Endoscopic Management of Secondary Sclerosis of the Bladder Neck in Bouaké: Our Experience with 23 Cases

Background: Secondary sclerosis of the bladder neck is a rare but serious late complication that occurs after open or endoscopic prostatic adenomectomy. Objective: The aim of this study was to report the results of endoscopic management of secondary sclerosis of the bladder neck in a series of 23 cases. Patients and Methods: Cross-sectional study of 23 patients presenting with secondary sclerosis of the bladder neck following adenomectomy and treated by endoscopic resection of the bladder neck in a private facility in Bouaké (Ivory Coast) over the period from 1 January 2021 to 1 December 2022, i.e. 2 years. The mean age of the patients was 61, 7 years with extremes from 53 to 76 years. The diagnosis of secondary sclerosis of the cervix was based on clinical and radiological data (retrograde uretrocystography). The parameters studied were the reason for consultation, time to onset of signs after adenomectomy, clinical data, results of retrograde uretrocystography (RUC), results of urine cytobacteriological examination (UCT), complications, endoscopic procedure, duration of operation, duration of postoperative urinary drainage, duration of hospitalization, postoperative follow-up and operative morbidity and mortality. Results: 23 patients with secondary sclerosis of the bladder neck were treated by endoscopic neck resection. The mean age of the patients was 61.7 years (5 - 76 years). Dysuria was the most frequent reason for consultation, accounting for 73.9% (n = 17). Retrograde uretrocystography (RUC) was used to make the diagnosis in all patients. It found a steam jet image in 69.6% (n = 16) and tight stenosis of the bladder neck in 30.4% (n = 7). Secondary stenosis of the bladder neck was complicated by uretrohydronephrosis in 47.8% (n = 11). 73.9% of patients had a post-micturition residual of more than 150 ml. The urine cytobacteriological examination (UCE) found four urinary tract infections (17.4%) treated with antibiotics over 14 days, which sterilised the urine. The pathologies associated with cervical sclerosis were urethral stricture (13%) treated by endoscopic internal urethrotomy, and urinary lithiasis (8.7%) (n = 2). The mean duration of the operation was 53 minutes (43 - 60 min), the mean duration of postoperative urinary drainage was 3 days (2 - 6 days), and the mean duration of hospitalization was 5.4 days (3 - 6 days). Follow-up at 3 and 6 months using retrograde uretrocystography (RUC) showed good permeability of the neck and urethra with a post-void residual of
