AI Article Synopsis

  • The study analyzed outcomes of 19 patients with symptomatic simple parenchymal and peripelvic kidney cysts who underwent retroperitoneoscopic cyst decortication between 1999 and 2004.
  • All patients had a mean age of 51 years, with symptoms like flank pain and hematuria, and the cysts varied in size from 8 to 15 cm.
  • Results showed successful procedures with no conversions needed, an average operative time of 70 minutes, minimal blood loss, and a short hospital stay, with all patients remaining asymptomatic during follow-up lasting up to 48 months.

Article Abstract

Introduction And Objective: The authors present the results and follow up of patients with simple parenchymal and peripelvic cysts who underwent retroperitoneoscopic cyst decortication.

Material And Methods: The records of 19 patients who underwent 3/4-port retroperitoneoscopic cyst decortication between January 1999 and January 2004 were retrospectively reviewed. All patients admitted to the hospital were symptomatic, the most common presenting syptoms were flank pain (19p) and hematuria (6p). The cyst size ranged from 8 to 15cm (mean size 10cm). 10 cysts were located on the right kidney and 9 cysts on the left kidney. The mean age of patients was 51 years. 16 patients had a simple parenchymal cyst corresponding to Bosniak type I (8 patients underwent cyst aspiration and sclerotherapy with 96 % alcohol in past), 2 patients had peripelvic cyst corresponding to Bosniak type II and 1 patient had a parenchymal cyst Bosniak type II.

Results: Retroperitoneoscopic renal cyst decortication was successfully performed in all patients, no conversion was needed. The mean operative time was 70 min (50-90 min) in patients with parenchymal and peripelvic cysts. The mean operative blood loss was 70 ml (50-130 ml) and the mean lenght of hospital stay was 3 days (2-5 days). The follow up ranged from 6 to 48 months and during that period were all patients asymptomatic, with no signs of recurrence.

Conclusions: Retroperitoneoscopic cyst decortication is a safe and effective operative procedure in the treatment of symptomatic renal cysts with the minimal complication rate and excellent results (Tab. 2, Fig. 3, Ref. 30).

: Retroperitoneal laparoscopic adrenalectomy (RLA) is one of two laparoscopic procedures used to treat benign and malignant adrenal diseases. Obesity in patients undergoing minimally invasive adrenal surgery is a frequently discussed topic. Our meta-analysis aimed to provide updated evidence by comparing intraoperative and perioperative outcomes on non-obese (NOb) and obese (Ob) patients who underwent RLA due to benign or malignant disease.

Objectives: To assess the feasibility of trial recruitment and confirm that retroperitoneal robotic partial nephrectomy (RRPN) has the same oncological efficacy as transperitoneal robotic partial nephrectomy (TRPN), with time advantages and less peri-operative morbidity, in a randomised controlled trial (RCT).

Patients And Methods: The study was designed as a single-centre, open-label, feasibility RCT. Patients with suspected localised renal cell carcinoma referred for robotic partial nephrectomy were randomised in a 1:1 ratio to receive either TRPN or RRPN.

The patient was a male in his 60s who underwent a retroperitoneoscopic right nephrectomy for a diagnosis of right renal cell carcinoma (cT3aN0M0). During surgery, the patient was positioned in the left lateral recumbent, jackknife position. A blood test of the day after surgery showed an abnormally high CK level of 23,038 U/L.

BACKGROUND Surgery involving the right retroperitoneum can result in lymphatic (chylous) leakage from the cisterna chyli located anterior to the L1 and L2 vertebra or from lymph node dissection. This report describes a 46-year-old woman with retroperitoneal lymphatic (chylous) leak following right adrenalectomy for a nonfunctional adrenal adenoma. CASE REPORT A 46-year-old woman presented with a medical history of hypertension.

Background: Investigating the application of single-port single-channel and single-port multi-channel adrenalectomy in various maximum tumor diameters.

Methods: Retrospective analysis of clinical data from 218 adrenal tumors treated with single-port retroperitoneoscopic adrenalectomy at Lianyungang Clinical Medical College of Nanjing Medical University from September 2018 to November 2023. All adrenal tumors are benign lesions classified as T1 stage.
