TI  - Radionuclide assessment of bladder-emptying function in normal male population 
      and in patients before and after prostatectomy.
PG  - 353-7
AB  - Radionuclide assessment of the bladder-emptying function was evaluated in 82 
      normal individuals and in 16 patients before and after prostatectomy. The 
      parameters evaluated were: average flow rate (AFR), peak flow rate (PFR), 
      corrected peak flow rate (CPFR = PFR/[bladder volume] 0.5), ejection fraction 
      (EF) of the bladder, and post-voiding residual urine (RU) volume. A good 
      interobserver reproducibility was found in 19 measurements. Urinary flow rates, 
      EF, and RU showed a highly significant statistical difference between normal 
      individuals and patients before surgery: AFR, 9.2 +/- 5.1 vs. 2.9 +/- 1.5 mL/sec; 
      PFR, 19.5 +/- 9.2 vs 7.4 +/- 3.2 mL/sec; CPFR, 1.17 +/- 0.34 vs 0.54 +/- 0.22; 
      EF, 95.6 +/- 4.6 vs 68.2 +/- 23.2 percent; and RU, 11.8 +/- 15.8 vs 93.4 +/- 115 
      mL; respectively. After prostatectomy the urinary flow rates showed a highly 
      significant improvement and did not differ from the normal individuals: AFR, 7.9 
      +/- 2.7 mL/sec; PFR, 19.0 +/- 6.4 mL/sec; and CPFR, 1.32 +/- 0.57. The EF after 
      surgery (91.7 +/- 10.9%) was lower than in normal individuals, but showed a 
      significant improvement compared with EF before surgery. The RU after surgery 
      (27.4 +/- 48.0 mL) although lower than before surgery did not differ 
      significantly and was greater than in the normal individuals. No relationship 
      between age and flow was found in this study. Both average and peak flow rates 
      were related to the bladder volume. This method involves a single, noninvasive 
      procedure which enables determination of bladder-emptying function.
