Learning curve of semi-rigid ureteroscopy for small calculi: how many cases are necessary?

Introduction: semi-rigid ureteroscopy is the procedure of choice for the treatment of ureterolithiasis, but it requires a learning curve to be performed safely.

Objective: To describe an estimate of the learning curve for performing semi-rigid ureterorenolithotripsy in patients with small-sized ureterolithiasis and to estimate the minimum number of procedures necessary to safely perform the surgical procedure.

Methods: this is a prospective study evaluating the learning curve of a resident of urology in the first 60 semirigid ureteroscopies in patients with ureterolithiasis up to 1cm.

Digital application developed to evaluate functional results following robot-assisted radical prostatectomy: App for prostate cancer.

Introduction: Mobile applications ("apps") developed for smartphones and tablets are increasingly used in healthcare, allowing remote patient support or promoting self-health care. Prostate cancer (PC) screening allows for early-stage PC diagnosis, resulting in high rates of curative procedures such as radical prostatectomy. The main complications following surgery are urinary incontinence and erectile dysfunction.

HIV-associated multicentric Castleman's disease.

Multicentric Castleman's disease (MCD) is a rare lymphoproliferative disorder. It is found with higher frequency in patients with HIV infection, with systemic symptoms and poor prognosis. We present the case of a 32-year old man with HIV disease, Kaposi's sarcoma, lymphadenopathy, fever and hemolytic anemia.
