PURPOSE/OBJECTIVE:Ileal ureter interposition is a well-established option for complex ureteral strictures. While minimally invasive approaches have evolved, the application of the single-port (SP) robotic platform for ileal ureter reconstruction has not been previously reported. This study presents the first clinical series evaluating the feasibility, technique, and early outcomes of SP robotic ileal ureter reconstruction. METHODS:We retrospectively reviewed a prospectively maintained database of patients who underwent SP robotic ileal ureter substitution between September 2019 and November 2024 by a single surgeon. Demographic, perioperative, and functional data were analyzed. Surgical success was defined as freedom from reintervention, absence of radiographic obstruction, and stable renal function. Pre- and postoperative renal function was compared using paired statistical analysis. RESULTS:Seventeen patients underwent SP robotic ileal ureter reconstruction (29% male), with a mean age of 54 years. Radiation-induced strictures accounted for 70.6% of cases. Unilateral reconstruction was performed in 8 (47.1%), while 8 (47.1) required bilateral reconstruction with V-shaped or reverse-7 configurations, including bladder augmentation in selected cases. One patient (5.9%) underwent unilateral ileal ureter with bladder neck reconstruction. The median ileal segment length was 25 cm. Mean operative time was 308 min, and median blood loss was 70 mL. One intraoperative complication (5.9%) occurred. Postoperative complications were observed in 47%, with 11.8% classified as Clavien-Dindo grade IIIa. Renal function remained stable (preoperative eGFR 56.4 vs. postoperative 57.5 mL/min/1.73 m², p = 0.803). At a median follow-up of 20.5 months, the overall success rate was 94.1%. CONCLUSIONS:Single-port robotic ileal ureter reconstruction is a feasible and effective technique for complex ureteral strictures, achieving high early success with acceptable morbidity.

BACKGROUND:Achieving adequate analgesia in patients undergoing vaginoplasty facilitates early ambulation, reduces postoperative morbidity and increases patient satisfaction. This study evaluated the use of intraoperative nerve blocks (transverse abdominis plane [TAP] block and perineal block) in reducing postoperative pain and decreasing opioid use in robotic-assisted peritoneal flap vaginoplasty. METHODS:A prospective cohort study of 150 consecutive adult patients undergoing robotic peritoneal flap vaginoplasty performed by the senior authors was conducted at a single institution from December 2023 to October 2024. 75 consecutive patients who did not receive a block and 75 consecutive patients who did receive blocks were included based upon power analysis calculations with assumptions yielding 99% power. Demographic data as well as multimodal analgesic use was compared between groups with respect to use during the preoperative, intraoperative, and post anesthesia phases of care, as well as on each day of inpatient admission. RESULTS:Groups did not differ significantly in baseline characteristics. Block-treated patients demonstrated a significantly reduced total opioid requirement throughout their hospital stay, inclusive of intraoperative and perioperative dosing, as measured in total morphine milligram equivalents (MME) (median 675 versus 26 MME; p < 0.001). Block-treated patients required almost no oxycodone or hydromorphone after surgery with a median oxycodone dose of 0 mg compared with 33 mg in controls (p < 0.001); their total median hydromorphone dose was 0.4 mg versus 1.2 mg (p < 0.001). CONCLUSIONS:The block intervention achieved a dramatic reduction in total postoperative opioid use (oral and intravenous) throughout the hospital stay.

The advent of the purpose-built da Vinci single-port robotic platform marks a pivotal advancement in minimally invasive urological surgery. Designed to overcome the ergonomic and technical limitations of prior single-site approaches, the single-port system enables complex procedures through a single incision, with enhanced dexterity, optimized use of confined spaces and improved cosmetic and peri-operative outcomes. The single-port system has been increasingly used across a wide range of urological indications, including robot-assisted radical prostatectomy, partial nephrectomy, nephroureterectomy and reconstructive surgeries such as pyeloplasty and ureteral re-implantation. Innovative access strategies, such as the single-port transvesical and low anterior access approaches, have facilitated regionalized and multi-quadrant surgeries without the need for repositioning or robot re-docking. These advances have translated into reduced morbidity, faster recovery and increased feasibility of opioid-sparing, same-day discharge protocols. As surgical expertise deepens and technology evolves, the single-port robotic platform stands as a refinement of minimally invasive surgery, and also as a potential paradigm shift in urological practice.

OBJECTIVE:To describes our institutional experience of a case series using a novel multi-segment, chimeric free ileal flap for posterior urethral reconstruction, focusing on surgical technique, perioperative management, and functional outcomes. Complex posterior urethral defects, particularly those resulting from radiation pose a significant reconstructive challenge that is not easily approachable with standard reconstructive techniques. In this case series, we present a novel approach for this complex problem. METHODS:We retrospectively reviewed consecutive patients who underwent posterior urethral reconstruction with a chimeric free ileal flap at our institution. Data were collected via chart review. RESULTS:Six male patients (median age: 61 years range: 59-77) with radiation-associated posterior urethral stenosis and bladder neck pathology underwent reconstruction. One was an active smoker; three had prior failed reconstructions. A 20-cm ileal segment was harvested and designed into a chimeric construct in all cases. The left deep inferior epigastric vessels were used for flap anastomosis. Median operative time was 717 minutes, and median hospital stay was 9 days. Two patients experienced early postoperative complications; none had flap loss. At median follow-up of 204 days, four patients had successful functional outcomes. One had persistent leak, and one required cystectomy for newly diagnosed squamous cell carcinoma found at the bladder neck on final pathology. CONCLUSIONS:Chimeric free ileal flap reconstruction is a novel management option for radiation-associated posterior urethral defects, offering well-vascularized, versatile tissue in patients unsuitable for traditional approaches. However, this approach is complex that requires multidisciplinary collaboration and extensive surgical planning.

BACKGROUND AND OBJECTIVE/OBJECTIVE:To report our multi-institutional outcomes with robotic intracorporeal ileal ureter replacement (RIUR). METHODS:We performed a retrospective review of patients who underwent RIUR at three institutions from April 2016 to June 2025. Surgical success was defined as the absence of flank pain and of ureteral obstruction on functional imaging and/or endoscopic evaluation, and freedom from operative intervention related to RIUR at ≥6-mo follow-up. KEY FINDINGS AND LIMITATIONS/UNASSIGNED:Of 48 patients, 31 (64.6%) had unilateral and 17 (35.4%) had bilateral reconstruction. Twenty (41.7%) had a history of radiation. Median stricture length was 20 cm (interquartile range [IQR] 20-25). In 19 patients (39.6%), a concomitant abdominopelvic reconstruction was performed (9 bladder augmentations, 5 contralateral ureteral reconstructions, and 5 other procedures). Median operative time was 359 min (IQR 292-418), estimated blood loss was 100 ml (IQR 50-175), and length of stay was 5 d (IQR 4-7). There were nine (18.8%) major (Clavien grade ≥III) 30-d complications: five urinary anastomotic leaks, two intra-abdominal abscesses, one small bowel leak that required exploratory laparotomy, and one renal bleed requiring angioembolization. Thirty-six patients (75%) had ≥6-mo follow-up, which confirmed surgical success in 33/36 (91.7%) at median follow-up of 24 mo (IQR 14-35). All three failures were in the radiation subgroup, which had a significantly lower rate of surgical success (76.9% vs 100%; p = 0.031). CONCLUSIONS AND CLINICAL IMPLICATIONS/CONCLUSIONS:RIUR is an effective and durable treatment for patients with devastating ureteral injuries. However, the procedure is challenging and associated with a significant major complication rate. PATIENT SUMMARY/RESULTS:This study looked at a complex surgery in which a piece of intestine is used to rebuild the urinary tube that drains urine from the kidney to the bladder. Across three hospitals, the procedure worked well for the large majority of patients, and helped to restore function and relieve symptoms.

PURPOSE:Robot-assisted surgical management of ureteral stricture is a relatively uncommon procedure with numerous techniques described. This literature review combined with expert opinion outlines the key surgical principles of ureteral reconstruction and proposes an algorithm for the robot-assisted treatment of ureteral strictures. METHODS:A narrative literature review was conducted using PubMed and Cochrane databases with a predefined search strategy including terms related to ureteroplasty and upper urinary tract reconstruction. The search yielded approximately 900 results. After screening, 219 relevant studies were selected for analysis. Two authors independently reviewed all included articles, and whenever evidence was inconsistent or insufficient, consensus was reached through discussion within the full author group. RESULTS:Robotic ureteral reconstruction includes several techniques, with the choice of procedure guided by multiple factors. Key principles include the use of healthy tissue, creation of a tension-free anastomosis, and ensuring adequate drainage. Outcomes may be further optimized by preoperative ureteral rest, intraoperative ureteroscopy, and the use of intravenous indocyanine green (ICG). Buccal mucosa grafting has emerged as a breakthrough in minimally invasive reconstruction. The robotic approach is adept at managing standard techniques such as ureteroureterostomy, psoas hitch, Boari flap, ureteroneocystostomy, and more recently described methods such as non-transecting ureteral reimplantation and bladder flap ureteroplasty. Ileal ureter remains a good option in cases of challenging reconstructions and patients with prior radiation therapy or extensive defects. CONCLUSION:Robot- assisted ureteral reconstruction has shifted the paradigm in stricture management, allowing complex reconstructive operations to be performed with minimally invasive techniques. This expert review summarizes key surgical approaches and presents a practical algorithm to guide urologists in the management of ureteral strictures.

OBJECTIVES/OBJECTIVE:To determine the early experience with paclitaxel-drug coated balloon (DCB) for both anterior urethral stricture disease (aUSD) and posterior urethral stenoses (PUS). METHODS:A retrospective review of patients undergoing Optilume® DCB in the Trauma and Urologic Reconstructive Network of Surgeons (TURNS) database was performed. Both functional (improved subjective voiding without a secondary procedure) and anatomic (open lumen on cystoscopy) success rates were determined. Kaplan Meier estimates were used to determine the risk of failure by LSE classification and LSE Stage. RESULTS:A total of 319 patients were treated with the DCB, of which 260 were for aUSD and 59 were for PUS. Median age was 64 years (Interquartile range [IQR] 48-73). Recurrence was noted in 119 patients (37.3%) at a median follow-up of 5.7 months (IQR 3-12). For aUSD, the 1-year functional recurrence-free survival was 78.4% (95% CI 71.8-85.4) and anatomical recurrence-free survival was 66.4% (95% CI 59.5-74.2). For PUS, the 1-year functional recurrence-free survival was 75.8% (95% CI 61.4-93.7) and anatomical recurrence-free survival was 59.4% (95% CI 44.1-80). Recurrences of any kind were significantly more likely in patients with strictures after hypospadias repair (HR 5.21, 95% CI 1.06-25.6, p=0.042), and use of 24 Fr, 3 cm DCB (HR 3.64, 95% 1.10-12.09, p=0.035). These were also significant predictors of anatomical recurrences. CONCLUSIONS:Multi-institutional utilization of the DCB for aUSD and PUS demonstrates a low effectiveness among high-risk strictures. Recurrence after DCB varies based on stricture characteristics and subtype, which are important for preoperative counseling and postoperative surveillance.
