Percutaneous drainage with the injection of ethanol as the sclerosing agent for treatment of simple kidney cysts: A new modification.

J Endourol 2021 Apr 6. Epub 2021 Apr 6.

Tabriz University of Medical Sciences, 48432, Urology Department, Tabriz, East Azerbaijan, Iran (the Islamic Republic of);

Introduction: Simple kidney cysts are the most common type of benign kidney tumors in adults and they are usually asymptomatic. Symptomatic cysts are treated with percutaneous aspiration with or without sclerosing agent injection, laparoscopic decortication or with open surgery in rare cases. Considering the probable complications of anesthesia in open surgery and laparoscopic methods, we tend use an innovative method by percutaneous aspiration, inserting nephrostomy catheter for 24 hours and injection of sclerosing agents, leaving the agent inside the cyst while catheter is removed immediately.

BJU Int 2021 Mar 29. Epub 2021 Mar 29.

Department of Medical Oncology, Fox Chase Cancer Center, Philadelphia, PA, USA.

Objectives: To determine whether patients with carcinoma invading bladder muscle (MIBC) and ureteric obstruction can safely receive cisplatin-based neoadjuvant chemotherapy (C-NAC), and to determine whether such patients require relief of obstruction with a ureteric stent or percutaneous nephrostomy prior to beginning C-NAC.

Patients And Methods: We performed a single-institution retrospective analysis of MIBC patients receiving C-NAC and falling into three groups: no ureteric obstruction (NO); relieved ureteric obstruction (RO); and unrelieved ureteric obstruction (URO). To address whether patients with obstruction can safely receive C-NAC, we compared patients with NO to those with RO, with the primary outcome of premature chemotherapy discontinuation. Read More

Efficacy and safety of modified tract dilation technique using simultaneous pulling of proximal and distal ends of a guidewire for percutaneous nephrolithotomy in modified supine position.

Investig Clin Urol 2021 Mar;62(2):186-194

Department of Urology, School of Medicine, Kyungpook National University, Daegu, Korea.

Purpose: Recently, the needs for supine percutaneous nephrolithotomy (PCNL) have become more increased because of an easy approach for endoscopic combined intrarenal surgery. However, making a nephrostomy tract during supine PCNL is more difficult than prone position due to movable kidney. To overcome this limitation, we used a modified nephrostomy tract dilation (MTD) technique using guidewire traction. Read More

Semi-closed-circuit vacuum-assisted MiniPCNL system in pediatric patients.

J Pediatr Urol 2021 04 10;17(2):275-276. Epub 2021 Feb 10.

Urology Unit, Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico, University of Milan, Milan, Italy.

Surgical treatment of kidney stones has changed over the years. The use of Mini Percutaneous Nephrolithotomy (MiniPCNL) instrumentation is associated with a reduction of major complications but it lengthens the operative time (OT). This limit may be overcome by a semi-closed-circuit vacuum-assisted MiniPCNL system, characterized by a continuous inflow and a suction-controlled outflow. Read More
