Laparoscopic Treatment of the Isolated Renal Hydatid Cyst: Long-Term Outcomes from a Single Institution

Abstract

Objective: To determine the effectiveness of treatment via laparoscopic approach and to present the long-term outcomes in patients with isolated renal hydatid cyst. Materials and Methods: We reviewed the data of 11 patients who underwent laparoscopic treatment for isolated renal hydatid cyst between March 2004 and January 2017. Demographic characteristics and clinical, laboratory, and radiological findings of cases were examined. Mann-Whitney U and t-test were used in statistical analysis. Results: The mean age of the patients was 36.7 years (25-51). The common complaint of the patients was lumbar pain and 9 patients had a palpable mass. It was identified that serologic evaluation of Echinococcus granulosus was positive in 5 patients. The mean cyst size was determined as 72mm (40-150). The mean operation time was 128 minutes (120-150) while the length of hospital stay was 4 days (3-13). Perioperative major complication was not observed in any of the patients. The levels of hematocrit and creatinine were measured, 37.8 (26-43) and 0.93 (0.5-1.3), respectively, in the postoperative period, while these levels were 39 (26-45) and 0.90 (0.5-1.3) in the preoperative period and there was no statistically significant difference (P>.05). The mean follow-up time was 84 months (40-166). No relapses were observed in any patients. Conclusions: The treatment of renal hydatid cyst disease with laparoscopic approach is a safe and effective method. There was no recurrence in any of the patients in the long-term period. Further studies including a large series of patients are needed.
