Retrovesical hydatid disease: a clinical study of 27 cases.
OBJECTIVE
We report our experience with 27 cases of retrovesical hydatid cysts (RVHC) and discuss the pathogenesis, diagnosis and treatment of this hydatid location.


METHODS
We retrospectively reviewed the clinical files of 27 patients with RVHC admitted to our institution from January 1984 to December 2000.


RESULTS
The predominant presenting symptom was burning micturition (13 cases). Physical examination revealed a pelvic mass in 17 patients. Preoperative diagnosis was based upon ultrasonography, intravenous pyelography, and serology tests. CT was performed in 10 patients. We noticed that RVHC can be subdivided into two categories: those that develop mainly in the peritoneal cavity (intraperitoneal type; 18 cases), and those that develop mainly in the confined pelvic cavity (subperitoneal type; 9 cases) and are more liable to induce ureteral compression and more difficult to approach surgically. One patient died before operation. Twenty-six patients were operated and had either a total (9 cases) or partial pericystectomy (17 cases). Four patients underwent closure of cystovesical fistulas. Two patients had ureteral reimplantation. Postoperatively, 1 patient died with septic shock and 1 was reoperated for peritonitis. Mean postoperative hospital stay was 8 days.


CONCLUSIONS
The preoperative diagnosis of RVHC is based mainly on ultrasonography. Open surgery is the treatment of choice.
