Abstract:
AIMS:To examine whether isolated bladder outlet obstruction in the absence of associated lower urinary tract abnormality results in hydronephrosis. Isolated obstruction causes a brief rise in bladder pressure that might not trigger hydronephrosis. METHODS:Data included adult men who underwent urodynamics for refractory non-neurogenic lower tract symptoms between 2011 and 2020. International Continence Society indices for obstruction (bladder outlet obstruction index [BOOI] ≥ 40) and underactivity (bladder contractility index [BCI] < 100) were calculated. Storage abnormality was defined as detrusor overactivity (DO) or poor compliance (<20 ml/cm H2 0). Isolated obstruction was defined as BOOI ≥ 40, BCI ≥ 100 and no storage abnormality. Nonparametric tests using R program (3.5.0) applied (p < .05 significant). Logistic regression analyses were performed to study the relationships of hydronephrosis with lower urinary tract function. RESULTS:A total 1596 men (range, 18-91 years; median, 51.0 years; Q3, 64.0 years; Q1, 34.0 years) were eligible. Hydronephrosis was noted in 274 (17.2%). A total of 45.4% were obstructed, 52.3% were underactive and 41.7% had storage abnormality. Storage abnormality (odds ratios [OR], 2.05; 95% confidence interval [CI]: 1.56, 2.69; p < .001) and bladder contractility (OR, 1.68; 95% CI, 1.25-2.26; p < .001) but not obstruction (OR, 1.07; 95% CI, 0.80-1.44; p = .634) was associated with hydronephrosis. Of eight possible combinations, men with BOO ≥ 40, BCI ≥ 100 and storage abnormality had highest probability of hydronephrosis (OR, 0.29; 95% CI, 0.24-0.33). Subanalysis showed that poor compliance (OR, 3.39; 95% CI, 2.49-4.60; p < .001) but not DO was associated with hydronephrosis. Younger age and higher postvoid residual urine were also associated with hydronephrosis. CONCLUSIONS:In adult men with refractory non-neurogenic lower urinary tract symptoms, isolated bladder outlet obstruction is not associated with hydronephrosis.
