review the literature regarding endoscopic, open, and robotic management outcomes for the treatment of PUO, and provide an updated treatment algorithm based upon location and complexity of the stricture. RECENT FINDINGS: Contingent upon etiology, small case series suggest that robotic bladder neck reconstruction has durable reconstructive outcomes with acceptable rates of incontinence in carefully selected patients. SUMMARY: Initial reports suggest that robotic bladder neck reconstruction for recalcitrant PUO may offer novel reconstructive solutions and durable function outcomes in select patients.

Long-term Success With Diminished Opioid Prescribing After Implementation of Standardized Postoperative Opioid Prescribing Guidelines: An Interrupted Time Series Analysis.

OBJECTIVE: To assess longitudinal prescribing patterns for patients undergoing urologic surgery in the nearly 2-year time frame before and after implementation of an evidence-based opioid prescribing guideline to accurately characterize the impact on postoperative departmental practices. PATIENTS AND METHODS: Historical prescribing data for adults who underwent 21 urologic procedures at 3 academic institutions were used to derive a 4-tiered guideline for postoperative opioid prescribing. The guideline was implemented on January 16, 2018, and prescribing patterns including quantity of opioids prescribed (in oral morphine equivalents [OMEs]) and refill rates were compared for opioid-naïve patients undergoing urologic surgery before (January 1, 2016, through January 15, 2018; N=10,649) and after (January 16, 2018, through September 30, 2019; N=9422) guideline implementation. Univariate analysis was performed using Wilcoxon rank sum and χ2 tests. Cochran-Armitage trend tests and interrupted time series analysis were used to test for significance in the change in OMEs prescribed before vs after guideline implementation. RESULTS: The median quantity of opioids decreased from 150 OMEs (interquartile range, 0-225) before guideline implementation to 0 OMEs (interquartile range, 0-90) after guideline implementation (P<.001). Median OMEs decreased significantly in each tier and each of 21 individual procedures. Overall guideline adherence was 90.7% (n=8547). Despite this decrease in OMEs prescribed, post-guideline implementation patients obtained fewer refills than the pre-guideline implementation group (614 [6.5%] vs 999 [9.4%]; P<.001). CONCLUSION: In a multi-institutional follow-up prospective study of adult urologic surgery-specific evidence-based guidelines for postoperative prescribing, we demonstrate sustained reduction in OMEs prescribed secondary to guideline implementation and adherence by our providers.

Long-acting liposomal bupivacaine and postoperative opioid use after Peyronie's disease surgery: a pilot study.

BACKGROUND: Novel strategies have been proposed to minimize postoperative opioid use, yet many patients experience significant pain after penile surgery. Our objective was to evaluate postoperative opioid use in patients undergoing penile ring block with long-acting liposomal bupivacaine (LB; Exparel) during surgery for Peyronie's disease (PD). METHODS: We identified patients who underwent tunica albuginea plication (TAP) and plaque excision/grafting (PEG) for PD between July 2019 and September 2020. Intraoperatively, a ring block was administered at the penile base penis with 20 cc of LB. Patients were instructed to use over the counter pain medications as first line treatment for postoperative pain, and opioids were available for severe breakthrough pain as needed [7.5 oral morphine equivalents (OME) =5 mg oxycodone]. Opioid use was assessed during the first five days postoperatively. RESULTS: In total, 28 patients met inclusion criteria including 18/28 (64%) who underwent TAP and 10/28 (36%) who underwent PEG. Median patient age was 56 years (IGR 51;61). Median postoperative 10-point visual analogue pain score was 0 (range 0-3). Duration of penile anesthesia ranged from 1.5-4 days. In total, 9/28 patients (32%) utilized opioids during the first five days postoperatively (range 7.5-75 OME). Two patients (7%) required opioids during the first two days after surgery. 27/28 (96%) were satisfied or highly satisfied with postoperative pain control. CONCLUSIONS: Intraoperative penile ring block with LB resulted in excellent pain control with local anesthetic duration of 1.5-4 days. The majority of patients did not require any opioids during the early postoperative period. Further study comparing outcomes with shorter-acting local anesthetics is necessary to balance pain control benefits with additional cost.

Use of Hyperthermic Intraperitoneal Chemotherapy (HIPEC) in Pediatric Sarcoma for Maximal Oncologic Control.

Few centers worldwide have trialed cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in pediatric rhabdomyosarcoma. This case involves a 5-year-old boy with gross hematuria who was found to have an 8 cm pelvic mass, likely arising from the prostate and extending along the bladder wall. Excisional biopsy revealed undifferentiated fusion negative sarcoma. The mass demonstrated reduction in size with chemotherapy and photon radiation therapy. He presented to our institution for delayed primary excision, and underwent cytoreductive surgery with hyperthermic intraperitoneal chemotherapy using cisplatin. Follow-up imaging 15 months postoperatively demonstrates no evidence of disease.

Primary Renal Ewing Sarcoma: A Case Report and Review of the Literature.

Primary Ewing sarcoma of the kidney is an extremely rare and aggressive tumor affecting young adults. We present the case of a 22-year-old male with primary Ewing sarcoma/primitive neuroectodermal tumor (EWS/PNET) of the kidney who underwent right radical nephrectomy and adjuvant chemo-radiation.
