There are various treatment options for symptomatic bladder diverticulum, including robotic-assisted laparoscopic bladder diverticulectomy, open and endoscopic techniques. But, to date, the optimal surgical technique remains unclear.
To present the preliminary long-term follow-up results of a novel technique of dextranomer/hyaluronic acid copolymer (Deflux) plus autologous blood injection for correction of hutch diverticulum in patients with concomitant vesicoureteral reflux (VUR).
Patient and method
We retrospectively reviewed four patients who had hutch diverticulum with concomitant VUR and had undergone submucosal Deflux following autologous blood injection. Patients with neurogenic bladder, posterior urethral valve, or voiding dysfunction were excluded from the study. Success was defined as the resolution of the diverticulum, hydronephrosis, and hydroureter on ultrasonography at a 3-month follow-up and long-term symptom-free period.
Four patients with hutch diverticula were included. The median age at the time of surgery was 6.1 (range 3–8) years. Three of them had unilateral VUR, and one had bilateral VUR. During the procedure, a mean of 0.625 ml Deflux plus a mean of 1.25 ml autologous blood were injected submucosally for correction of VUR. Additionally, a mean of 1.62 ml Deflux plus a mean of 1.75 ml autologous blood were injected submucosally to occlude the diverticulum. The median follow-up was 4.6 (range 4–8) years. This method had excellent success in all patients in the current study with no postoperative complications such as febrile urinary tract infection, or diverticulum, hydroureter, or hydronephrosis in follow-up ultrasounds.
