Relationship between bladder trigone and bladder neck induced by traction of an indwelling balloon catheter with a spring balance and parameters of cystometrogram

Abstract

Sensation of the bladder trigone and bladder neck induced by traction of an indwelling balloon catheter with a spring balance and cystometry was evaluated in 393 males and 106 females. Male patients with an average age of 56. 9 ± 15. 9 (mean ± standard deviation) years old (range 17 to 88 years) were divided into 7 groups as follows: 19 patients without any micturitional disturbance, uregency and chronic prostatitis (11 patients), benign prostate hypertrophy (BPH) (131 patients), cervical or thoracic cord compression disorders (67 patients), lumbar vertebral disorders (114 patients), other peripheral nerve disorders associated with diabetes mellitus, post operative status of rectum cancer and others (27 patients) and brain diseases (24 patients). Female patients with an average age of 55. 2 ± 15. 5 years old (range 17 to 88 years) were divided into 6 groups as follows: 24 patients without any neurological problems, urgency (7 patients), cervical or thoracic cord compression disorders (11 patients), lumbar vertebral disorders (37 patients), other peripheral nerve disorders (18 patients) and brain diseases (9 patients). The observed sensation, first desire to void (FDV) and maximum cystometric capacity (MCC) were evaluated statistically in relation to clinical factors (e. g. disease group, generation and patterns of cystometrogram). The correlation between the sensation and FDV or MCC in these patients were assessed by linear regression analysis. Sensation of normal males was 334. 2 ± 159. 7 g on the average and correlated well with FDV (r=0. 88, y=375x -189. 4). Sensation of normal females was 373. 3 ± 199. 5 g on the average. However, there was no correlation (r=0. 35) between sensation and FDV in females. © 1992, THE JAPANESE UROLOGICAL ASSOCIATION. All rights reserved.
