Survival outcomes of postchemotherapy retroperitoneal lymph node dissection for nonseminomatous germ cell tumors: A retrospective cohort study from a single tertiary center in South India.

Introduction: Chemotherapy, postchemotherapy retroperitoneal lymph node dissection (pcRPLND), and metastasectomy remain the standard of care for the management of advanced nonseminomatous germ cell tumor (NSGCT). Methods: We retrospectively studied 73 patients who had pcRPLND at a single tertiary-care center (2003-2022). Surgical and clinicopathological features and oncological outcomes are presented. Results: The mean age was 28.27 years (15-48). Three-fourths had Stage III disease at diagnosis. International Germ Cell Cancer Collaborative Group risk stratification was 54.54% and 21.21% in intermediate risk, and poor risk, respectively. Sixty-two patients had Standard, 7 had Salvage and 4 underwent Desperation pcRPLND. Eleven patients (15.06%) required adjunctive procedures. Thirteen patients (17.8%) had ≥ class 3 Clavien-Dindo complications and postoperative mortality occurred in 5 (6.8%) patients. The histopathologies (HPE) of the pcRPLNDs were necrosis, teratoma, and viable tumor in 39.7%, 45.2%, and 15.1%, respectively. Seven patients underwent metastasectomy. An 85% size reduction in the size of RPLN predicted necrosis. There was 71.4% concordance between pcRPLND and metastasectomy HPEs. The median follow-up was 26.72 months (inter-quartile range - 13.25-47.84). The 2-year recurrence-free survival (RFS) rate was 93% (95% confidence interval [CI]-83%-97%) and the overall survival (OS) rate was 90% (95% CI-80%-95%). This is the largest series of pcRPLND for NSGCT in India to our knowledge. Conclusion: Although most of the cohort belonged to stage III, an RFS and OS rate of >90% at 2 years was achieved. We believe that successful management of postchemotherapy residual masses in NSGCT is contingent on the availability of multidisciplinary expertise and is therefore best done at tertiary-care referral centers.

Satisfaction and genital perception after orchiectomy for prostate cancer: does the technique matter? A randomized trial.

OBJECTIVES: Bilateral extracapsular or total orchiectomy (BEO) for prostate cancer is presumed to have psychological consequences after the surgery due to perception of an empty scrotum. Bilateral subcapsular orchiectomy (BSO) was designed to preserve perception of palpable testes. We compared the patients' satisfaction and genital perception following BEO and BSO. MATERIALS AND METHODS: Prostate cancer patients eligible for androgen deprivation therapy who opted for orchiectomy were enrolled in prospective randomized study. Patients with bleeding disorder or uncorrected coagulopathy, poor performance score, and psychiatric problems were excluded. Outlook to life and own health in-general, overall satisfaction to the procedure and genital perception was evaluated using modified Fugl-Meyer questionnaire (FMQ) which was administered before and after 3 months of the surgery. Patients were randomized to BEO and BSO groups at the time of surgery using block randomization. Primary outcome was to compare the genital perception of testicular loss and patients' satisfaction to BSO and BEO. Secondary outcomes included testosterone and PSA control, operative time, and complications. RESULTS: Total 35 patients were enrolled in each group which was comparable. There was no difference in PSA control at 3 months. Mean operative time and blood loss were significantly lesser in BEO group. FMQ score at 3 months did not show significant difference. Majority of the patients in both groups were satisfied with procedure and the aesthetic value of scrotum after surgery. However, 84% in BSO group did not feel that testes were removed on self-examination, as compared to 28% in BEO group. Majority patients in both groups did not report physical or psychological discomfort from change in scrotal content. CONCLUSIONS: Results showed that patients' satisfaction and genital perception following BSO and BEO were similar. Feeling of remaining intrascrotal contents after BSO did not had added psychological advantage in terms of perception of genitalia.

Outpatient buccal mucosal graft urethroplasty outcomes are comparable to inpatient procedures.

BACKGROUND: We sought to compare outcomes between inpatient and outpatient buccal mucosal graft (BMG) urethroplasty among a large tertiary referral center series. METHODS: A retrospective review of consecutive patients who underwent BMG urethroplasty between 2007 and 2018 was performed, including only first stage and one stage graft procedures. Patients were divided into inpatient and outpatient groups. Demographic and outcome data were collected and analyzed, with success defined as no need for further endoscopic or open reoperative management. RESULTS: Of 143 patients undergoing BMG urethroplasty during the study period, 87 cases (60.8%) were performed on an inpatient basis, and 56 (39.2%) on an outpatient basis. Patient characteristics such as age, BMI, prior endoscopic procedures and co-morbid factors were similar between inpatient and outpatient groups. Perioperative characteristics such as estimated blood loss were also similar between groups, but the inpatient cohort had a longer operative time (157.6 vs. 123.1 min, P<0.0001). Operative success was comparable in the two groups (74.7% inpatient vs. 76.8% outpatient, P=0.7) as were rates of complications (29.9% inpatient vs. 26.8% outpatient, P=0.07). CONCLUSIONS: BMG urethroplasty can be safely performed in an ambulatory setting without increased complications or compromised outcomes.

Attitude and perceived barriers towards the practice of evidence-based urology amongst urological trainees in India.

INTRODUCTION: Evidence-based medicine requires systematic access and appraisal of contemporary research findings, followed by their application in clinical practice. It assumes an even greater significance in the current era of aggressive, industry-driven marketing. METHODS: A questionnaire was designed combining the McColl questionnaire and Barrier scale with relevant modifications and was administered to the urology trainees attending a continuing urological education program. Statistical analysis was performed using SPSS version 25. RESULTS: The meeting was attended by 110 urological trainees from 55 urological training centers all over India. One hundred and three of them agreed to participate in the study. About 92% of the questionnaires were fully completed. Less than half of the participants (47%) had access to reliable urological literature at work. Only 11% of the respondents claimed to have been formally trained in evidence-based urology (EBU). The inability to understand statistical analysis was the most common (67.4%) perceived barrier to EBU. CONCLUSION: The urological trainees in India are positively inclined towards EBU. The lack of formal training in appraising the available literature and lack of protected time, and portals to access the literature at workplaces hinder them from improving their compliance to EBU.

The Impact of Narrow Band Imaging in the Detection and Resection of Bladder Tumor in Transitional Cell Carcinoma of the Bladder: A Prospective, Blinded, Sequential Intervention Randomized Controlled Trial.

OBJECTIVE: To determine the impact of Narrow Band Imaging (NBI) in detection and resection of tumors during transurethral resection of bladder cancer. MATERIALS AND METHODS: This was a single center randomized prospective interventional study with a sequential intervention design. Patients with bladder tumors were randomized into 2 arms where they were resected under white light (WL) first followed by NBI in arm A, or NBI followed by WL in arm B. The number of patients in whom additional lesions were detected by the second light source, in both arms, was analyzed. The feasibility of initial resection of tumor under NBI was also studied. RESULTS: A total of 110 patients were randomized. Of 54 patients in arm A (WL first) additional lesions were identified at the second look in 20 patients (37%). In contrast, of 56 patients in arm B (NBI first), additional lesions were identified in 5(9%) patients. This difference of 28% was statistically significant (P value <.001). In arm B (NBI first), there were 7 breaches in protocol, and all these patients had high risk (more than or equal to 3 in number or 3 cm in size) tumors (P value <.002). CONCLUSION: Narrowband imaging is superior to WL in the detection of tumors, thus allowing a more complete resection. However, initial resection under NBI is difficult due to poor visibility, especially for high-risk tumors.

Synthesis, corrosion and wear of anodic oxide coatings on Ti-6Al-4V.

Electrodeposited anodic oxide coatings were produced on Ti-6Al-4V substrates using aqueous electrolytes containing dissolved calcium and phosphorus. Different coatings were produced by varying the time periods. The coatings were characterised by XRD technique and TEM. The coatings were exposed to Simulated Body Fluid (SBF). Electrochemical polarisation and ac impedance studies too were performed on the coatings in SBF. Pins were coated and run against wooden disc in pin-on-disc type of wear tests. Coatings produced from long time electrolysis showed very good resistance to the attack of SBF and less wear compared to those produced from short time exposure.
