Laparoscopy by retroperitoneal access for the treatment of parapelvic cyst / 中华泌尿外科杂志

ABSTRACT

Objective To evaluate the minimally invasive technique of laparoscopy by retroperitoneal access for the treatment of parapelvic cyst. Methods Twelve patients(7 men and 5 women;mean age,52 years;age range,34-75 years) with parapelvic cysts were included.The cyst size ranged from 2.8 cm?3.0 cm to 2.5 cm?11.5 cm.The cysts were on the left side in 6 cases and on the right in another 6 cases.Laparoscopic resection or de-roofing of the parapelvic cysts by retroperitoneal access was performed in them.The relevant parameters of the procedures were summarized.Results The success rate of the operation was 100%.The mean operative time of the first 6 patients was 190 min,while it was 86 min in the rest 6 patients.The mean intraoperative blood loss was 25 ml.No injury to the kidney pedicle or pelvis occurred.The mean hospital stay was 9 d.In 11 patients,no recurrence of the cyst occurred during a follow-up of 7-31 months.Only 1 patient with concomitant renal cyst had recurrence of the cyst found by B-ultrasound 2 years after operation.Conclusions Therapeutic laparoscopy by retroperitoneal access has advantages of minimal trauma,less blood loss,rapid recovery and better effect,therefore it is the ideal treatment choice for parapelvic cyst.
