BACKGROUND: The Post-ureteroscopic Lesion Scale (PULS) was designed as a standardized classification system for ureteral lesions after uretero(reno)scopy (URS). This study evaluates its routine use and a possible clinical impact based on a representative patient cohort. MATERIALS AND METHODS: Data of 307 patients in 14 German centers within the BUSTER project were used to test 3 hypotheses (H): PULS score shows a high interrater reliability (IRR) after independent assessment by urologic surgeon and assistance personnel (H1); PULS score is correlated with the frequency of postoperative complications during hospital stay (H2); post-URS stenting of the ureter is associated with higher PULS scores (H3)...

PURPOSE: Transurethral lithotripsy (TUL) is a major modality for the endoscopic management of ureteral stones. Ureteral spasm makes access for ureters difficult, which causes impaction of the ureteroscope, ureteral dislodge, and a low success rate of endoscopic surgeries. This study described the outcomes of a new endoscopic surgical experience by use of 40-degree warm saline irrigation during TUL compaired with routine ambient air irrigation in TUL. MATERIALS AND METHODS: In this randomized clinical trial from 2014 to 2015, 150 patients with ureteral stone with balanced randomization were divided into two parallel groups...

Extracorporeal shock wave lithotripsy can cause pain and anxiety for patients. Despite the use of many distraction methods to reduce pain and anxiety, there is no study on the use of stress balls during lithotripsy. The aim of the study was to investigate the efficacy of use of stress balls and music therapy to reduce pain and anxiety during lithotripsy. This was a single-center, parallel randomized controlled trial. The study involved the lithotripsy unit in a training and research hospital in Turkey. The study included 120 patients who had kidney or ureter stones...

REVIEW
José Manuel Reis Santos
Stone surgery is one of oldest surgical practices undertaken by man. Hippocrates refused to let his followers "cut for the stone" and it was only in February 1980, when the first human trial of shock wave therapy on a renal stone was performed with success that a new era in minimally invasive treatment (surgery) for stones was opened up and this condemnation was finally resolved in the Hippocratic Oath. Endoscopy, using natural orifices, supported by anaesthesia, incremented by technology and with access to all points along the urinary tract, began by competing with ESWL, but is now the treatment of choice in most cases...

Background: Nephron-sparing surgery has been shown to achieve oncological results equivalent to those of radical nephrectomy in patients with compromised renal function who have renal tumors <4 cm. However, technical difficulties and potential surgical complications remain challenges to the surgeon. Various factors, such as tumor size and location, collecting system invasion, and patient's expectations, are major concerns that may affect the feasibility of performing an effective partial nephrectomy. We report a patient with renal cell carcinoma who underwent open partial nephrectomy and suffered from complications of perirenal abscess because of stone migration, obstruction, and subsequence urine leakage...

Introduction: Flexible ureteroscopy (fURS) is an endoscopic procedure for the minimally invasive treatment of ureteral and renal calculi. Due to improvements in technique and ureteroscopic instrumentation over the past two decades, complications associated with URS are infrequent. However, in the event of an unexpected device malfunction or failure, the operating surgeon must employ prompt, resolute decision-making to resolve any intraoperative complications and avoid significant injury to the kidney or ureter...
