Hydatid disease (HD) is an accidental human parasitic infestation by cestodes and is most commonly caused by Echinococcus granulosus. Liver happens to be the most common site of involvement, although involvement of other organ symptoms is not uncommon. Involvement of the retrovesical pouch by hydatidosis is generally secondary in nature with an incidence of 0.1%-0.5% only. Primary retrovesical hydatid cyst (RVHC) is extremely rare with only few cases in existing literature. RVHC can present with a wide gamut of symptoms ranging from asymptomatic to obstructive uropathy. A 38-year-old male presented to us with complaints of lower urinary tract symptoms (LUTS) and was found to have an isolated primary retrovesical hydatid cyst on evaluation. The RVHC had compressed the right ureter leading to a grossly hydronephrotic non-functional right kidney. The patient was started on albendazole therapy and underwent robot assisted right nephroureterectomy and partial pericystectomy for the RVHC. The postoperative period was uneventful with resolution of symptoms. This report highlights the various clinical presentations of RVHC as well as the minimal invasive management of this rare entity.
包虫病（HD）是一种由绦虫引起的人类意外寄生虫感染，最常见的病因是细粒棘球绦虫。肝脏是最常受累的部位，不过其他器官出现症状也并不罕见。膀胱后间隙受包虫病侵犯通常为继发性，发病率仅为0.1%-0.5%。原发性膀胱后包虫囊肿（RVHC）极为罕见，现有文献中仅有少数病例报道。RVHC可表现出从无症状到梗阻性尿路病等广泛的症状。一名38岁男性因下尿路症状（LUTS）前来就诊，经评估发现患有孤立性原发性膀胱后包虫囊肿。该RVHC压迫右侧输尿管，导致右侧肾脏严重肾积水且无功能。患者开始接受阿苯达唑治疗，并接受了机器人辅助下的右侧肾输尿管切除术及RVHC部分囊肿切除术。术后恢复顺利，症状得以缓解。本报告强调了RVHC的各种临床表现以及对这种罕见病症的微创治疗。
