New study suggests patients with advanced prostate cancer on androgen deprivation therapy need more dialogue with health care provider, especially around cardiovascular risk
ConclusionThere is a need to enhance a constant patient –HCP dialogue, and both groups need to make a conscious effort in that direction. This would help in increasing patients’ awareness of risks, having better treatment choice and acceptance, and reducing side-effects. (Source: World Journal of Urology)

Treating benign ureteroenteric strictures: 27-year experience comparing endourological techniques with open surgical approach
AbstractPurposeTo compare open surgical anastomotic revision with endourological techniques for the treatment of ureteroenteric strictures in patients with urinary diversions.MethodsAll records of patients treated for ureteroenteric strictures in our clinic between 1989 and 2016 were retrospectively reviewed. In 76 patients, 161 completed procedures were analyzed: 26 open revisions vs. 135 endourological treatments, including balloon dilation, Wallstent and/or laser vaporization.ResultsMedian follow-up was 34  months. At 60 months, patency rates were 69% (95% CI 52–92%) after open vs. 27% (95% CI 19–3...

Novel laser positioning navigation to aid puncture during percutaneous nephrolithotomy: a preliminary report
AbstractPurposeAccurate puncture of the renal collecting system is crucial to the success of percutaneous nephrolithotomy and presents a technical challenge for urologists. Here, we introduced the Surgical Approach Visualization and Navigation (SAVN) system, a novel navigation system to assist puncture and reduce intraoperative radiation.Materials and methodsTwenty kidneys of 10 cadavers were randomly divided into two groups for renal calyx puncture. In the control group, traditional fluoroscopy was used for guidance, while SAVN system was used in the experimental group. Puncture duration, number of puncture attempts, tota...

En bloc re-resection of high-risk NMIBC after en bloc resection: results of a multicenter observational study
ConclusionsThe low rates of residual tumor, recurrence, and progression seem to raise doubts about the efficacy of EBRS in patients who have previously undergone en bloc resection. EBRS appears to be a feasible and safe procedure with a low rate of complications. However, further data will be needed before EBRS can be used in clinical trials or recommended as a treatment modality. (Source: World Journal of Urology)

Thermal effects of Ho:YAG laser lithotripsy during retrograde intrarenal surgery and percutaneous nephrolithotomy in an ex vivo porcine kidney model
ConclusionsHo:YAG laser lithotripsy bears the risk of thermal damages to the urinary tract even at low-power settings if inadequate irrigation is applied. Sufficient irrigation is mandatory to perform safe Ho:YAG laser lithotripsy. Based on the results, we developed a formula calculating the approximate ΔT for irrigation rates  ≥ 30 ml/min: ΔT = 15 K × (power [W]/irrigation [ml/min]). (Source: World Journal of Urology)
