Comparison of voiding disturbances in patients with LUTS and BPH at home and by episodic checks at an outpatient clinic

To clarify the presence of voiding disturbances in patients with lower urinary tract symptoms (LUTS) and benign prostatic hyperplasia (BPH), measurements of the capacity at normal desire to void (CNDV), residual urine volume (RUV) and RUV rate at home and in a hospital were done. It has been found that (1) RUV and RUV rate in patients with BPH were markedly greater than that in the normal group and LUTS patients staying at home. Moreover, there was no difference in RUV and RUV rate between the normal group and the LUTS patients. (2) RUV and RUV rate in patients with LUTS and BPH decreased more markedly without changing CNDV when the patients stayed at home than when they underwent episodic checks in a hospital. In conclusion, frequent checks of LUTS and BPH in patients in their domestic environment can probably be utilized for management or determination of treatment.
