Abstract

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 patients underwent various surgical procedures and were followed-up for an average of 3 years (range: 1 month to 5 years) period in terms of complications and recurrence rates. The most common symptom was lumbar or abdominal pain. Eosinophilia was seen in 4 patients (44.4%), IHA positivity in 3 patients (33.3%) and Casoni skin test were positive in 3 patients (33.3%). The most diagnostic method of radiological investigations was abdominal pelvic CT (100%). After surgical treatment, in mean a 3 year (range: 1 month to 5 years) follow-up period, no complication and recurrence were seen. Hydatid disease of the urinary tract is relatively uncommon and is likely to cause considerable diagnostic difficulties for clinicians and radiologists: therefore, it should be born in mind in the differential diagnosis of space-occupying lesions of the urinary tract.

Acute urinary retention due to cystic echinococcosis: A case report

“…There are no specific clinical symptoms and signs that will enable accurate diagnosis of urinary tract CE. 10 The symptoms of CE are generally the same as those of other space-occupying lesions, except for hydaturia caused by rupture of the cyst into the collecting system of the urinary tract. The symptoms of our case were non-specific, including lumbar or abdominal pain, malaise, nausea and vomiting, as well as irritative and obstructive lower urinary tract symptoms.…”

Diagnosis and Surgical Treatment of Renal Hydatid Disease: a Retrospective Analysis of 30 Cases

“…When the kidney is damaged, nephrectomyis necessary. Medical management of renal hydatidosisis far from being are realistic alternative to surgery and should be considered as adjuvant therapy [40]–[42].Chemotherapy,as an adjuvant therapy,with or without puncture aspiration-injection-re-aspiration (PAIR) is suitable for inoperable renal hydatid disease [43]–[44], however,none of patients in this study were receive methodology. Surgery may cure the patient completely but does not totally prevent recurrence.…”

Clinical and Demographic Characteristics of Patients with Urinary Tract Hydatid Disease

“…Urinary tract CE can be difficult to diagnose due to the slow growth of cysts, the presence of non-specific and subtle clinical manifestations, and the rarity of daughter vesicles in the urine, the defining sign of this disease [4], [22], [23]. In this study of 19 patients with renal or urinary tract CE, 16 patients exhibited lower back pain and upper abdominal pain, 7 patients experienced percussion tenderness over the kidney region, but only 1 patient had daughter vesicles in the urine.…”

“…Conservative surgery tends to have greater kidney preserving capabilities, and is appropriate for ∼75% of renal CE cases, but radical surgery is necessary for ∼25% of cases [13], [14], [15], [16], [17]. The conservative surgery, cystectomy with simple drainage [9], [21], [22], [23] was performed on 15 of 19 patients in this study. Postoperative urine leakage occurred in 6 of these cases, but no fistula was found in 5 cases before or after surgery.…”
