hydatid cyst of urinary bladder

My stay in the Urology Unit of Necker's hospital in my last year of residency in 1960 was a decisive turning point in my career. My training as resident in the urologic department was planned for one half year, however it was extended to five half years of clinicat, after that professor Couvelaire invited me to participate to a competitive exam of professor in urology which held in December 1962. The medical school of Algiers, the only known active institution in Maghreb, planned an appointment of urologic surgeon...

Echinococcal cysts usually involve the liver; extrahepatic localization is reported in 11% of all cases of abdominal hydatid disease. We report a case of a prevesical hydatid cyst. A 53-year-old man was admitted with a large suprapubic mass. Ultrasonography and computed tomography revealed a cystic mass situated in front of the urinary bladder. There were no cysts in any other location. Serological tests were positive for Echinococcus. The patient was operated on and the cyst was completely excised. The pathologic examination confirmed the diagnosis of Echinococcosis...

We present a patient with symptoms of abdominal pain and frequent urination due to a huge mass in the retrovesical region. All imaging modalities revealed a cystic mass containing small daughter cysts located between the urinary bladder and rectum. Its characteristics led us to suspect the presence of a hydatid cyst, and an indirect hemagglutination test for Echinococcus granulosus was found positive. No other involvement of hydatid cystic disease was detected. The primary site for the hydatid disease was therefore regarded as the pelvis, on which only a few cases have been reported previously...

Retrovesical hydatid cyst is rare, even in endemic regions. From a presentation of three cases, the authors will review the clinical findings and illustrate the imaging features of this pathology and relate diagnostic and therapeutic difficulties.

Our case concerns 66-year-old female with a multiple unusual locations of hydatid cysts including bladder, psoas muscle and liver. Coexistence of hydatid cysts in these localizations has not been previously reported. The diagnosis of vesical hydatid cyst was facilitated by the coexistence of other echinococcosis locations. Treatment consists of the excision of the cysts in the same session without any postoperative anthelmintic drugs. In a two-year follow-up no recurrence has occurred.

A case of intraprostatic cyst is reported. The patient presented with a completely evacuated hydatid cyst of the prostate. The intraprostatic cystic cavity that was communicating with the urethra developed urinary stones. The patient had transurethral resection of the prostate, the stones in the cyst were pushed into the bladder and fragmented using a ballistic lithotripter. Pathological examination concluded to a prostatic hydatid cyst that had evacuated through the urethra and was complicated by stone formation within the residual cavity...

Hydatid disease mainly affects the liver and the lungs. Pelvic involvement have been rarely reported in the literature. Herein we present a rare case of isolated hydatid cyst of pelvis attached to the urinary bladder.

A case of intravesical hydatid cyst is reported. The cyst was completely evacuated cystoscopically with intravesical instillation of a scolicidal agent (hydrogen peroxide) to destroy scolices and daughter cysts. The postoperative course was uneventful, and follow-up did not show evidence of recurrence. Because this is the first case, to our knowledge, to be reported, little is known about the nonoperative management of such hydatid localization. A recommendation is made, however, to adopt this minimally invasive procedure...

Hydatid disease, the parasitic infestation caused by the cestode, echinococcus granulosus involves mainly the liver and the lungs though no organ is immune. Genito urinary involvement has been found mainly in the kidneys and rarely in other structures such as, bladder and epididymis. Isolated retrovesical location of the hydatid cyst is a very rare condition whose manifestations appears after a long course of the disease and are due to compression of bladder, causing the bladder out flow obstruction. Such rare case of bladder out flow obstruction is presented...

INTRODUCTION: Hydatid cyst represents a real public health problem in Tunisia. Retrovesical hydatid cyst is rare (6% to 7%). It is considered to be an "aberrant" or "ectopic" site defined by the development of the parasite in the subvesical and retrovesical fat. MATERIALS AND METHODS: From 1988 to 2001, 8 patients with retrovesical hydatid cyst were hospitalised and operated in our Urology department at Sahloul Hospital in Sousse, Tunisia. The mean age of our patients was 41 years (range: 8 to 75 years)...

A 13-y-old male patient presented with acute urinary retention and bilateral lumbar pain. The routine laboratory tests were normal. Casoni's skin test and indirect haemagglutination assay (1/160) were positive. Evidence of hydatid disease was found during surgery. Histopathological examination confirmed hydatid disease in the surgical specimens.

This study reviews urinary hydatid disease in seven males and three females (mean age, 32.1 +/- 17.7 years; range, 7-67 years). Cysts were located in the kidney in six cases (one also involved the liver), the paravesical and retrovesical region in two cases (one coexisted with a bladder tumour), the adrenal gland (one case) and in the right parapelvic region (one case). Investigations included urinalysis, eosinophil count, Casoni skin test, indirect haemagglutination test (IHA), abdominal ultrasonography, intravenous urography and computed tomography (CT)...

The aim of this study is to review 9 cases with urinary tract hydatid disease in terms of symptoms, findings, laboratory tests, radiological findings and treatment modalities. There were 7 males and 2 females with a mean age of 33.6 years (range from 7 to 67 years). In 6 patients hydatid cyst was located in the kidney (1 involved the liver), in 2 the cysts were in the paravesical and retrovesical region (1 coexisted bladder tumor) and 1 the cyst was located adrenal gland. The investigations included urinalysis, eosinophil count, Casoni skin test, indirect haemagglutination test (IHA), transabdominal ultrasonography (TAUS), intravenous urography (IVU) and computed tomography (CT)...

All organs in the human body may be affected by hydatid disease. Urinary tract involvement in hydatid disease is not common, corresponding to only 2-4% of cases. The kidneys are the most commonly affected organs in the urinary tract. We report a case of hydatid cyst of the urinary bladder.

OBJECTIVES: We report our experience with 27 cases of retrovesical hydatid cysts (RVHC) and discuss the pathogenesis, diagnosis and treatment of this hydatid location. MATERIALS AND 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...

The present study reported two cases of hydatid cysts localized in Douglas space and that broke in the bladder. The clinical course was characterized by urinary symptoms and by presence the cysts in urine. Abdominopelvic ultrasonography is essential for diagnosis and identification of other sites. When diagnosis is unclear, then CT scan plays a role. Therapy included cystectomy and pericystic resection in one case and intravescical injection of H2O2 in the second case. The course was favorable in both cases...

Hydatid cysts of the sacrum are rare entities, characterized by chronicity without any clinical manifestation and are usually misdiagnosed in the early stage resulting in significant loss of bone and destruction of surrounding tissue. One should keep this possibility in mind in cases of early sphincteric involvement with minimal sensorimotor deficit in the lower limbs and bone destruction on radiography.

OBJECTIVE: To determine the clinical, radiological and surgical features of retrovesical, retroperitoneal hydatid cyst and to discuss the aetiology and pathogenesis. MATERIAL AND METHODS: Nine cases of hydatid cyst operated in the urology department of Charles Nicolle hospital in Tunis between 1982 and 1998 were reviewed: five retroperitoneal sites and 4 retrovesical sites. RESULTS: Retrovesical and retroperitoneal sites represent about 10% of all operations for hydatid cyst in our department...

A 70-year-old man presented with a large suprapubic mass. Ultrasonography revealed that the mass was cystic and displaced the bladder anteriorly and superiorly. Computed tomography suggested that the mass could be an echinococcal cyst. Computed tomography also showed that the patient had bilateral hydroureteronephrosis. Echinoccocal haemagglutination was positive at 1:320 dilution. The patient underwent surgical exploration during which the cyst was found to be located in the retrovesical region. The cyst was completely excised and the pathologic examination confirmed the diagnosis...
