[Urodynamic studies on benign prostatic hyperplasia combined with diabetes mellitus]

To evaluate urinary dynamics in the diagnosis, differential diagnosis, disease grades, complications, prognosis, and curative effect on benign prostatic hyperplasia (BPH) patients accompanied with diabetic mellitus (DM), and to investigate the clinical significance of urodynamic studies.

A total of 106 BPH patients with lower urinary tract symptoms were studied, aged 53-92(63.21+/-7.18) years. The mean duration of voiding symptoms was 3-12 years. These patients were divided into 2 groups: Group A consisted of 59 BPH patients while Group B consisted of 47 BPH patients combined with DM. Both groups were evaluated the international prostate symptom score(IPSS), urine flow rate, and residual urine volume. All patients underwent urodynamic examination. Correlation analysis was conducted to determine the correlation among the patients. The urodynamic results in different groups were compared.

The IPSS in Group A was higher than Group B, while the Qmax was lower than Group B. The unsatisfactory results of Group A was higher than Group B. There was significant difference between the 2 groups (P<0.05). There was no significant difference in residual urine volume between the 2 groups (P>0. 05). There was significant difference between the 2 groups in detrusor instability of the bladder, low compliance bladder, and damaged detrusor function (P<0.05).

The influence of DM on the function of the bladder in BPH patients is significant. Urodynamics can provide objective basis for the selection of therapeutic methods, and forecast the postoperative effect. It has an important reference value in BPH patients accompanied with DM.
