RESUMEN
Despite the widespread use of narrow diameter inflatable penile prosthesis (IPP) cylinders in patients with corporal fibrosis, outcomes data is sparse. We evaluated patients who underwent IPP placement with AMS™ 700 Controlled Expansion Restricted (CXR) cylinders from 2007-2021. Patient characteristics, device details, and surgical outcomes were assessed. A non-validated questionnaire was also distributed to patients to assess satisfaction. Among 982 IPPs placed over the study period at our institution, 49 (5.0%) used CXR cylinders. Indications for narrow cylinders: prior explant for infection (67.3%), ischemic priapism (16.3%), and idiopathic fibrosis (16.3%). Median corporal length was 19 cm (IQR 17-21 cm). Discordant intraoperative corporal measurements (24.5%) and RTE lengths (26.5%) were common. Post-operative complications occurred in 8 patients (16.3%) and included 3 infections (6.1%), 2 cylinder herniations (4.1%), 2 mechanical failures (4.1%), and one case of glans necrosis (2.0%). Five of these (10.2%) required explantation, while 4 (8.2%) were managed with revision. Over the follow-up period, 73.5% of patients reported satisfaction with rigidity. Primary drivers of dissatisfaction were perceived loss of penile length and girth. The AMS™ 700 CXR is a useful tool for challenging corporal fibrosis cases and shows acceptable surgical outcomes with moderate patient acceptability.
RESUMEN
BACKGROUND: Penile deformities due to Peyronie's Disease (PD) often significantly impair men's sexual health and quality of life. AIM: In this article we discuss the extratunical graft (ETG) procedure as a management strategy for PD patients with hourglass or indent penile deformities. METHODS: We compiled descriptions of surgical techniques and performed a review of the literature regarding ETG for PD. OUTCOMES: The ETG procedure appears to have promising results in the management of indent/hourglass deformity of PD. RESULTS: The findings of this review of the literature demonstrate that ETG is a safe and effective reconstructive technique for penile deformity with minimal side effects. CLINICAL IMPLICATIONS: We recommend utilizing ETG with or without plication for PD patients with indent or hourglass deformities. STRENGTHS AND LIMITATIONS: Strengths of ETG are the improvement in patients with tunical indents and hourglass deformities secondary to PD. Additionally, patients who underwent ETG maintained sexual function given no significant change in penile length and intact erectile function. Limitations, however, are that the procedure is relatively new, and data are limited to small cohorts. CONCLUSION: The ETG procedure is a safe and effective for management of complex PD in the short- and intermediate-term follow-up cohort.

OBJECTIVE: To assess surgical success and patient-reported outcomes of perineal urethrostomy via midline approach. MATERIALS AND METHODS: Charts of patients undergoing primary perineal urethrostomy between May 2008 and June 2022 were reviewed. Background characteristics were assessed; success was defined as freedom from re-intervention. Patient-reported outcome measures were assessed using a cross-sectional phone survey. Several validated questionnaires were used to assess lower urinary tract symptoms, quality of life, and erectile dysfunction. RESULTS: Among 1768 urethroplasties performed over the study period, 103 patients (5.8%) underwent midline perineal urethrostomy. Surgery was successful in 95.1% of cases (98/103); 5 patients (4.9%) required re-intervention at a median of 8.7 months. Post-operative complications occurred in 5.8% of cases (6/103) and were both mild and self-limited. Forty-nine patients (47.6%) were reached via phone survey at a median of 61 months post-operatively. Some questions were not answered by all patients. Most patients (42/49, 86%) were satisfied or very satisfied with surgical results, and 82% (40/49) reported an improvement in their overall health. Most patients (31/41, 76%) were unbothered by sitting to urinate. Although 20% of patients (10/49) reported post-operative urinary symptoms that interfered "a lot" with their daily life, only 3 (6%) of these patients reported dissatisfaction with the outcome. Regarding sexual function, 64% (27/42) reported indifference to or increased satisfaction with sexual encounters vs before surgery. The rate of de novo erectile dysfunction was 24% (12/49). CONCLUSION: The midline approach to perineal urethrostomy provides excellent, durable success rates with high levels of patient satisfaction.

Objective: The aim of this study is to report the updated 2-year results of the intervention arm of the ROBUST III randomized trial evaluating the safety and efficacy of the Optilume drug-coated balloon (DCB) versus standard endoscopic management of recurrent male anterior urethral stricture. Materials and Methods: Eligible patients included men with recurrent anterior urethral stricture ≤3 cm in length and ≤12Fr in diameter, International Prostate Symptom Score (IPSS) ≥11 and peak flow rate (Qmax) <15 mL/s. Patients were randomized to treatment with the Optilume DCB or standard-of-care endoscopic management. Primary efficacy endpoints measured at 2 years included freedom from re-intervention and changes in IPSS, Qmax and post-void residual (PVR). Secondary endpoint was impact on sexual function using the International Index of Erectile Function (IIEF). Primary safety endpoint was freedom from serious procedure- or device-related adverse events (AEs). Results: A total of 127 patients enrolled at 22 sites in the United States and Canada (48 randomized to standard-of-care dilation and 79 to DCB dilation). Seventy-five patients in the DCB arm entered the open-label phase after 6 months. Participants averaged 3.2 prior endoscopic interventions (range 2-10); most (89.9%) had bulbar strictures with an average stricture length of 1.63 cm (SD 0.76). Significant improvements in IPSS, average Qmax and PVR were maintained at 2 years. Freedom from repeat intervention was significantly higher in the Optilume DCB arm at 2 years versus the Control arm at 1 year (77.8% vs. 23.6%, p < 0.001). During the follow-up period, there were 15 treatment failures and two non-study-related deaths. Treatment-related AEs were rare and generally self-limited (haematuria, dysuria and urinary tract infection). Conclusion: The Optilume DCB shows sustained improvement in both objective and subjective voiding parameters at 2-year follow-up. Optilume appears to provide a safe and effective endoscopic treatment alternative for short recurrent anterior urethral strictures among men who wish to avoid or delay formal urethroplasty.
RESUMEN
Prolonged ischemic priapism presents a treatment challenge given the difficulty in achieving detumescence and effects on sexual function. To evaluate current practice patterns, an open, web-based multi-institutional survey querying surgeons' experience with and perceived efficacy of tunneling maneuvers (corporoglanular tunneling and penoscrotal decompression), as well as impressions of erectile recovery, was administered to members of societies specializing in male genital surgery. Following distribution, 141 responses were received. Tunneling procedures were the favored first-line surgical intervention in the prolonged setting (99/139, 71.2% tunneling vs. 14/139, 10.1% implant, p < .001). Although respondents were more likely to have performed corporoglanular tunneling than penoscrotal decompression (124/138, 89.9% vs. 86/137, 62.8%, p < .001), penoscrotal decompression was perceived as more effective among those who had performed both (47.3% Very or Extremely Effective for penoscrotal decompression vs. 18.7% for corporoglanular tunneling; p < .001). Many respondents who had performed both tunneling procedures felt that most regained meaningful sexual function after either corporoglanular tunneling or penoscrotal decompression (33/75, 44.0% vs. 33/74, 44.6%, p = .942). While further patient-centered investigation is warranted, this study suggests that penoscrotal decompression may outperform corporoglanular tunneling for prolonged priapism, and that recovery of sexual function may be higher than previously thought after tunneling procedures.

Purpose: Male stress urinary incontinence (SUI) has detrimental and long-lasting effects on patients. Management of this condition is an evolving field with multiple options for surgical treatment. We sought to review the pre-operative evaluation, intra-operative considerations, post-operative care, and future directions for treatment of male SUI. Methods: A literature review was performed using the PubMed platform to identify peer-reviewed, English-language articles published within the last 5 years pertaining to management of male stress urinary incontinence with an emphasis on devices currently on the market in the United States including the artificial urinary sphincter (AUS), male urethral slings, and the ProACTTM system. Patient selection criteria, success rates, and complications were compared between the studies. Results: Twenty articles were included in the final contemporary review. Pre-operative workup most commonly included demonstration of incontinence, PPD, and cystoscopy. Definition of success varied by study; the most common definition used was social continence (0-1 pads per day). Reported rates of success were higher for the AUS than for male urethral slings (73-93% vs 70-90%, respectively). Complications for these procedures include urinary retention, erosions, infections, and device malfunction. Newer treatment options including adjustable balloon systems and adjustable slings show promise but lack long-term follow-up. Conclusion: Patient selection remains the primary consideration for surgical decision-making for management of male SUI. The AUS continues to be the gold standard for moderate-to-severe male SUI but comes with inherent risk of need for revision. Male slings may be a superior option for appropriately selected men with mild incontinence but are inferior to the AUS for moderate and severe incontinence. Ongoing research will shed light on long-term results for newer options such as the ProACT and REMEEX systems.
RESUMEN
BACKGROUND: Despite technical advancements, inflatable penile prostheses (IPPs) are inherently at risk of mechanical failure given their nature as hydraulic devices. AIM: To characterize IPP component failure location at the time of device revision and stratify by manufacturer: American Medical Systems (Boston Scientific [BSCI]) and Coloplast (CP). METHODS: A retrospective review of penile prosthesis cases from July 2007 to May 2022 was conducted, identifying men who underwent revision surgery. Cases were excluded if documentation did not denote the cause of failure or the manufacturer. Mechanical indications for surgery were categorized by location (eg, tubing, cylinder, or reservoir leak; pump malfunction). Nonmechanical revisions were excluded (component herniation, erosion, or crossover). Categorical variables were assessed with Fisher exact or chi-square analysis; Student t-test and Mann-Whitney U test were used for continuous variables. OUTCOMES: Primary outcomes included specific location of IPP mechanical failure among BSCI and CP devices and time to mechanical failure. RESULTS: We identified 276 revision procedures, 68 of which met inclusion criteria (46 BSCI and 22 CP). Revised CP devices were longer than BSCI devices (median cylinder length, 20 vs 18 cm; P < .001). Log-rank analysis revealed a similar time to mechanical failure between brands (P = .096). CP devices failed most often due to tubing fracture (19/22, 83%). BSCI devices had no predominant site of failure. Between manufacturers, tubing failure was more common in CP devices (19/22 vs 15/46 for BSCI, P < .001), while cylinder failure was more common among BSCI devices (10/46 vs 0/22 for CP, P = .026). CLINICAL IMPLICATIONS: The distribution of mechanical failure is significantly different between BSCI and CP devices; this has implications regarding the approach to revision surgery. STRENGTHS AND LIMITATIONS: This is the first study to directly compare when and where mechanical failure occurs in IPPs and to compare the 2 main manufacturers head-to-head. This study would be strengthened by being repeated in a multi-institutional fashion to provide more robust and objective evaluation. CONCLUSION: CP devices commonly failed at the tubing and rarely elsewhere, while BSCI devices showed no predominant failure site; these findings may inform decision making regarding revision surgery.

To present our 12-year experience using an endoscopic approach to manage bladder neck contracture (BNC) without adjunctive intralesional agents and compare it to published series not incorporating them, we retrospectively reviewed 123 patients treated for BNC from 2008 to 2020. All underwent 24 Fr balloon dilation followed by transurethral incision of BNC (TUIBNC) with deep incisions at 3 and 9 o'clock using a Collins knife without the use of intralesional injections. Success was defined as a patent bladder neck and 16 Fr cystoscope passage into the bladder two months later. Most with recurrent BNC underwent repeat TUIBNC. Success rates, demographics, and BNC characteristics were analyzed. The etiology of BNC in our cohort was most commonly radical prostatectomy with or without radiation (36/123, 29.3%, 40/123, 32.5%). Some had BNC treatment prior to referral (30/123, 24.4%). At 12-month follow-up, bladder neck patency was observed in 101/123 (82.1%) after one TUIBNC. An additional 15 patients (116/123, 94.3%) had success after two TUIBNCs. On univariate and multivariate analyses, ≥2 endoscopic treatments was the only factor associated with failure. TUIBNC via balloon dilation and deep bilateral incisions without the use of adjunctive intralesional injections has a high patency rate. History of two or more prior endoscopic procedures is associated with failure.
RESUMEN
ABSTRACT Purpose To characterize the most common presentation and clinical risk factors for artificial urinary sphincter (AUS) cuff erosion to distinguish the relative frequency of symptoms that should trigger further evaluation in these patients. Materials and Methods We retrospectively reviewed our tertiary center database to identify men who presented with AUS cuff erosion between 2007 - 2020. A similar cohort of men who underwent AUS placement without erosion were randomly selected from the same database for symptom comparison. Risk factors for cuff erosion - pelvic radiation, androgen deprivation therapy (ADT), high-grade prostate cancer (Gleason score ≥ 8) - were recorded for each patient. Presenting signs and symptoms of cuff erosion were grouped into three categories: obstructive symptoms, worsening incontinence, and localized scrotal inflammation (SI). Results Of 893 men who underwent AUS placement during the study interval, 61 (6.8%) sustained cuff erosion. Most erosion patients (40/61, 66%) presented with scrotal inflammatory changes including tenderness, erythema, and swelling. Fewer men reported obstructive symptoms (26/61, 43%) and worsening incontinence (21/61, 34%). Men with SI or obstructive symptoms presented significantly earlier than those with worsening incontinence (SI 14 ± 18 vs. obstructive symptoms 15 ± 16 vs. incontinence 37 ± 48 months after AUS insertion, p<0.01). Relative to the non-erosion control group (n=61), men who suffered erosion had a higher prevalence of pelvic radiation (71 vs. 49%, p=0.02). Conclusion AUS cuff erosion most commonly presents as SI symptoms. Obstructive voiding symptoms and worsening incontinence are also common. Any of these symptoms should prompt further investigation of cuff erosion.
RESUMEN
Transurethral balloon dilation (BD) is a minimally invasive treatment for urethral stricture disease (USD) performed primarily or as a recurrence salvage maneuver. With the introduction of drug-coated balloons, we sought to characterize patient outcomes using non-medicated balloons. A retrospective review identified patients who underwent BD from 2007 to 2021. Patient and stricture characteristics were collected. All dilations employed the 24Fr UroMaxTM system. Clinical failure was defined by patient-reported lower urinary tract symptom recurrence or need for further stricture management. Ninety-one patients underwent BD with follow-up median (IQR) 12 (3-40) months. Most (75/91, 82%) had prior treatment for USD (endoscopic 50/91 (55%), 51/91 (56%) urethroplasty) before BD. Recurrence rates did not significantly differ between treatment-naïve and salvage patients (44% vs. 52% (p = 0.55)). Median (IQR) time to failure was 6 (3-13) months. The most common complications were urinary tract infection (8%) and post-operative urinary retention requiring catheterization (3%). Radiation history was noted in 33/91 (36%) with 45% recurrence. Patients without previous radiation had a similar recurrence rate of 52% (p = 0.88). Balloon dilation had minimal complications and overall, 50% recurrence rate, consistent regardless of stricture characteristics, radiation history, or prior treatments. These results represent an important clinical benchmark for comparing outcomes using drug-coated balloons.

OBJECTIVE: To evaluate the clinical and prognostic details of periurethral abscess (PUA) formation following urethroplasty (UP). METHODS: A retrospective review was performed to identify men who developed PUA after UP between 2007 and 2019 at a single tertiary care referral center. Patient demographics, stricture characteristics, and UP technique were recorded. Outcomes included time to PUA, presenting symptoms, wound cultures, imaging, and ultimate management. Comparative analysis between PUA and non-PUA patients was performed using Fisher's Exact test and Student's t-test. RESULTS: Among 1499 UP cases, 9 (0.6%) developed PUA. Mean stricture length was 4.6 cm with most located in the bulbar urethra (5/9, 56%), while 4/9 (44%) had undergone prior UP. PUA rates were 7/288 (2.4%) and 2/815 (0.3%) for substitution and anastomotic UP respectively. Voiding cystourethrogram (VCUG) demonstrated extravasation in 67% (4/6) of available UP cases imaged. Subsequent VCUG confirmed leak improvement or resolution in all cases. Wound cultures were frequently polymicrobial (4/6, 67%). Management included antibiotics with (6/9) and without (3/9) incision and drainage (I/D). Urinary drainage was performed in 5 patients using suprapubic tube (3/5) and foley placement (2/5). PUA resolution was observed in all patients while stricture symptom recurrence was observed in 2/9 (22%) patients with mean time to recurrence of 15 months. Overall mean follow-up time was 22 months. CONCLUSION: PUA is a rare complication of UP that may be more common in setting of postoperative urine leak. PUA is safely managed with I/D, urethral rest, and antibiotics, with low risk of recurrent stricture formation thereafter.

AIMS: To examine the rate of lower urinary tract complications (LUTC) and urinary diversion (UD) after artificial urinary sphincter (AUS) explantation with the acute reconstruction of AUS cuff erosion defects. METHODS: We performed a retrospective study of patients who underwent in-situ urethroplasty (ISU) for AUS cuff erosion from June 2007 to December 2020. Outcomes included LUTC (urethral stricture, diverticulum, fistula), AUS reimplantation, and UD. Defect size was prospectively estimated acutely and a subanalysis was performed to determine the impact of erosion severity (small erosions [<33% circumferential defect] and large erosions [≥33%]) on these outcomes. Kaplan-Meier curves were created to compare survival between the two groups. RESULTS: A total of 40 patients underwent ISU for urethral cuff erosion. The median patient age was 76 years old with a median erosion circumference of 46%. The overall LUTC rate was 30% (12/40) with 35% (14/40) of patients requiring permanent UD. Secondary AUS placement occurred in 24/40 (60%) patients with 11/24 (46%) leading to repeat erosion. On subanalysis, small erosion was associated with improved LUTC-free and UD-free survival but not associated with AUS reimplantation. CONCLUSIONS: Lower urinary tract complications are common after AUS cuff erosion and can lead to the need for permanent UD. Patients with larger erosions are more likely to undergo UD and reach this end-stage condition earlier compared to patients with small erosions.

OBJECTIVE: To evaluate the distance from critical pelvic structures (CPS, defined as bladder and iliac vessels) among inflatable penile prosthesis (IPP) reservoirs placed into the space of Retzius (SOR) and high submuscular (HSM) locations using cross-sectional imaging. IPP reservoir placement into the HSM location has been proposed as a strategy to prevent injury due to greater distance from CPS. METHODS: Our institutional database was retrospectively reviewed to identify men who underwent IPP insertion between 2007 and 2020 and had available cross-sectional abdominopelvic imaging after the time of surgery. Patients were grouped based on reservoir placement technique (SOR vs. HSM). Staff radiologists blinded to placement technique evaluated reservoir position to determine the shortest distance between CPS and the reservoir and if a mass effect was present on CPS. Variables were analyzed using chi-squared, Fisher's exact, and student's T-tests as indicated. RESULTS: Among 1,010 IPP cases performed during the study interval, 139 (13%) were imaged. Compared with SOR reservoirs (n = 32), HSM reservoirs (n =107) were significantly less likely to induce a mass effect on the bladder (72 vs. 9%, P = <.01) or iliac vessels (34 vs. 4%, P = <.01) and were located roughly 5 times further from the bladder (10 ± 22 vs. 49 ± 36 mm, P = <.01) and iliac vessels (5 ± 9 vs. 23 ± 26 mm, P = <.01). CONCLUSION: This study radiographically confirms that IPP reservoirs are located significantly further away from CPS following HSM placement compared to SOR placement.

ABSTRACT Purpose: We aimed to assess failure rates of salvage interventions and changes in split kidney function (SKF) following failed primary repair of ureteropelvic junction obstruction (UPJO). Materials and Methods: A retrospective review of adult patients at an academic medical center who underwent salvage intervention following primary treatment for UPJO was performed. Symptomatic failure was defined as significant flank pain. Radiographic failure was defined as no improvement in drainage or a decrease in SKF by ≥7%. Overall failure, the primary outcome, was defined as symptomatic failure, radiographic failure, or both. Results: Between 2008-2017, 34 patients (median age 38 years, 50% men) met study criteria. UPJO management was primary pyeloplasty/secondary endopyelotomy for 21/34 (62%), primary pyeloplasty/secondary pyeloplasty for 6/34 (18%), and primary endopyelotomy/secondary pyeloplasty for 7/34 (21%). Median follow-up was 3.3 years following secondary intervention. Patients undergoing primary pyeloplasty/secondary endopyelotomy had significantly higher overall failure than those undergoing primary pyeloplasty/secondary pyeloplasty (16/21 [76%] vs. 1/6 [17%], p=0.015). Among patients undergoing secondary endopyelotomy, presence of a stricture on retrograde pyelogram, stricture length, and SKF were not associated with symptomatic, radiographic, or overall failure. Serial renography was performed for 28/34 (82%) patients and 2/28 (7%) had a significant decline in SKF. Conclusions: Following failed primary pyeloplasty, secondary endopyelotomy had a greater overall failure rate than secondary pyeloplasty. No radiographic features assessed were associated with secondary endopyelotomy failure. Secondary intervention overall failure rates were higher than reported in the literature. Unique to this study, serial renography demonstrated that significant functional loss was overall infrequent.

INTRODUCTION: Previously, incisionless plication (IP) for correction of congenital penile curvature (CPC) has been performed after penile degloving via a circumscribing incision. AIM: To describe our experience with non-degloving incisionless penile plication (NDIP) for correction of CPC and compare these outcomes with those of men who underwent degloving incisionless penile plication (DIP). METHODS: We conducted a retrospective review of men ≤ 45 years of age who underwent incisionless penile plication for correction of CPC between 2008 and 2020 at two adult tertiary hospitals. Patients underwent either NDIP, performed through a 2-3 cm longitudinal incision along the proximal-to-mid shaft opposite the point of maximum penile curvature, or DIP via a sub-coronal circumscribing incision. MAIN OUTCOME MEASURES: Surgical and patient-reported outcomes were compared between the non-degloving and degloving groups. RESULTS: Among the 38 men (mean age, 26 years) who met the inclusion criteria, 25 underwent NDIP, including 6 patients with biplanar curvature (2 Ventral, 4 Dorsal, 6 Lateral). Thirteen patients underwent DIP, including 1 patient with biplanar curvature (1 ventral, 1 lateral). Curvature reduction was 50 ± 23 degrees for the NDIP group and 36 ± 10 degrees for the DIP group (P = .04). Five (20%) patients in the NDIP group and nine (69%) patients in the DIP group experienced a reduction in stretched penile length following plication (SPL) (P = .01). One patient in the NDIP group underwent an additional plication for recurrent curvature. CONCLUSION: Both NDIP and DIP are safe and highly efficacious techniques for the correction of CPC.

RESUMEN
BACKGROUND: Inflatable penile prosthesis (IPP) reservoirs are typically placed into the Space of Retzius (SOR) or alternative locations including the High Submuscular (HSM) space via transinguinal (TI) or counter incision (CI) techniques. A cadaver study showed variability in reservoir location after TI-HSM placement. AIM: To evaluate reservoir location using cross-sectional imaging following IPP insertion. METHODS: We retrospectively reviewed our institutional database and identified men who underwent virgin penoscrotal IPP insertion between 2007 and 2019. We then identified those men who subsequently underwent cross-sectional imaging prior to October 2019. Radiologists evaluated cross-sectional imaging in a blinded manner and categorized reservoir locations as follows: 1) submuscular; 2) posterior to the external oblique fascia and lateral to the rectus abdominis musculature; 3) preperitoneal; 4) retroperitoneal; 5) intraperitoneal; 6) inguinal canal; 7) subcutaneous. Patients were stratified by reservoir placement technique, transinguinal space of Retzius (TI-SOR), transinguinal high submuscular (TI-HSM), or counterincision high submuscular (CI-HSM). Clinical characteristics and outcomes were reviewed and compared. Statistical analysis was performed using Chi-squared and Fisher's exact tests. OUTCOMES: Variability exists in the TI placement of SOR and HSM reservoirs, CI-HSM reservoirs were associated with a low level of variability. RESULTS: Among 561 men who underwent virgin IPP insertion during the 12-year study period, 114 had postoperative cross-sectional imaging (29 TI-SOR, 80 TI-HSM, and 5 CI-HSM). Among the 114 patients imaged, TI-HSM reservoirs were more likely than TI-SOR to be located anterior to the transversalis fascia (48 vs 14%, P < .01) and were less likely to be located in the preperitoneal space (18 vs 62%, P < .01). Rates of intraperitoneal reservoir location were similar between the TI-HSM and TI-SOR groups (5 vs 7%, P = .66). Among imaged CI-HSM reservoirs, 4 (80%) were anterior to the transversalis fascia and 1 (20%) was within the inguinal canal. Among all 536 transinguinal cases (131 TI-SOR and 405 TI-HSM), rates of reservoir-related complications requiring operative intervention were similar between groups (5 vs 2%, P = .24). No complications were noted among the 25 patients in the CI-HSM cohort. CLINICAL IMPLICATIONS: The level of variability seen in this study did not seem to impact patient safety, complications were rare in all cohorts. STRENGTHS AND LIMITATIONS: This study is the first and largest of its kind in evaluating reservoir positioning in live patients with long-term follow-up. This study is limited in its retrospective and nonrandomized nature. CONCLUSIONS: Despite variability with both TI-HSM and TI-SOR techniques, reservoir related complications remain rare.

PURPOSE: We aimed to assess failure rates of salvage interventions and changes in split kidney function (SKF) following failed primary repair of ureteropelvic junction obstruction (UPJO). MATERIALS AND METHODS: A retrospective review of adult patients at an academic medical center who underwent salvage intervention following primary treatment for UPJO was performed. Symptomatic failure was defined as significant flank pain. Radiographic failure was defined as no improvement in drainage or a decrease in SKF by ≥7%. Overall failure, the primary outcome, was defined as symptomatic failure, radiographic failure, or both. RESULTS: Between 2008-2017, 34 patients (median age 38 years, 50% men) met study criteria. UPJO management was primary pyeloplasty/secondary endopyelotomy for 21/34 (62%), primary pyeloplasty/secondary pyeloplasty for 6/34 (18%), and primary endopyelotomy/secondary pyeloplasty for 7/34 (21%). Median follow-up was 3.3 years following secondary intervention. Patients undergoing primary pyeloplasty/secondary endopyelotomy had significantly higher overall failure than those undergoing primary pyeloplasty/secondary pyeloplasty (16/21 [76%] vs. 1/6 [17%], p=0.015). Among patients undergoing secondary endopyelotomy, presence of a stricture on retrograde pyelogram, stricture length, and SKF were not associated with symptomatic, radiographic, or overall failure. Serial renography was performed for 28/34 (82%) patients and 2/28 (7%) had a significant decline in SKF. CONCLUSIONS: Following failed primary pyeloplasty, secondary endopyelotomy had a greater overall failure rate than secondary pyeloplasty. No radiographic features assessed were associated with secondary endopyelotomy failure. Secondary intervention overall failure rates were higher than reported in the literature. Unique to this study, serial renography demonstrated that significant functional loss was overall infrequent.
