Robot-assisted VVF (RA-VVF) repair has the advantage of small cystotomy, precise dissection and minimal surrounding tissue trauma. Translation of this to better functional outcomes is not studied so far. This study aims to evaluate the quality of life, voiding, and sexual dysfunction following robot-assisted VVF repair. Women with successful RA-VVF repair were screened using UDI-6, IIQ-7, FSFI, and WHOQOL-BREF questionnaires. The preoperative assessment was done in the prospective cohort only. Of the 75 women who underwent RA-VVF repair, 47 were enrolled, 33 in retrospective, and 14 in a prospective cohort. Overall, 28 (60%) women had urinary complaints with a median UDI-6 total score of 4 (0–100) and IIQ-7 score (0–23) in 5 (10%) women. However, UDS (15 women) showed no DO with cystometric capacity (352 ± 98.12) ml and normal compliance in 14 (93%) women. Mean BOOI and DCI were 11.90 ± 7.01 and 44.25 ± 8.60 respectively, with PdetQmax ranging from 17 to 44. None had difficulty in voiding (Qmax 13.85 ± 4.90). Twenty (43%) women were sexually active, and 2 had sexual dysfunction (FSFI score < 26.55). Quality of life was “good” to “very good” in all domains (score > 90) except for the social domain. The prospective cohort showed significant improvement in UDI-6 score (p < 0.05), IIQ-7 score (p < 0.05), and quality of life (p < 0.05) postoperatively. RA-VVF repair results in minimal voiding dysfunction and significant improvement in overall quality of life. For sexual dysfunction assessment, a longer follow-up is required.

Background: Transurethral resection of bladder tumors (TURBT) surgeries requires post‐resection catheterization for continuous irrigation of the bladder. This indwelling catheter is associated with distressing catheter‐related bladder discomfort (CRBD) and increases postoperative pain and agitation.Objectives: To prove the hypothesis that transurethral 100 mg lidocaine irrigation at the end of TURBT can reduce the frequency of moderate‐to‐severe postoperative CRBD.Methods: 116 patients scheduled for TURBT were screened, 94 were recruited and completed the study. American Society of Anesthesiologists Physical Status I–II adult patients, 20–75 years of age undergoing elective TURBT surgery under general anesthesia were included. Transurethral normal saline with 0.01% lidocaine (100 mg in 1 L NS) was used for irrigation 30 min before the completion of surgery in group L, while only normal saline was used for transurethral irrigation in group N. The main outcomes were frequency of CRBD, pain and patient satisfaction at 0, 1, 2, and 6 h postoperatively.Results: A total of 94 patients were analyzed in the study. The incidence of moderate–severe CRBD was significantly lower in group L as compared to group C at 0, 1, and 2 h (65.9% vs. 31.9%, p = 0.01; 31.9% vs. 10.6%, p = 0.012; 21.3% vs. 2.1%, p = 0.004, respectively). At the 6‐h mark, the incidence of CRBD was lower in group L, although this did not achieve statistical significance (6.38% vs. 2.1%; p = 0.613).Conclusion: Irrigation with 0.01% lidocaine (100 mg) towards the end of TURBT reduces the incidence of moderate–severe CRBD by 52% and increases patient satisfaction.

BACKGROUND: There is an ongoing need and search for a simple yet accurate nephrometry scoring system for predicting the postoperative outcomes after partial nephrectomy (PN). Simplified PADUA Renal (SPARE) Nephrometry Scoring System, a simplified version of Preoperative Aspects and Dimensions Used for an Anatomical Classification (PADUA) has been proposed as a predictor of postoperative complications following PN recently. However, this score has never been externally validated and assessed as a predictor of trifecta and pentafecta outcomes of PN. In the current study, we applied the SPARE scoring system to our robot-assisted PN cohort (RAPN). METHODS: Prospectively maintained data of patients, who underwent RAPN from November 2014 to December 2018, was abstracted. Imaging was analyzed to calculate SPARE and RENAL nephrometry scores (RNS) by two urologists, independently. SPARE was compared with complications, trifecta outcomes, pentafecta outcomes, and RENAL nephrometry scoring (RNS). RESULTS: Data of 201 RAPN patients were analyzed. The mean SPARE score was 3 (range 0-11). One hundred thirteen patients were classified as low risk, 64 as intermediate risk, and 24 as high risks. On multivariate analysis SPARE score alone predicted complications (OR=1.37, P=0.014) and trifecta outcomes (OR=0.75, P=0.000) while age (OR=0.96, P=0.042), preoperative eGFR (OR=0.97, P=0.001) and SPARE scores (OR=0.81, P=0.016) were predictors for pentafecta outcomes. Receiver operated curve (ROC) analysis between SPARE and RNS in predicting the complications; trifecta and pentafecta outcomes had a comparable area under the curve. CONCLUSIONS: Our study validates the SPARE nephrometry scoring system in predicting postoperative complications, trifecta, and pentafecta outcomes in a RAPN cohort. The predictive accuracy of SPARE is similar to RNS.

Introduction Various in vitro and in vivo animal studies have shown that adenosine triphosphate (ATP) has a stimulatory role and nitric oxide (NO) has an inhibitory role in modulating bladder contractility. However, it is not known what happens to the urinary levels of ATP and NO in humans with underactive bladder (UAB). Methods In this prospective case–control study, we compared ATP and NO levels in twenty six male patients of UAB with a bladder contractility index (BCI) of < 100 and 18 healthy male volunteers without any lower urinary tract symptoms (LUTS). Results The mean urinary ATP levels were significantly lower in cases compared to controls (546.1 ± 37.3 pg/µl vs. 610.7 ± 24.9 pg/µl, p value < 0.001) and the mean NO levels were significantly higher in cases compared to controls (1233.4 ± 91.2 pg/µl vs. 1126.3 ± 91.3.4 pg/µl, p value < 0.001). The mean NO/ATP ratio in cases was significantly higher than that of controls (2.26 ± 0.2 vs. 1.84 ± 0.18, p value < 0.000). Using receiver operating curve (ROC) analysis, we noted the area under the curve (AUC) for NO/ATP ratio to be 0.91 in the diagnosis of cases. A cut-off value of 2.06 for NO/ATP ratio had sensitivity, specificity and diagnostic accuracy of 88.5%, 88.9% and 88.6%, respectively, in diagnosing patients with UAB. Conclusion Patients with UAB have significantly higher levels of urinary NO and decreased levels of urinary ATP. Urinary NO/ATP levels can be considered as a noninvasive alternate test for diagnosing bladder underactivity.

Background/Objective: Managing long-segment bilateral ureteral strictures in the mid/upper ureters with chronic renal insufficiency (CRI) and small bladder capacity is challenging. A Boari flap is not an option caused by low bladder capacity. Ileal replacement of the ureteral strictures risks worsening metabolic-acidosis in CRI.^1,2 In this situation, a buccal mucosal graft is a safe and effective surgical technique.^3,4 Buccal mucosal graft ureteroplasty is associated with high success rates and a low rate of complications.⁵ This video presents a robot-assisted buccal mucosa graft ureteroplasty to treat long-segment bilateral ureteral strictures in a patient with CRI and small bladder capacity. Materials: A 54-year-old lady with a history of genitourinary-tuberculosis was found to have bilateral long-segment ureteral strictures and upstream hydroureteronephrosis. The patient was initially managed with anti-tubercular treatment (ATT) and bilateral Double-J stents. She completed 6 months of ATT and the stents were replaced with bilateral percutaneous-nephrostomies because of persistent hydronephrosis. After drainage, the serum creatinine (SCr) was 2.2 mg/dL with a glomerular filtration rate of 24.7 mL/(min·1.73 m²) and a urinary bladder capacity of 200 mL. A simultaneous antegrade and retrograde contrast study showed a stricture length of 4–5 cm on each side located in the mid/upper ureter. Bilateral buccal mucosal grafts ureteroplasty were then offered as a solution to this problem using the Da Vinci Si system. Results: The operative time was 230 minutes with blood loss of 50 mL. Postoperative recovery was uneventful. At 6 months, SCr was 1.8 mg/dL with unobstructed drainage through both ureters on a renal dynamic scan. Conclusions: Buccal mucosa graft ureteroplasty is a well-suited procedure for reconstruction of long-segment ureteral strictures that are not amenable for routine procedures. No competing financial interests exist. Runtime of video: 6 mins 50 secs

Introduction: Miniaturization of percutaneous nephrolithotomy (mPCNL) was proposed to decrease postoperative bleeding, as there is decreased parenchymal injury compared with standard percutaneous nephrolithotomy (SPCNL). Published randomized controlled trials (RCTs) evaluating bleeding after mPCNL have shown conflicting results. Hence, the evidence to say that mPCNL offers less postoperative bleeding is not robust. Materials and Methods: Prospective RCT was done by comparing mPCNL and SPCNL for treatment of renal stones of size 1 to 3 cm. Patients with active urinary tract infection, renal malformation, uncorrected coagulopathy, and raised serum creatinine (>1.5 mg/dL) were excluded. Blood loss was evaluated by measuring fall in hemoglobin and hematocrit on postoperative day 1. Postoperative pain was evaluated by visual analogue scale (VAS) score at 6, 24, and 48 hours. Results: A total of 60 patients (30 in each arm) were enrolled during the study period. All the baseline preoperative variables were comparable in both the groups. The SPCNL group had a significantly higher drop in hematocrit level as compared with mPCNL (4.6 ± 3.1% vs 3.1 ± 2.1%, p = 0.02). The mean fall in hemoglobin was higher in SPCNL as compared with mPCNL (1.61 ± 0.9 gm% vs 1.21 ± 0.7 gm%, p = 0.07), but it was not significant. Blood transfusion (BT) rate was comparable in both the groups (one patient in each group). The mPCNL group had significantly less VAS scores at 6 hours (3.27 ± 1.20 vs 4.40 ± 1.52, p = 0.002) and 24 hours (2.10 ± 0.54 vs 2.83 ± 1.05, p = 0.001) after surgery. Postoperative complications and hospital stay were comparable in both the arms. Conclusion: mPCNL is associated with less postoperative bleeding and pain than SPCNL. However, the small tract size does not prevent against the clinically significant bleeding requiring BT.
