Context: De Novo nephrolithiasis in renal transplant can have severe consequences since renal transplantation involves a single functioning kidney with medical and anatomical specificities (heterotopic transplantation on iliac vessels, immunosuppressive treatments, and comorbidities).

Objective: To systematically review all available evidence on the prevalence of de novo nephrolithiasis in renal transplant, presentation, and stone characteristics, and to report in a meta-analysis the efficacy of stone treatments (extracorporeal shock wave lithotripsy [ESWL], medical treatment, percutaneous nephrolithotomy [PCNL], open surgery, and ureteroscopy).

Evidence Acquisition: Medline, Embase, and the Cochrane Library were searched up to November 2021 for all relevant publications reporting the management of de novo nephrolithiasis in renal allografts.

Context: There is uncertainty regarding the most appropriate criteria for recruitment, monitoring, and reclassification in active surveillance (AS) protocols for localised prostate cancer (PCa).

Objective: To perform a qualitative systematic review (SR) to issue recommendations regarding inclusion of intermediate-risk disease, biopsy characteristics at inclusion and monitoring, and repeat biopsy strategy.

Evidence Acquisition: A protocol-driven, Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA)-adhering SR incorporating AS protocols published from January 1990 to October 2020 was performed.

Context: While the management of bladder outlet obstruction (BOO) in men has been a topic of several systematic reviews and meta-analyses, no such evidence base exists for female BOO.

Objective: The aim of this systematic review was to evaluate the benefits and harms of therapeutic interventions for the management of BOO in women.

Evidence Acquisition: This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement.

The role of Testosterone Therapy (TTh) in the management of male sexual dysfunction remains unclear. Objective of the authors was to systematically review the relevant literature assessing the benefits and harms of TTh in men with sexual dysfunction. EMBASE, MEDLINE, Cochrane Systematic Reviews-Cochrane Central Register of Controlled Trials (CENTRAL) (Cochrane HTA, DARE, HEED), Google Scholar, WHO international Clinical Trials Registry Platform Search Portal, CINAHL databases and clinicaltrial.

Context: Kidney transplantation is the best treatment for patients with end-stage renal disease. Incidence of small renal masses (SRMs), which most frequently are renal cell carcinomas (RCCs), is highest in patients aged >60 yr. The increasing age of donors can lead to the diagnosis of a higher number of SRMs when assessing the patient for transplantation, and so can theoretically decrease the number of kidneys suitable for transplantation.

Context: The oncological efficacy of routine lymphadenectomy (lymph node dissection [LND]) at the time of radical nephroureterectomy (RNU) remains controversial.

Objective: To systematically review the available literature assessing the impact of LND in upper tract urothelial carcinoma (UTUC) patients.

Evidence Acquisition: Embase, Medline, and Cochrane databases were searched for all studies comparing outcomes of patients undergoing RNU without LND versus any form of LND.

Context: Most series have suggested better perioperative outcomes of laparoscopic radical nephroureterectomy (RNU) over open RNU. However, the oncological safety of laparoscopic RNU remains controversial.

Objective: To systematically review all relevant literature comparing oncological outcomes of open versus laparoscopic RNU.

Context: Renal transplantation is the gold standard renal replacement therapy in end-stage renal disease owing to its superior survival and quality of life compared with dialysis. When the potential recipient has a history of cancer, the waiting period before renal transplantation is usually based on the Cincinnati Registry.

Objective: To systematically review all available evidence on the risk of cancer recurrence in end-stage renal disease patients with a history of urological cancer.

Context: Current evidence-based management for clinically localised prostate cancer includes active surveillance, surgery, external beam radiotherapy (EBRT) and brachytherapy. The impact of these treatment modalities on quality of life (QoL) is uncertain.

Objective: To systematically review comparative studies investigating disease-specific QoL outcomes as assessed by validated cancer-specific patient-reported outcome measures with at least 1 yr of follow-up after primary treatment for clinically localised prostate cancer.

Unlabelled: People with asymptomatic bacteriuria (ABU) are often unnecessarily treated with antibiotics risking adverse effects and antimicrobial resistance. We performed a systematic review to determine any benefits and harms of treating ABU in particular patient groups. Relevant databases were searched and eligible trials were assessed for risk-of-bias and Grading of Recommendations, Assessment, Development and Education quality.

Context: Extracorporeal shock wave lithotripsy (SWL) and ureteroscopy (URS), with or without intracorporeal lithotripsy, are the most common treatments for upper ureteric stones. With advances in technology, it is unclear which treatment is most effective and/or safest.

Objective: To systematically review literature reporting benefits and harms of SWL and URS in the management of upper ureteric stones.

Context: It remains unclear whether patients with a suspicion of prostate cancer (PCa) and negative multiparametric magnetic resonance imaging (mpMRI) can safely obviate prostate biopsy.

Objective: To systematically review the literature assessing the negative predictive value (NPV) of mpMRI in patients with a suspicion of PCa.

Evidence Acquisition: The Embase, Medline, and Cochrane databases were searched up to February 2016.

Context: There is controversy regarding the therapeutic role of pelvic lymph node dissection (PLND) in patients undergoing radical prostatectomy for prostate cancer (PCa).

Objective: To systematically review the relevant literature assessing the relative benefits and harms of PLND for oncological and non-oncological outcomes in patients undergoing radical prostatectomy for PCa.

Evidence Acquisition: MEDLINE, MEDLINE In-Process, Embase, and the Cochrane Central Register of Controlled Trials were searched up to December 2015.

Context: There is uncertainty regarding the oncologic effectiveness of kidney-sparing surgery (KSS) compared with radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC).

Objective: To systematically review the current literature comparing oncologic outcomes of KSS versus RNU for UTUC.

Evidence Acquisition: A computerised bibliographic search of the Medline, Embase, and Cochrane databases was performed for all studies reporting comparative oncologic outcomes of KSS versus RNU.
