“…Recently, an in vivo study on rats showed how large bladder diverticula can alter bladder storage and emptying and can lead to dysfunctional voiding (14). Furthermore, bladder diverticula with a diameter > 5 cm seems to increase the risk of acute urinary retention in benign prostatic hyperplasia (BPH) patients (15).…”

Objective: To present the results of the largest series of patients with bladder diverticula > 4 cm managed with an endoscopic approach and give tips about the execution of the procedure. Materials and methods: Data of male patients undergone the endoscopic approach for an acquired bladder diverticula > 4 cm from December 2004 to August 2018 were prospectively collected and retrospectively analyzed. The description of the monopolar and bipolar techniques are provided. The success of the procedure was defined as the reduction of the diverticula for more of the 80% of its initial diameter documented at the 3- months follow-up imaging. Continuous variables with nonparametric distribution were compared using the Mann-Whitney test, while frequencies of categorical variables were compared between groups by Fisher’s exact test with significance level set at 0.05. Results: Thirty-nine patients with a mean (+/- SD) age at surgery of 69.4 ± 8.8 years were enrolled, for an equal number of diverticula managed. The mean diverticular size was 75.1 ± 24.5 millimeters. The mean operative time was 65 ± 21.9 minutes including the prostate surgery. Twelve patients (30.8%) were managed with bipolar energy, the others with monopolar. The success of the procedure was achieved in 30 patients (76.9% - 7 bipolar and 23 monopolar - p = 0.66). Conclusions: The endoscopic approach might be considered as a useful option for patients with a large bladder diverticulum who are at risk for major or laparoscopic procedure.

“…Celebi et al . [ 5 ] evaluated the effect of BD on bladder function using an animal model with rabbits testing the urodynamic profile and functional results of animals that were inducted with BD. They found that BD effectively causes dysfunctional micturition with involuntary contractions, decreased storage capacity, and affects bladder compliance.…”

A bladder diverticulum (BD) is a herniation of the bladder urothelium through the muscular bladder wall. As a result, BD presents as a thin walled bag, urine filled connected to bladder lumen through a neck or ostium. The clinical problem with bladder diverticula is their poorly empty during micturition which results in multiple lower urinary tract symptoms as well as recurrent urinary tract infections. Bladder diverticula can be grossly classified in two groups as follows: congenital or acquired with different age presentation and etiological factors in each one. Vast majority of BD occur in adults especially in men. Acquired BD, are commonly diagnosed in the setting of neurogenic dysfunction or bladder outlet obstruction, they use to be multiple, associated with trabeculated bladder and prostatic enlargement.

“…Although acquired bladder diverticulum is a disease that has been known and treated for a long time, there are not many urodynamic studies in patients with bladder diverticulum in the literature. Celebi et al [1] showed that large or multiple bladder diverticulum can change the bladder filling and emptying function, reduce the capacity of the bladder, and reduce its elasticity in the rabbit model. They suggested that large or multiple bladder diverticulum may cause voiding dysfunction by leading to involuntary bladder contractions.…”

“…They suggested that large or multiple bladder diverticulum may cause voiding dysfunction by leading to involuntary bladder contractions. [1] The result of the urodynamic analysis of 91 male patients by Adot Zurbano et al [2] showed that detrusor contraction time was the only contractility parameter that was significantly affected in the bladder diverticulum, and there was a significant relationship with the use of abdominal pressure during emptying the bladder. They concluded that diverticulectomy provided improvement in bladder contractility.…”

“…In a urodynamic study of the patients with acquired bladder diverticulum, decreased bladder capacity, detrusor overactivity (DOA), and decreased compliance in the storage phase, detrusor underactivity (DUA) and outlet obstruction were found to be more common in the voiding phase. [1] When viewed from this aspect, preoperative urodynamic analysis can also be used to predict postoperative outcomes.…”

Objective: Although bladder diverticulum is a disease that has been known and treated for a long time, there are not enough urodynamic studies about patients with bladder diverticulum in the literature. In this study, it was aimed to describe the urodynamic findings in the storage and voiding phases of the lower urinary tract in patients.Methods: Patients who applied to the urology clinic with lower urinary tract symptoms between February 2010 and August 2020 and who were found to have bladder diverticulum were evaluated retrospectively. Fifty patients who met the study inclusion criteria were considered. The medical histories, physical examinations, laboratory tests, imaging results, urodynamic study results, and the surgery reports of all the patients were reviewed retrospectively. Results:Of the patients included in the study, 18% were women and 82% were men. Fifty-four percent of the patients applied to the polyclinic with voiding symptoms. Four percent of the patients with bladder diverticulum were asymptomatic. It was determined that 60% of the male patients with a history of urological operation were treated for infravesical obstruction. Of the total patients, 22% were followed up without any surgical treatment. A urodynamic study was performed in 50% of the patients. The most common urodynamic finding was detrusor overactivity, followed by obstructed outflow function. Conclusion:As most of the patients with bladder diverticulum are asymptomatic, diverticulectomy is not indicated in every patient. First of all, patients should be investigated for the pathology causing diverticulum formation, and then the follow-up or the treatment options should be considered. Therefore, it could be argued that all patients with bladder diverticulum should be evaluated urodynamically. Further research is needed to explore this issue.
