Introduction: Medical expulsive therapy (MET) has been shown to be a safe and effective option for the spontaneous passage of uncomplicated ureteric stones sizing ⩽10 mm in selected cases. However, there is lack of evidence on the predictors of successful MET. Our objective was to identify parameters that can accurately predict the spontaneous passage of ureteral stones during MET.

Introduction: To compare the efficacy and safety of extended lymph node dissection (eLND) versus standard LND (sLND) in patients with bladder cancer undergoing radical cystectomy, focusing on overall survival (OS), recurrence-free survival (RFS), and complications, including symptomatic lymphoceles.

Materials And Methods: A systematic review and meta-analysis were conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched PubMed, MEDLINE, Embase, Scopus, and Cochrane databases for randomized controlled trials (RCTs) comparing eLND and sLND.

Objective: To evaluate the outcomes of dorsal onlay labial mucosal graft urethroplasty in female urethral stricture (FUS), a condition that remains challenging and frequently underdiagnosed due to nonspecific symptoms and diagnostic limitations.

Methods: A retrospective analysis of a prospectively maintained database was conducted, including 204 patients who underwent dorsal onlay labial mucosal graft urethroplasty for FUS between June 2013 and July 2024. Patients were included if they had symptomatic FUS confirmed by uroflowmetry, micturating cystourethrogram, or urethral calibration.

Background And Objective: Prostate biopsy, conducted frequently through the transrectal route, is associated with significant risks of infectious complications. This study aimed to compare the efficacy of various strategies to reduce these complications, using a network meta-analysis approach.

Methods: Our study included randomized controlled trials (RCTs) identified from PubMed/MEDLINE, Embase, and the Cochrane database as of March 1, 2024.

Introduction: Traction on the per-urethral catheter is commonly employed after monopolar transurethral resection of the prostate (mTURP) to reduce bleeding. However, its efficacy and impact on postoperative pain remain uncertain. Further, there is limited evidence to suggest any benefit regarding post-operative blood loss.

Objective: To determine the impact of radical local treatment (RLT) on overall survival (OS) and other survival outcomes in patients with OligoMetastatic Prostate Cancer (OMPC).

Methods: We performed a meta-analysis of randomized controlled trials (RCTs) published in the MEDLINE and CENTRAL databases until May 2023. We included RCTs that randomized patients to RLT (either radical prostatectomy [RP] or external beam radiotherapy [EBRT]) and standard of care and reported on OMPC.

Introduction: This meta-analysis compares the clinical outcomes of robot-assisted kidney transplant (RAKT) to open kidney transplant (OKT).

Methods: A systematic search of Scopus and MEDLINE databases was carried out using a combination of keywords to identify studies comparing RAKT to OKT. Baseline characteristics and preoperative and postoperative data were collected along with data on the short- and long-term outcomes.

Introduction: The majority of the open access publishing allows the researchers to publish their articles for a fee and at the same time enables the readers to access the research without paying the expensive journal subscription charges. Under the garb of open access publishing, predatory journals run a scam to dupe the researchers of money. This study was conducted to highlight the characteristics of pseudojournals and increase the awareness about their modus operandi.

Background: To find the impact of the obstructive index (OI) as a predictor of management in antenatal pelviureteric junction obstruction.

Methods: Records of 135 cases of antenatally detected unilateral pelviureteric junction obstruction, selected for initial observation were retrospectively analyzed. All patients who underwent pyeloplasty on follow up were assigned to Group A.

Objective: Despite conflicting evidence, it is common practice to use continuous antibiotic prophylaxis (CAP) in patients with indwelling double-J (DJ) stents. Cranberry extracts and d-mannose have been shown to prevent colonization of the urinary tract. We evaluated their role in this setting.

Objective: With the advent of laparoscopic approach for the large (T1b-T3a ± N1) right renal masses, higher rates of complications and conversion to open surgery are being reported. The role of preoperative angioembolization (PAE), which has increased cost and inherent morbidity but may help in select circumstances has also not been clearly defined in the literature. We therefore devised a scoring system (SGPGI score) based on pre-operative Computed Tomography Angiography (CTA) to predict the level of difficulty of radical nephrectomy and enhance its safety and efficacy which could also be used for the judicious use of PAE in selected cases.

Objective: To evaluate the efficacy and safety of supracostal percutaneous nephrolithotomy (PCNL) through the 11th intercostal space and compare it with subcostal PCNL in children with renal calculi.

Materials And Methods: Children with renal calculi who underwent PCNL between January 2010 and December 2017 were divided into 2 groups: supracostal PCNL (group 1) and subcostal PCNL (group 2). Stone location, stone burden, location of the access points, operative time, postoperative visual pain score, success rate, hospital stay, and complications according to the modified Clavien classification were compared.

Background: Despite technological advancements, there is lack of consensus for the standard treatment modalities for pediatric urolithiasis.

Objective: The primary objective was to review the management of pediatric urolithiasis over the last 15 years in terms of technical modifications, surgical outcomes, and complications. The secondary objective was to compare the efficacy and outcomes of standard percutaneous nephrolithotomy (PCNL) and mini-PCNL for renal and upper ureteric calculi.

Introduction: Percutaneous nephrolithotomy (PCNL) for stones in solitary kidney poses a significant challenge and potential threat for acute kidney injury or progression of chronic kidney disease (CKD). We present our experience of PCNL in solitary functioning kidney (SFK) to evaluate the safety, efficacy, and postoperative complications and highlight the differences between these outcomes with respect to the stage of CKD.

Methods: We carried out a retrospective study of patients with SFK, who underwent PCNL at our center from April 2010 to March 2018.

Introduction: We present the short-term voiding patterns and functional and urodynamic outcomes of W-shaped ileal orthotopic neobladder (ONB) following radical cystectomy (RC).

Materials And Methods: Forty-one patients who underwent RC and W-shaped ONB creation between July 2015 and January 2018 were enrolled. Data were analyzed in terms of voiding patterns, urodynamic findings, and functional outcomes at 6 months after surgery.

Objective: To evaluate the factors predicting the risk for failed angiographic management (AM), we retrospectively studied cases of digital subtraction angiography (DSA) and superselective angiography (SSA) to control severe/delayed bleeding following renal interventions, which may otherwise be life threatening and often require nephrectomy.

Methods: We have retrospectively evaluated the data of 154 patients who underwent DSA and or SSA during January 2006 to June 2016. Twenty-one patients (Group A) with failed AM were compared to patients with success AM (n = 133, Group B).
