hydatid cyst of urinary bladder

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.

UNLABELLED: Hydatid disease is an endemic zoonosis in regions with temperate climates where pastoral farming is common. Retrovesical localization is rare. Given the rarity of this entity, the lack of personal clinical experience, and the difficulty with detecting early symptoms, the diagnosis remains elusive for years. METHODS: This is a 30-year retrospective, descriptive and analytic study of seven patients who were hospitalized and operated on in the Department of Urology during 30 years (1990-2019)...

Hydatid cyst of Echinococcus granulosus usually develops in liver and lungs of the affected individual and is considered a common health problem in endemic regions. Although, the cyst can be found in less common locations, such as brain, heart, and bones, the urinary bladder is extremely rare that may mimic malignancy radiologically and creates a diagnostic dilemma for clinicians and radiologists. Here we present a unique case of hydatid cyst in the urinary bladder with associated eosinophilic cystitis.

Pelvis is a rare location for occurrence of hydatid cyst with only a few cases reported in the literature. All the previous reports of pelvic hydatid cysts were managed with either surgical exploration and excision or laparoscopic intervention. In this case report, we describe the successful treatment of a large pelvic hydatid cyst located in the retrovesical space using the percutaneous aspiration, injection, and respiration (PAIR) technique. To the best of our knowledge, this is the first successful demonstration of the PAIR technique in the treatment of retrovesical pelvic hydatid cyst...

Renal hydatid is an uncommon finding, reported in less than 5% patients with hydatid infection. Hydatid involvement of ureter and urinary bladder is an even rarer entity. Renal hydatid is typically unilateral, solitary and arise from cortex. It is essential to be aware of the imaging features of the hydatid cyst for proper diagnosis. Knowledge of the imaging features of various stages is essential since treatment decision is based on cyst stage. Hydatid cyst can mimic several entities both benign and malignant...

Abdominal hydatidosis resulting in an internal hydatid bladder fistula postoperatively is quite rare and might have serious consequences without timely treatment. A 74-year-old Tibetan woman presented with abdominal distension and was diagnosed with hydatid disease. Cyst contents were removed, and the pericyst was partially resected without contraindication. Furthermore, no internal urinary fistula was found before or during the operation, and the presence of an internal fistula was indicated by methylene blue retrograde injection via urinary catheter after the operation...

Solitary primary pelvic intraperitoneal hydatid cysts are rare. We report the case of a 22-year-old women who presented with a dull ache in her lower abdomen for 2 years and increased urinary frequency over 3 months. Ultrasonography and CT indicated a solitary primary peritoneal pelvic hydatid cyst. Hydatid serology was positive. Perioperative albendazole was prescribed and laparoscopic cystectomy planned. Intraoperatively, dense adhesions to the omentum, urinary bladder, and left fallopian tube were taken down laparoscopically...

Parasites and bacteria have co-evolved with humankind, and they interact all the time in a myriad of ways. For example, some bacterial infections result from parasite-dwelling bacteria as in the case of Salmonella infection during schistosomiasis. Other bacteria synergize with parasites in the evolution of human disease as in the case of the interplay between Wolbachia endosymbiont bacteria and filarial nematodes as well as the interaction between Gram-negative bacteria and Schistosoma haematobium in the pathogenesis of urinary bladder cancer...

Hydatidosis is an important zoonotic parasite disease in several herbivorous mammals. Human cystic echinococcosis (CE) caused by infection with larval stage of Echinococcus granulosus has been frequently reported from different organs. Here, we report the first case of a urinary echinococcosis in Iran with a pain in the lower left abdominal quadrant and severe frequent urination (pollakiuria). We detected a cyst 120 × 15 mm dimensions with heterogeneous mass contain fluid in the back of the urinary bladder neck between the umbilical region and external urethral sphincter...

Introduction: Hydatid cysts most commonly present in the liver and the lungs; however, they can appear more rarely in other locations, such as the mesentery, with a rather unclear mechanism of manifestation. Herein, we present a case of simultaneous presence of hydatid cysts in the liver and the mesentery of a young man. Case report: A 39-year-old man was referred to our Department for further investigation of intermittent abdominal pain, especially in the right upper quadrant, and abdominal distension...

Causes of urinary retention in old men include benign prostatic hyperplasia, prostatitis, prostate cancer, Scarring of the urethra or bladder neck as a result of injury or surgery, use of certain medicines particularly NSAIDs and opioid analgesics, constipation and neurogenic bladder. When the above common causes are not quite obvious by clinical examination and relevant investigations, then it is necessary to think of other rare diseases. It is with the above in our mind that a case of bladder outflow obstruction due to a large primary retrovesical hydatid cyst is herein reported in a 58-year-old man...

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)...

Cystic hydatidosis (CH) is a worldwide distributed parasitic zoonosis. It is considered one of the 17 neglected parasitic tropical diseases, among cysticercosis and soil transmitted helminthiases. CH is caused by the larval stage of Echinococcus granulosus, a tapeworm that usually infects dogs and other carnivorous animals as definitive hosts and herbivorous animals and rarely humans as intermediate hosts. Main primary localizations are the liver and the lung. In less than 3% they can primarily be present in the spleen...

Retrovesical cysts are extremely rare. For differential diagnosis radiologic findings and serologic tests can be used. In this article, we aimed to report our approach to diagnose and to treat a primary huge hydatid cyst in retrovesical space, between sigmoid colon and bladder. A 34-year old patient presented to our hospital with lower urinary tract symptoms (LUTS). Abdominal ultrasound reported a 14x8 cm cystic lesion adjacent to the posterior wall of the bladder. Computerized tomography revealed a 14 x 8 cm cystic mass adjacent to bladder posteriorly and prostate and seminal vesicle anteriorly in the retrovesical space...

OBJECTIVE: To present the therapeutic management of intractable hematuria secondary to systemic amyloidosis with bladder involvement. METHODS: We describe the clinical case, the medical management, the endo-urological technique used, and the results supported by relevant published literature. RESULTS: A 50-year-old woman with a 20-year history of rheumatoid arthritis in chronic treatment with corticosteroids and non-steroidal anti-inflammatory drugs in addition to chronic renal insufficiency not requiring hemodialysis...

Some of the metacestodes are not only zoonotic but are also responsible for severe tissue damage, reduction in milk and meat production, and considerable economic loss due to condemnation of the infected organs of the herbivorous animals. The aim of the present study was to determine the prevalence of Cysticercus ovis, Cysticercus tenuicollis, hydatid cyst and Coenurus gaigeri in sheep and goats and Cysticercus bovis, Cysticereus tenuicollis and hydatid cyst in cattle. A total of 1050 sheep, 950 goats and 500 cattle slaughtered at Shiraz Slaughterhouse were carefully examined for these metacestodes...

We present a technique of transurethral transvesical endoscopic management of an intraperitoneal retrovesical hydatid cyst. Cystoscopy is performed using a 20.8F nephroscope. The cyst is punctured using an 18-gauge, 36-cm needle through the nephroscope operating channel. Saline (20%) is used as scolicidal agent. After balloon tract dilation, the nephroscope is introduced into the cyst, and the hydatid material is evacuated.

About 75% of all hydatid cysts are located in the liver and they are singular. Extrahepatic hydatid cysts are rare pre- and intra-operative findings. The majority of such locations are consecutive from a hepatic primary. We present the clinical case of a 28-years woman, clinically diagnosed with a pelvic tumor. Ultrasonography and CT-scan showed two large tumors: a 17/10 cm left liver cyst, that contained free floating hyperechogenic hydatid sand and a 12/11 cm pelvic cyst, that displaced the urinary bladder, the uterus, the sigmoid colon and the rectum...

Echinococcosis or hydatid disease which is caused by Echinococcus group of cestodes is very rare in pregnancy. While liver and lungs are commonly involved, other sites can be rarely affected. The management of hydatid disease in pregnancy is challenging in view of varied presentation and manifestation. We report a case of hydatid cyst arising from the bladder associated with pregnancy and presenting with abdominal pain. The cyst was surgically removed and the bladder wash was given with povidone-iodine. The postoperative recovery was uneventful with ongoing pregnancy...
