Abstract

Introduction: Bladder diverticula are urothelium herniations that pass through the bladder muscle. The perivesical fat is in direct contact with the urotheliumdiverticularis. As a result, tumours developing from the urotheliumdiverticularis have a distinct evolutionary history from classical bladder tumours and are rarely linked with a bad prognosis. Objective: To assess the management of intraverticular bladder tumours. Material and Methods: This is a retrospective study on intradiverticular bladder tumours from January 2012 to December 2017 (i.e. 6 years) at the urology department of Casablanca’s UH Ibn Rochd. The study included all patients with an intradiverticular bladder tumour and a complete file. Results: The mean age was 63.75 years (with extremes of 44 and 88 years) and the The delay between the onset of symptoms and the consultation was 12.83 months. In all cases, hematuria was the most common symptom for consultation. Smoking (66.66 percent) and recurrent urethritis were identified as two risk factors (16.67 percent). In 50% of the patients, ultrasound revealed a diverticulum with tumour material, and CT scans revealed a tumorous diverticulum in 6 cases. Urothelial carcinoma was the most frequent histological type (83.33 percent), followed by squamous cell carcinoma (16.67 percent). After surgery, the pT3 grade was the most prevalent. In three and nine cases, surgery was conservative and radical, respectively. After three years of follow-up, the majority of patients had a favourable outcome with no recurrence. Conclusion: Intraverticular bladder tumours differed from classical bladder tumours in that they had a higher frequency of T3a tumours and non-urothelial carcinomas, as well as a risk of underestimated extension and tumour multifocality. In the majority of cases, their prognosis is bleak.
