Surgical treatment of a true diverticulum of the bladder in a patient with aplasia of the left kidney. Case report

A bladder diverticulum (BD) is a blindly terminating sac-like protrusion of the bladder wall with or without involvement of the muscular layer. BDs are categorized into true (congenital) and false (acquired), single and multiple. False diverticula are more common and develop in infravesical obstruction due to urethral stricture, prostate neoplasms, neurogenic disorders and other lower urinary tract diseases. Currently, there are no clear recommendations regarding the tactics of treatment of BD, so the choice of treatment method is based on the determination of the cause of BD, assessment of clinical manifestations and diagnostic results (localization, size, number, etc.), as well as the identification of concomitant anomalies and diseases of the upper urinary tract. The priority in the treatment of BD is surgical treatment. The article presents the observation of a patient with a developmental anomaly in the form of aplasia of the left kidney combined with a large congenital BD in the area of the missing mouth of the aplasic left ureter. The results of examination and treatment in the form of laparoscopic diverticulectomy are presented. A brief review of the literature on the problem of diverticulosis has been carried out.
