[Non-improvement after different procedures of prostatectomy].
OBJECTIVE
To analyze the causes of non-improvement after different procedures of prostatectomy.


METHODS
Using the urodynamics and other techniques, we examined 84 non-improved patients who had undergone different procedures of prostatectomy.


RESULTS
In the TURP group, the main causes of non-improvement included bladder outlet obstruction (84.9%), weak contractility of the detrusor (30.4%), and detrusor instability (DI) (18.2%). In the open group, however, the main causes of non-improvement included detrusor weak contractility (52.9%), DI (35.2%), and bladder outlet obstruction (33.3%). There was significant difference between the two groups according to the Pearson Chi-square test (P = 0.000). The re-obstruction rate in the TURP group was much higher than that in the open group, suggesting that the level of the TURP should be improved.


CONCLUSIONS
Different operative procedures yield different non-improvement after prostatectomy gradually. When BPH patients are diagnosed with detrusor weak contractility and DI, prostatectomy should be carefully considered.
