Abstract
ObjectiveTo determine the rate and the distribution of the structural defects in the urinary bladder complicating urethral stricture in men, and to compare the complications observed in the younger patients to those observed in the older patients.MethodsRetrospectively, case files of patients diagnosed of urethral stricture using retrograde urethrogram (RUG) and voiding cysto-urethrogram (VCUG) from February 2009 to August 2018 were analyzed. Stricture characteristics were outlined. In addition, complicating structural defects in the lower urinary tract proximal to the stricture site were documented. The complicating defects identified in the patients were segregated according to age for any observable associations. Logistic regression analysis was used to define the nature of the association of patient age, stricture site, number and length, with distribution of complicating structural defects. Analyses were done using SPSS® version 20.ResultsWithin the 10-year review period, 257 of 421 suspected cases of urethral stricture were confirmed. Patients are between 1 and 104 years of age (mean: 50.1 ± 19.1 years; median: 51.0 years IQR 35.0–65.0). Bulbar (34.2%); short segment (62.6%); partial (73.9%) strictures are prevalent. Forty-seven (18.3%) of 257 patients presented with 1 or more complications. Bladder diverticulum (8.6%) and urethra-cutaneous fistula (6.6%) are prevalent complications. The distribution of complications does not vary with age, or with stricture characteristics.ConclusionPresentation with complications is not uncommon. The distribution of these complications does not vary with age or with stricture characteristics.
Highlights
Urethral stricture (US) is a known cause of infravesical obstruction
This study will give an insight into the existence of age-related differences in the type and distribution of structural defects complicating prolonged infravesical obstruction from urethral stricture. This is a retrospective analysis of case files of patients diagnosed of urethral stricture using retrograde urethrogram and voiding cysto-urethrogram from February 2009 to August 2018
The structural changes in the lower urinary tract proximal to the stricture site detected through the contrast study were documented as well
Summary
Urethral stricture (US) is a known cause of infravesical obstruction. It develops as a consequence of healing with scaring of any significant inflammatory response of the urethra to any insult [1]. Such insult could be due to trauma, infection, allergy, caustics and so on [2]. Any part of the urethra from the prostatic urethra to the urethral meatus can be affected by this obstructing urethral disorder, but different parts predominantly manifest strictures from different aetiologic agents [3, 4]. Irrespective of the etiology, the mechanism of injury, Nnabugwu et al BMC Medical Imaging (2019) 19:84 the pathogenesis of the stricture and the anatomical site of the stricture, the resultant effect on urinary bladder emptying is the same: increased resistance to urine flow with recognizable consequences to the structure and function of the proximal urinary tract and the kidneys [6, 7]
