Intraoperative ultrasonography (IOUS)-guided vs conventional laparoscopic nephrectomy: a randomised control trial.

OBJECTIVES: To assess the efficacy of routine use of intraoperative ultrasonography (IOUS) in improving perioperative outcomes in patients undergoing IOUS-guided laparoscopic nephrectomy (IOUS-LN) and conventional laparoscopic nephrectomy (C-LN). PATIENTS AND METHODS: This was a parallel-arm, single-blinded, randomised controlled trial (CTRI/2021/12/038906). All patients undergoing LN, either for benign or malignant causes, were included. Patients undergoing partial/cytoreductive nephrectomy, with venous thrombus were excluded. In the study arm, IOUS-guided renal vascular assessment was performed after colon mobilisation and a standard LN was performed in the control arm. The primary outcome was intraoperative duration. The secondary outcomes were blood loss, need for open conversion, blood transfusion, perioperative complications, duration of Intensive Care Unit (ICU) stay and length of hospitalisation (LOH). The patients were followed for 3 months after surgery. RESULTS: A total of 104 patients were included, with 52 in each arm. Demographic characteristics were comparable in both arms. A significant reduction in the operative duration (mean [sd] 181.69 [40.8] vs 199.7 [41.8] min, P = 0.02) was seen in the IOUS-LN group. The difference in blood loss showed no significant difference when compared between both groups (median [interquartile range] 84.55 [74-105.5] vs 99.95 [78.5-111] mL, P = 0.08). On subgroup analysis, the reduction in the operative duration was significant in patients who underwent laparoscopic simple nephrectomy (LSN; mean [sd] 194.4 [42.5] vs 221.2 [36.4] min, P = 0.01), whereas comparable operative durations were seen in patients undergoing laparoscopic radical nephrectomy (LRN; mean [sd] 168.96 [35.3] vs 178.3 [35.9] min, P = 0.34). Similar conversion rates were seen in both groups (P = 0.98) along with blood transfusions (P = 0.78). The LOH, ICU stay, and complications were similar in both groups. Significantly less blood loss (P = 0.03) was noted with IOUS in patients undergoing LSN. IOUS did not influence any outcomes in patients undergoing LRN. CONCLUSION: Intraoperative ultrasonography significantly reduced the operative duration in LN, but with no significant reduction in the volume of blood loss. Significant reduction in intraoperative duration and blood loss was seen in patients who underwent LSN on subgroup analysis.

Do Indian men have similar oncological outcomes with abiraterone plus androgen deprivation therapy in the setting of metastatic hormone-sensitive prostate cancer? A prospective observational study.

Introduction: Combination of abiraterone with androgen deprivation therapy (ADT) has better survival outcomes than ADT alone in metastatic Hormone-sensitive prostate cancer (mHSPC) in the Western population. In this prospective (Clinical Trials Registry-India [CTRI] registered) observational study, we present the comparative oncological outcomes of ADT alone and ADT + abiraterone in Indian patients, which is not available currently. Methods: This study (CTRI-number-CTRI/2020/07/026545) included newly diagnosed mHSPC patients from January 2020 to June 2023 in a tertiary care hospital, urology department. Patients fulfilling inclusion criteria were advised ADT with abiraterone (A + ADT), and those not affording received ADT monotherapy (ADT). The primary endpoint was overall survival (OS). Secondary outcomes included prostate-specific antigen (PSA) decline >90%, radiographic progression-free survival (rPFS), and PSA progression-free survival (pPFS). Results: Out of 278 patients with mHSPC, 163 patients were excluded and 115 were analyzed (ADT = 40 vs. A + ADT = 75). After a median follow-up of 20.3 months, 11 of 40 (27.5%) in ADT-only arm and 15 of 75 (20%) in ADT + abiraterone arm had died (Hazard-ratio of death 0.72; 95% confidence interval 0.68-0.88; P < 0.001). A PSA decline of >90% was seen in 85% in the ADT alone group and 93.3% in the ADT + abiraterone group. Significantly better outcomes of the ADT + abiraterone were seen in the secondary endpoints of rPFS (P < 0.001) and pPFS (P < 0.001). The OS benefit was 28% reduction in risk of death in our study versus 37% and 38% in STAMPEDE and LATITUDE, respectively. pPFS and rPFS were also poorer in Indian subsets. Conclusions: Abiraterone with ADT improves OS, PSA response, rPFS, and pPFS in the Indian population akin to the Western data but with poorer OS, rPFS, and PSA progression-free survival on comparison.

Pelvic lymph node dissection before or after laparoscopic radical cystectomy: An ambispective study comparing ease of surgery and operative outcomes.

Introduction: It is unclear when pelvic lymph node dissection (PLND) should be performed during laparoscopic radical cystectomy. Proponents of PLND performed before cystectomy claim that early PLND skeletonizes the urinary bladder's vascular pedicles, making cystectomy easy. Others contend that an early cystectomy provides space and flexibility during subsequent PLND. This first-of-its-kind study compared PLND before and after cystectomy for the ease of performing surgery (total operative time, cystectomy time, and PLND time) and the operative outcomes (number of lymph nodes removed, blood loss, and complication rates). Methods: This ambispective cohort study included a predetermined sample size of 44 patients. The first 22 patients underwent PLND after cystectomy (Group 1), and the following 22 underwent PLND before cystectomy (Group 2). The primary outcome was total operative time. Secondary outcomes included cystectomy time, PLND time, number of lymph nodes removed, blood loss, and complication rates. Results: The baseline characteristics were similar in both groups. The total operative time (344.23 ± 41.58 min vs. 326.95 ± 43.63 min, P = 0.19), cystectomy time (119.36 ± 34.44 min vs. 120.91 ± 35.16 min, P = 0.53), PLND time (126.82 ± 18.75 min vs. 119.36 ± 23.34 min, 0.25), number of dissected lymph nodes (13.27 ± 4.86 vs. 14.5 ± 4.76, P = 0.40), and blood loss (620.45 ± 96.23 ml vs. 642.27 ± 131.8 ml, P = 0.20) were similar in the two groups. The complication rates categorized by Clavien-Dindo grading were identical in the two groups. Conclusions: PLND done after cystectomy was comparable to PLND done before cystectomy regarding the ease of surgery and the operative outcomes.

Socio-economic, education, and insurance-related factors associated with the treatment completion rates in patients with nonmetastatic urinary bladder cancer: A Retrospective cohort study.

Introduction: Among urological malignancies, the diagnosis and treatment of urinary bladder cancer (UBC) incurs the highest cost per patient. Our objective was to broaden the current understanding of how demographic, socioeconomic, education, and insurance-related factors influence UBC management. Methods: Between January 2017 and December 2019, all patients with nonmetastatic bladder cancer were included. The demographic, treatment, and follow-up details were retrieved from a prospectively maintained database, and the Modified Kuppuswamy Index was used to evaluate the patients' socioeconomic level. Patients were divided into the completed treatment group, or the incomplete treatment group based on adherence to the initially intended treatment plan. Patients who presented with benign disease or metastases were not included. Results: Eighty-nine patients did not complete the initially intended course of treatment out of 132 patients who needed additional management after the initial transurethral resection. Comparable risk factors and demographic profiles existed in both groups. Patients with intermediate-risk disease are more likely to fail to adhere to the initial intended treatment (odds ratio [OR] = 0.09; 95% confidence interval [CI]: 0.02-0.30). On logistic regression analysis, upper socioeconomic status (OR = 6.8; 95% CI: 0.35-132.1) patients and patients with higher educational status of graduation or above (OR = 3.62; 95% CI: 0.75-17.43) had higher chances of treatment completion. Education status significantly impacted treatment completion on multivariate analysis (P = 0.01). Patients who utilized employer-funded insurance had better treatment compliance (OR = 4.1; 95% CI: 0.90-18.7). The compliance was unaffected by smoking, occupation, or other demographic factors. Conclusion: Patients with low economic status, low levels of education, and who need adjuvant intravesical therapy had considerably greater treatment dropout rates.

A Novel Technique for Hand-Assisted Laparoscopy in Difficult Nephrectomies-Is One Hand Better Than Two? A Single-Centre, Single-Surgeon Series.

Laparoscopic radical nephrectomy is the standard of care for T1 renal tumors and nowadays being used for T2 or higher tumors, resulting in higher the conversion rates. To bridge this gap, the hand-assisted laparoscopy (HAL) method was introduced. Even now, in the robotic era, this HAL approach continues to find importance in urology, especially in the most challenging cases, albeit, with a relatively low usage rate due to the cost involved and availability of hand port devices. Here, we report a case series using a novel modification of the HAL nephrectomy (HALN) technique when open conversion is needed. From a prospective database, we retrospectively analyzed the data of Six patients who underwent HALN at the All India Institute of Medical Sciences between January 2019 and December 2022. Indications for surgery included both malignant and benign renal disease. Four surgeries were performed on the right side while two were performed on the left. Five patients underwent a HALN for renal cell carcinoma (RCC) and 1 for a benign non-functioning kidney. In our series, all the cases with RCC had were T2a or higher. Our case series shows that HALN is technically safe, effective, and a great adjunct to conventional laparoscopy. The ingenious use of a surgical glove as a hand port is an easy-to-make-and- use device in such challenging surgeries.

Comparison Of Ventral Inlay and Dorsal Onlay Urethroplasty For Female Urethral Stricture.

OBJECTIVE: To compare the outcomes of Ventral inlay buccal mucosal graft urethroplasty (VIBMGU) with dorsal onlay buccal mucosal graft urethroplasty (DOBMGU) for the treatment of Female urethral stricture (FUS). MATERIAL AND METHODS: This study included women who underwent either VIBMGU or DOBMGU between January 2016 and June 2023. The preoperative American Urological Association (AUA) symptom scores, maximal urinary flow rate (Qmax), post-void residual volume (PVR) on ultrasonography, and length and location of the stricture were obtained from a prospectively maintained electronic database. The data obtained from the patient's last visit were compared with the preoperative values for this study. The primary outcome was the success rate. The secondary outcomes were changes in AUA score, PVR, and Qmax. The patient's last follow-up visit was considered for the duration of the follow-up. RESULTS: Seventy-three patients were treated for BMGU for FUS. Forty-six patients underwent VIBMGU, and 27 patients underwent DOBMGU. The median duration of follow-up was 27.5 (11.00-55.00) versus 14 (7.00-17.00) months, respectively. The success rates of VIBMGU and DOBMGU were 89.13% and 88.89%, respectively. There was a reduction in AUA scores and PVR and an improvement in Qmax postoperatively in both groups. The difference in the reduction in AUA scores between the VIBMGU and DOBMGU groups was statistically significant. The difference was not statistically significant in terms of reduction in PVR and improvement in Qmax between the 2 groups. CONCLUSION: The ventral inlay technique can provide equal results to the dorsal technique with the added advantage of vaginal sparing. This is the single largest series in the literature on FUS with the largest follow-up period of 90 months.

Efficacy of Low Dose Intravenous Epinephrine Infusion in Improving Perioperative Outcomes in Patients Undergoing Transurethral Resection of Prostate: A Prospective Parallel Arm Double-Blind Randomized Control Trial.

OBJECTIVE: To determine the efficacy of intraoperative low-dose intravenous epinephrine infusion in improving intraoperative bleeding and perioperative outcomes of transurethral resection of prostate (TURP) surgery. METHODS: This was a double-blinded, randomized control trial in which all patients undergoing bipolar TURP were included. Patients with uncontrolled hypertension, cardiac disease, and on anticoagulants were excluded. The study group received intravenous epinephrine, whereas the control group received normal saline at the same rate (0.05 µg/kg/min) throughout the procedure. Intraoperative blood loss was the primary outcome. The secondary outcomes were incidence of intraoperative hypotension (due to spinal anesthesia), resection time, indwelling catheter time, and length of hospitalization. RESULTS: Thirty-six patients were included in each group. Demographic and clinical profiles were comparable with an overall median prostate size of 41 (34-52) gram in both groups. The primary objective, mean intraoperative blood loss in the study group was lower than the control group but statistically insignificant (67.91+/-18.7 mL vs 75.14 +/-17.1 mL; P = .086). Incidence of intraoperative hypotension was significantly lower in the study group (8.3% vs 33.3%; P = .01). Rest of the secondary outcomes, resection time (83 (64-111.5) minutes vs 86 (68-94.75) minutes; P = .97), mean indwelling catheter time (P = .94), postoperative complications (P = .73), and length of hospitalization (P = .87) were comparable. CONCLUSION: In this first-of-its-kind trial, low-dose epinephrine infusion did not reduce intraoperative blood loss in patients undergoing TURP. However, it significantly reduced intraoperative hypotension, which complicates spinal anesthesia particularly in elderly population.
