Retrovesical hydatic cyst : About 4 cases
Keywords:Retrovesical hydatid cyst, Diagnosis, Surgery.
Introduction: The hydatid cyst is a real public health problem in Tunisia. The retrovesical localization is rare. It is considered an aberrant or ectopic location defined by the development of the parasite in the subvesical and retrovesical fat.
Methods: From 2004 to 2013, 4 patients with retrovesical hydatid cyst were hospitalized and operated in the Department of Urology at the Charles Nicolle hospital of Tunis in Tunisia. The average patient age was 40.75 years (range: 23 –76). Signs of bladder irritation were the most frequent presenting complaint. No cases of hydaturia were noted. The diagnosis was made on the ultrasound and the computed tomographic urography. Hydatid serology was positive for 3 patients. In 3 cases, a hydatid cyst of the liver was associated. A total cysto-pericystectomy was performed for 1 patient, for others it was partial.
Results: The postoperative course was uneventful. No urinary fistula or infection of the residual cavity was observed. One patient had a retroperitoneal cyst recurrence requiring reoperation.
Conclusion: Retrovesical location of hydatid cyst is rare and treatment is primarily surgical.
