Article Synopsis
- Aim: The study investigates how cystatin C levels change in patients after laparoscopic and retroperitoneoscopic procedures involving retroperitoneal organs.
- Methods: It involved 162 patients with renal cysts who were categorized based on procedure duration and gas levels, using flow cytometry to measure cystatin C in serum and urine.
- Results: Elevated cystatin C levels were observed after laparoscopic procedures with higher gas pressures; levels returned to normal by day 3, highlighting gas pressure and procedure duration as key risk factors for kidney injury.

Background: Retroperitoneal robotic-assisted laparoscopic pyeloplasty (R-RALP) for ureteropelvic junction obstruction (UPJO) has gained growing acceptance among pediatric urologists, and is increasingly performed as day-case surgery, involving smaller children and infants. However, retroperitoneal CO insufflation may cause hemodynamic derangements, respiratory changes, and hypercapnia, whose consequences are poorly investigated. We, therefore, decided to prospectively study its effect on regional tissue perfusion and oxygenation in a cohort of pediatric patients undergoing R-RALP, using a dedicated anesthetic protocol and cerebral and renal Near InfraRed Spectroscopy (NIRS).

To determine the effects of carbon dioxide insufflation on renal function in a pneumoretroperitoneum model, 24 adult New Zealand rabbits were divided into four groups, six rabbits in each. The first group underwent a 2-hour CO2 insufflation at a pressure of 10 mm Hg in the retroperitoneal space after balloon dissection. In another group, the same procedure was maintained for 4 hours.

Probl Endokrinol (Mosk)
January 1990
The paper is devoted to the use of a new method of nuclear magnetic resonance tomography (MR tomography) in the diagnosis of diseases of the adrenal glands developing with the syndrome of total and partial hypercorticism. A MR tomograph with resistive magnet (0.234 T) was employed.
