In cases of missed preoperative diagnosis of prostatic cancer and benign hyperplasia, the recovery of unassisted urination in patients who previously have undergone transvesicular adenomectomy is often accompanied by traumatic removal of the tissues. This leads to severe anatomical changes of the cervicourethral segment in the form of postoperative strictures with occasional complete obliteration of the posterior urethra. If endoscopic correction of the posterior urethra fails to produce a persistent therapeutic effect, it is valid to perform urethral invagination into the bladder cervix according to Solovov for restoration of the bladder reservoir function, prevention of its fusion and progression of chronic interstitial cystitis. The case demonstrates successful recovery of the patency of the vesicourethral segment and capacity of the bladder in complete obliteration of the posterior urethra and small urinary bladder.
