Does urodynamics study help in evaluation and prognosis of treatment in benign prostatic hyperplasia with diabetes mellitus?

Abstract

Aims: The aim is to study the clinical significance of urodynamics study (UDS) in patients of benign prostatic hyperplasia (BPH), with and without diabetes mellitus (DM) and to predict the outcome of surgical depending on UDS findings. Materials and Methods: A total of 120 BPH patients were studied and divided into two groups, BPH with DM and without DM. Initial evaluation, diagnostic tests, and urodynamic examination were done in all patients, and results were statistically analyzed. Results: There was no significant difference of age and prostate volume in both groups (P > 0.05), but there was a significant increase in symptom score in patients of BPH associated with DM (P < 0.05). Bladder outlet obstruction (BOO) was found in majority of patients in our groups (96.66%) with good detrusor function. Out of 120 patients, 6 patients (2 patient in BPH group and 4 patients in BPH with DM group) had detrusor underactivity (DU). There was a significant difference in the International Prostate Symptom Score, quality of life, peak flow rate, and postvoid residual urine, pre- to post-operatively in each group (P < 0.05). Out of the 6 patients who had DU, 4 patients (1 patient in BPH group and 3 patients in BPH with DM group) showed improvement in their flow rate and symptom score. Conclusion: DM in cases of BPH patients is not the prominent factor in deciding surgical treatment. It is the severity of BOO which determines the treatment and its outcome. UDS is an invasive and costly test and does not appear to be mandatory in clinically significant BPH even if associated with DM.
