Renal cysts are a common disease that occurs at a rate of 7-10%. Currently there are no guidelines for the treatment of patients with simple renal cysts. It is relevant to explore a minimally invasive, safe, and cost-effective method of treatment to provide a shorter bed-day and a high level of patient satisfaction. The aim of the study is to analyze the efficacy and safety of drainless modification of laparoscopic deroofing of renal cyst.

A retrospective study was conducted to include 904 patients who underwent laparoscopic treatment of renal cysts by drainless technique between 2012 and 2023. Treatment was performed using a fast-track protocol, with discharge from the hospital the day after surgery.

The mean age of the patients was 61.27±14.45 years. The average cyst size was 83.94 mm (201; 58). The mean operative time was 51 ± 14.2 min (24-80 min). The average volume of blood loss was less than 10 ml, drop of hemoglobin by an average of 5 units. The urethral catheter was removed on the day of surgery, and early activation was performed (6-8 h after surgery). The average VAS score was 1.4 points (0 to 3 points). The need for analgesia was noted in 13.3% (128 patients). 1 patient with pain syndrome underwent CT scan (0.1%), hematoma up to 200 ml was detected, no additional interventions were required. He was discharged on the 4th day. The average hospital stay was 1.2 days, and more than 95% of patients were discharged from the hospital on the 1st day after surgery.

Laparoscopic deroofing of renal cysts is an effective and safe method and can be used in a same-day surgery mode. The introduction of the drainless modification of the operation will provide a higher level of patient satisfaction, increase economic efficiency and reduce hospital stay.
