Transmesentric laparoscopic unroofing of left simple renal cyst: a report of 12 cases

Abstract

Objective To investigate the method and efficacy of transmesentric laparoscopic unroofing of the left simple renal cyst. Methods The clinical data of 12 patients(4 males, 8 females) with left renal simple cyst treated by transmesentric laparoscopic unroofing were retrospectively analyzed.The mean age was 55 years(ranged 32~72). The mean diameter of the cases was 6.2 cm(ranged 4.8~8.6 cm). All the renal cysts were indicated by ultrosonography, CT scan and IVP.For each patient, the body mass index(BMI), blood loss, operative time, time to resumption of oral intake and complications, postoperative hospitalization days were recorded. Results All 27 cases of transemensetic laparoscopic unroofing renal cyst were successfully performed, without conversion to open surgery or serious intraoperative complications.Mean operative time was (36.3±11.6)min, and blood loss was (14.6±5.3)mL.The mean time of ambulation was 12h, and time of oral intake was 16h.The mean postoperative hospitalization time was (3.89±2.13)d.All the cases were assessed with ultrosonography and CT scan, no renal cyst recurrence was found during the follow-up of 3 months to 5 years. Conclusion Transmesentric laparoscopic unroofing of left simple renal cyst is a new and effective technique, which enables a shorter operation time without increasing morbidity, especially for slim patients.
