Thulium Fiber Laser Enucleation of the Prostate: Prospective Study of Mid- and Long-Term Outcomes in 1328 Patients.

The objective of our study was to estimate the long-term efficacy and safety of thulium fiber laser enucleation of the prostate (ThuFLEP). We analyzed patients who underwent ThuFLEP due to lower urinary tract symptoms (LUTS) related to benign prostatic obstruction (BPO). Both the pre- and perioperative data as well as the follow-up data for 3 years were evaluated: prostate volume, postvoid residual (PVR), maximum flow rate (Qmax), International Prostate Symptom Score (IPSS), quality of life (QoL), prostate-specific antigen level, and the complication rate.

International Alliance of Urolithiasis (IAU) Guideline on percutaneous nephrolithotomy.

The International Alliance of Urolithiasis (IAU) would like to release the latest guideline on percutaneous nephrolithotomy (PCNL) and to provide a clinical framework for surgeons performing PCNLs. These recommendations were collected and appraised from a systematic review and assessment of the literature covering all aspects of PCNLs from the PubMed database between January 1, 1976, and July 31, 2021. Each generated recommendation was graded using a modified GRADE methodology.

Determination of Face and Content Validity of Cadaveric Model for Holmium Anatomic Endoscopic Enucleation of the Prostate Training: An ESUT AEEP Group Study.

Background: Bench and virtual reality nonbiological simulator models for anatomic endoscopic enucleation of the prostate (AEEP) surgery have been reported in the literature. These models are acceptable but have limited practical applications.

Objective: To validate a fresh-frozen human cadaver model for holmium AEEP training and assess its content validity.

The Impact of Lasers in Percutaneous Nephrolithotomy Outcomes: Results from a Systematic Review and Meta-Analysis of Randomized Comparative Trials.

Percutaneous nephrolithotomy (PCNL) is the first-choice treatment of renal stones larger than 2 cm. We aimed to evaluate if lasers perform as equal as non-laser devices in patients with kidney stones candidate to PCNL. A comprehensive literature search was performed in MEDLINE through PubMed, Scopus, and Cochrane Central Register of Controlled Trials (CENTRAL) to assess differences in the perioperative course, incidence of postoperative complications, and stone-free rate (SFR) in patients with kidney stones undergoing laser non-laser PCNL in randomized studies.

European Association of Urology Section of Urolithiasis and International Alliance of Urolithiasis Joint Consensus on Percutaneous Nephrolithotomy.

Context: Although percutaneous nephrolithotomy (PCNL) has been performed for decades and has gone through many refinements, there are still concerns regarding its more widespread utilization because of the long learning curve and the potential risk of severe complications. Many technical details are not included in the guidelines because of their nature and research protocol.

Objective: To achieve an expert consensus viewpoint on PCNL indications, preoperative patient preparation, surgical strategy, management and prevention of severe complications, postoperative management, and follow-up.

Efficacy of the Endoscopic Combined Intrarenal Surgery for the Treatment of a Staghorn Calculus in Crossed Fused Renal Ectopia.

Crossed fused renal ectopia (CFRE) is an unusual anomaly in which both kidneys lie fused on one side, with double pelvis and ureters draining into both sides of the bladder. Complex renal stones are a considerable challenge to endourologists, and when a staghorn stone is associated with abnormal anatomy, its treatment is even more difficult. Today there is no consensus about the right treatment for complex renal stones in CFRE.
