Laparoscopic nephrectomy in a giant hydronephrotic nonfunctioning kidney occupying the most of the abdomen is challenging task. To overcome the difficulty in laparoscopic dissection of such kidneys we described a technique "Pneumorenum," wherein the kidney is decompressed by suction through a 5 mm trocar inserted directly into kidney under vision. Following suction decompression, the kidney is inflated later during dissection with carbon dioxide gas to moderate size to do the dissection in an easy manner.

Renorrhaphy is often performed after tumor resection during robotic-assisted laparoscopic partial nephrectomy (RAPN). This study aimed to investigate the association between renorrhaphy performance and inflammatory markers. A retrospective cohort study was conducted including patients with renal cell carcinoma who underwent RAPN at eight institutions in Japan between April 2016 and November 2023.

We present a case in which renal mixed epithelial and stromal tumor (MEST) was considered in the differential diagnosis based on preoperative imaging findings. A 38-year-old woman was found to have a right renal tumor during an abdominal ultrasound examination conducted as part of a health checkup. Contrast-enhanced computed tomography revealed a 50 × 40-mm mass in the middle of the right kidney.

Lumbar hernia (LH) is a rare abdominal wall hernia that occurs within the anatomic boundaries of the 12th rib, iliac crest, external oblique muscles, erector spinae muscles, and vertebral column. Secondary LH after urological surgery is rare, and the limited evidence hinders consensus on optimal surgical treatment. Here, we present a case of laparoscopic intraperitoneal onlay mesh (IPOM) repair for a large, symptomatic secondary LH after retroperitoneoscopic nephrectomy (RN) with mid-term postoperative outcomes.

Background: Standard postoperative care following laparoscopic radical nephrectomy (LRN) typically includes routine blood tests. Recent studies have assessed the safety of omitting routine postoperative labs in minimally invasive surgeries to reduce hospital costs. Our primary objective was to evaluate if routine postoperative day 1 (POD1) labs were necessary following LRN.

Primary renal epithelioid angiosarcoma (EAS) is extremely rare and carries a poor prognosis. Herein, we present a case of renal EAS in an 81-year-old male patient who complained of hematuria for 1 year. A computerized tomography (CT) scan revealed an occupying lesion at the upper pole of the left kidney, with scattered calcifications, along with retroperitoneal lymph node metastasis and possible lung metastasis.
