Retroperitoneal Laparoscopy Deroofing for Parapelvic Cyst:Report of 16 Cases / 中国微创外科杂志

ABSTRACT

Objective To explore the efficacy of retroperitoneal laparoscopy in the treatment of parapelvic cyst.Methods From August 2005 to December 2008,16 cases of parapelvic cyst were treated by retroperitoneal laparoscopic deroofing and decompressing in our hospital.Under general anaesthesia,an operational space was established via retroperitoneal route.And then,along the urethra,the parapelvic cyst was explored.Afterwards,the cyst was unroofed 3 to 5 mm from the normal renal tissues.Results The operation was completed in 15 of the patients with a mean operation time of(75?20) minutes and mean blood loss of(28?8) ml.No injuries to the kidney pedicle or pelvis occurred.Another patient was converted to open surgery because of difficulty in exposure of the cyst.This series were followed up for a mean of 13 months(range,6 to 20 months).No one had recurrence during the period.Conclusions Retroperitoneal laparoscopic deroofing is minimally invasive,safe and effective or parapelvic cyst.It should be the first choice for the disease.
