European Association of Urology Section of Urolithiasis and International Alliance of Urolithiasis Joint Consensus on Retrograde Intrarenal Surgery for the Management of Renal Stones.

Background: Retrograde intrarenal surgery (RIRS) has become the preferred treatment modality for nephrolithiasis. However, because of ongoing uncertainties regarding the optimal perioperative management, operative technique, and postoperative follow-up, as well as a lack of standardization for outcome reporting, consensus is needed to achieve more uniform clinical practice worldwide.

Objective: To develop recommendations for RIRS on the basis of existing data and expert consensus.

Penile granulomas after BCG instillations. A case report and review of literature.

Penile granulomas has been rarely reported in the setting of BCG instillations. We present a 70 year-old male with multiple penile granulomas during BCG instillations due a high-grade urothelial bladder cancer.

[Laser in prostate cancer. Applicability.].

Objectives: In recent years, there has been a rise concerning the research and development of focal prostate cancer therapies as a consequence of the high percentage of low-risk and localized prostate cancers. These focal therapies aim at preserving the gland in selected patients to avoid overtreatment. The application of lasers for focal ablation and photodynamic therapy has shown promising results in exchange for a minimal rate of adverse events compared to radical treatments.
