Primary retrovesical hydatidosis causing chronic renal failure

Prevesical hydatid cyst: A case report

Hydatid cyst is a zoonotic disease caused by a tapeworm of the genus Echinococcus granulosus either in its adult or larval forms. Original pelvic cysts are rare; however, the majority of abdominal and pelvic hydatid cysts are believed to result from inadvertent surgical inoculation or spontaneous rupture from a primary hepatic focus. We present a 35-year-old female patient who visited our facility complaining of lower abdominal pain that had persisted for the last 5 months.

Total laparoscopic management of a large renal hydatid cyst by using hydatid trocar cannula system

Renal hydatidosis usually requires surgical treatment such as pericystectomy, marsupialization, or nephrectomy. In the era of minimally invasive surgery, laparoscopic treatment is preferred. Two main challenges in laparoscopy are to avoid the spillage of contents and to minimize incision for delivering the specimen. We herein discuss the use of a hydatid trocar cannula system (HTCS) to overcome these problems. A 46-year-old male patient having a large renal hydatid cyst (18×15 cm) was operated using HTCS. Three standard laparoscopic ports were placed and the HTCS was placed from the fourth port (18 mm). After aspiration of contents, the cyst was inspected using laparoscope and all contents were sucked. The operation time was 120 min and the total blood loss was around 100 ml. No intraoperative spillage was noted. The patient was orally allowed on Day 2 and discharged on Day 3. Oral albendazole therapy was continued 3 months after the operation. He remained symptom free and abdominal computed tomography did not reveal any recurrences during a follow-up of 2 years. Use of HTCS in renal hydatidosis not only prevents the spillage of hydatid fluid, but also assists in the complete evacuation of contents and allows intracystic visualization to check complete removal of scolices.

Isolated renal hydatid cyst managed by laparoscopic transperitoneal nephrectomy

Hydatid disease is a cyclozoonotic parasitic infestation caused by the cestode Echinococcus granulosus. Isolated renal involvement is extremely rare. A 45-year-old female, working as a farmer, presented with vague abdominal pain and hydatiduria. Ultrasonography of the abdomen revealed hydatid cyst arising from the right kidney. Computerized tomography scan of the abdomen confirmed the findings. Laparoscopic transperitoneal nephrectomy was performed. Isolated right renal hydatid cyst was removed in toto. Microscopic examination confirmed the diagnosis of hydatid cyst. Transperitoneal laparoscopic approach gives a better working space which helped us to remain outside Gerota's fascia and prevent subsequent cyst rupture.

[Giant retroperitoneal hydatid cyst]

Hydatidosis is an endemic, widely distributed anthropozoonosis, which involves the liver, lung and other organs [Int J Urol 13 (2006) 76-9]. We reported the case of a large retroperitoneal hydatid cyst, which is a rare situation [Hepatogastroenterology 48 (2001) 1037-9; Int Urol Nephrol 32 (2000) 41-6; J Urol (Paris) 94 (1988) 445-8]. Diagnosis was suspected with blood tests and radiological examinations. A wide incision in the right iliac fossa (such in renal graft) was performed. The cyst wall was excised partially. Before, during and following the operation, the patient was given albendazole tablets (15mg/kg per day) for 3 weeks (1 week before and 2 weeks after the surgery) with blood count and liver enzyme monitorization. Especially in the endemic areas, hydatid cyst should be remembered when evaluating cystic masses in the retroperitoneum. It can be treated successfully with surgery.

An unusual cause of obstructive uropathy: primary retrovesical hydatid cyst

The incidence of hydatid disease in genitourinary system is very low and isolated involvement in retrovesical region is rare [1-3]. Here is a report of a case of retrovesical hydatid cyst leading to obstructive uropathy with successful outcome.
