Abstract:
Objective To evaluate the diagnostic value of uroflowmetry of specific bladder capacity in the detection of early diabetic cystopathy (DCP). Methods One hundred and nine patients with type 2 diabetes mellitus (DM) and 48 normal control subjects (control group) were completed the uroflowmetry in bladder capacity about 300 ml. The patients with DM were divided into DM course≥10 years group and DM course<10 years group, glycated hemoglobin (HbA1c)≥7%group and HbA1c<7%group according to the course and HbA1c. The volume leading to first bladder sensation, maximal flow rate (MFR) and average flow rate (AFR) of bladder capacity about 300 ml, and residual urine volume afteremptyingwere measured by uroflowmetry. Results Among the 109 patients with DM, 74 cases (DCP group) had residual urine, and the incidence of DCP was 67.89% (74/109). Thirty-five cases (no-DCP group) had no residual urine. In control group, 8 cases had residual urine. The MFR and AFR in DCP group and no-DCP group were significantly lower than those in control group: (14.44 ± 5.90) and (17.38 ± 5.93) ml/s vs. (23.73 ± 5.81) ml/s, (9.52 ± 4.97) and (10.38 ± 4.46) ml/s vs. (15.88 ± 4.95) ml/s, and the MFR and AFR in DCP group were significantly lower than those in no-DCP group;the residual urine volume in DCP group was significantly higher than that in no-DCP group and control group: 26 (15 - 40) ml vs. 0 and 0 (0 - 51) ml, and there were statistical differences (P<0.05). The MFR and AFR in DM course ≥ 10 years group (27 cases) and DM course < 10 years group (82 cases) were significantly lower than those in control group:(13.34 ± 5.48) and (16.07 ± 6.09) ml/s vs. (23.73 ± 5.81) ml/s, (8.62 ± 3.28) and (10.19 ± 4.96) ml/s vs. (15.88 ± 4.95) ml/s, and the residual urine volume was significantly higher than that in control group:18 (0-75) and 15 (0-30) ml vs. 0 (0-51) ml. The MFR in DM course ≥ 10 years group was significantly lower than that in DM course< 10 years group, and the residual urine volume was significantly higher than that in DM course < 10 years group. There were statistical differences (P<0.05). The MFR and AFR in HbA1c≥7%group (92 cases) and HbA1c<7% group (17 cases) were significantly lower than those in control group: (15.51 ± 5.98) and (15.53 ± 6.60) ml/s vs. (23.73 ± 5.81) ml/s, (9.92 ± 4.74) and (9.88 ± 4.72) ml/s vs. (15.88 ± 4.95) ml/s, and the residual urine volume was significantly higher than that in control group: 17 (0 - 35) and 0 (0 - 24) ml vs. 0 (0 - 51) ml. There were statistical differences (P<0.05). There were no statistical differences between HbA1c ≥ 7% group and HbA1c < 7% group (P>0.05). There were no statistical differences in volume leading to first bladder sensation (P>0.05). Conclusions MFR decrease detected with the technology of uroflowmetry specific bladder capacity may be widely used in screening early DCP.
