Communicating (Open) Renal Hydatid Cyst Managed Successfully with Renal Sparing Approach

Renal hydatid disease accounts for 2% of all cases of hydatid cysts. With the majority of isolated renal hydatid disease patients being asymptomatic, hydatid cysts grow slowly for several years. They may be associated with pressure symptoms or flank pain, depending on their size and location. Hydatiduria occurs in less than one-fifth of the patients. In the absence of hydatiduria, diagnosis is usually radiological. Surgery is the mainstay of treatment which is usually renal sparing surgery as most cysts are non-communicating. In cases of cyst communicating with the collecting system, nephrectomy remains the mainstay of treatment. We report a case of hydatiduria due to a communicating hydatid cyst diagnosed on CT urography, where a renal sparing approach was followed and the patient was managed with cystopericystectomy, closure of Pelvicalyceal System (PCS) and double J (DJ) stenting with an excellent result.
