[Living-donor kidney graft ex vivo endoscopic nephrolithotomy with flexible instrument].

Introduction: The finding of an asymptomatic stone in the study of a living kidney donor does not necessarily contraindicate donation, however, there is no consensus on the management of these cases. The use of a graft with lithiasis may represent a risk of recurrence in the remaining kidney in the donor and eventual obstructive complications in the transplanted kidney. The objective of this work is to present the usefulness of ureteroscopy (URS) to resolve lithiasis ex vivo before transplantation.

Defining bladder outlet obstruction and detrusor underactivity in females with overactive bladder: Are we forgetting about the free uroflowmetry?

Introduction: Both detrusor underactivity (DU) and bladder outlet obstruction (BOO) can coexist in patients with overactive bladder. Definitions of both DU and BOO are based on pressure-flow study (PFS) data. However, invasive urodynamics study can differ from a natural micturition, in fact, discrepancies between free uroflowmetry (UFM) and PFS have been largely described.

[Prognostic factors in patients with upper urinary tract urothelial carcinoma undergoing nephro-ureterectomy].

Background: Upper urinary tract urothelial carcinoma (UTUC) represents 5-10% of urothelial carcinomas. It is managed with nephroureterectomy (NUR); however, kidney-sparing techniques are growingly used.

Aim: To report the results of a 20-year series of NUR conducted in an academic center.

Intrarenal temperature measurement associated with holmium laser intracorporeal lithotripsy in an ex vivo model.

Introduction: The aim of this article was to quantify the effect of the use of holmium laser during intracorporeal lithotripsy in an ex vivo model.

Material And Methods: A simulated model for laser nephro-lithotripsy was designed. Two ex vivo porcine kidneys were used.

Protective role of intravesical BCG in COVID-19 severity.

Objectives: To establish the role of BCG instillations in the incidence and mortality of COVID-19.

Patients And Methods: NMIBC patients in instillations with BCG (induction or maintenance) during 2019/2020 were included, establishing a COVID-19 group (with a diagnosis according to the national registry) and a control group (NO-COVID). The cumulative incidence (cases/total patients) and the case fatality rate (deaths/cases) were established, and compared with the national statistics for the same age group.

Successful unilateral vasectomy reversal in a lion ().

Background: In 2016, the veterinarian team of Buin Zoo in Chile decided to try to increase the lion population. At that time, the zoo had three lions; two females and one male. The 9-year-old male had been vasectomized 5 years ago at the same institution for birth control.

Subcapsular Renal-Infected Hematoma After Retrograde Intrarenal Surgery: A Rare but Serious Complication.

We report a case of a 53-year-old woman affected by a left kidney stone and persistent positive urinary culture treated by retrograde intrarenal surgery. During postoperative day 1, she developed a sudden back pain associated with a decrease in hemoglobin. CT scan showed a subcapsular hematoma giving the impression of partial compression of kidney and upper urinary tract.

[Shock wave lithotripsy, retrograde intrarenal surgery or percutaneous nephrolithotomy for lower pole renal stones?].

Among the therapeutic alternatives available for the treatment of lower pole renal calculi are extracorporeal lithotripsy, percutaneous nephrolithotomy and retrograde intrarenal surgery. There is controversy about which of these techniques is more effective, especially for stones smaller than 20 mm. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified four systematic reviews including 11 pertinent randomized controlled trials overall.
