Objectives: To assess individually tailored ultrasound-assisted prompted voiding as a means of managing urinary incontinence in hospitalized elderly patients.

Methods: A total of 88 incontinent elderly individuals who were inpatients in general hospitals were included. Each individual's mean bladder volume before starting to void (voided urine volume plus residual urine volume) was regarded as the optimal bladder volume.

Aim: Chronic cystitis in diaper-dependent elderly patients can be a causative pathology for recurrent urinary tract infections (UTIs) in community hospitals.

Methods: We analyzed hospital infections to determine causative organisms from January 2007 to December 2009 in patients in a long-term care hospital. The reading causes of hospital infections were UTIs (30.

Objective: To evaluate usefulness and safety of an indwelling contemporary balloon catheter, we compared complication rates among five methods of urinary tract management.

Patients And Methods: History of febrile episode, bladder stones, pyuria and the miscellaneous urinary tract problems of 114 patients were retrospectively reviewed. The rates of complications were compared among five types of urinary tract management as clean intermittent catheterization dry (not incontinent) (CIC-dry: n = 33), clean intermittent catheterization with incontinence (CIC-wet: n = 16), clean intermittent catheterization with a contemporary balloon catheter indwelling at night (Contemporary catheter: n = 20), a suprapubic cystostomy catheter indwelling (Cystostomy: n = 22) and permanent urethral balloon catheter indwelling (Urethral catheter: n = 24).

The most frequent medical complication in patients with neurogenic bladder dysfunction is urinary tract infection (UTI). In the acute phase of neurogenic bladder, aseptic intermittent catheterization should be applied. After this phase, patients are subject to UTIs leading to febrile diseases.

Background: The ideal urological management for the patients with cervical spinal cord injury (CSCI) is to obtain catheter free urination and to prevent urinary tract complications. We have evaluated cases that had undergone transurethral anterior sphincterotomy from the view-point of the operative indications and the efficacy.

Methods: We carried out sphincterotomy 166 times on 133 male patients with CSCI in our Center.

The Injury Prevention Committee of the Japan Medical Society of Paraplegia (JMSoP) conducted a nationwide epidemiological survey on spinal cord injury (SCI) using postal questionnaires for 3 years periods from 1990 to 1992, and the annual incidence of the spinal cord injury was estimated as 40.2 per million. From this registry, we investigated SCI related to sports activities.

To eliminate severe leg spasms of 15 quadriplegics, 0.3 ml 10% phenol-glycerin was injected into the subarachnoid space at the T12/L1 interspace. The effectiveness for leg spasm was evaluated by the Penn spasticity and Ashworth rigidity scales.

During the last 10 years, 90 penile prostheses were implanted in 82 patients with spinal cord injury. Surgery was done 1 month to 25 years (average 4.8 years) after the injury.

A total of 68 ureteroneocystostomies performed between 1980 and 1992 in 63 patients with vesicoureteral reflux (UVR) secondary to neurogenic bladder were reviewed to elucidate factors of postoperative hydronephrosis. Urogram, cystogram, and urodynamics were analyzed, and the cases were classified into two types (areflexia, hyperreflexia) of detrusor muscle response. Occurrence or progression of hydronephrosis was demonstrated in 26 operations (complicated group).

From 1979 to 1989, 269 patients with spinal cord injury were managed by an aseptic intermittent catheterization program during the acute phase of their injuries at the Spinal Injuries Center. One hundred fifty one patients with incomplete cord lesion and 36 males with complete tetraplegia were managed by program I, which protects the shocked bladder from overdistention. In contrast, 82 patients with complete cord lesion excluding male tetraplegia were managed by program II, which allows overdistention of the bladder.

The urinary N-acetyl-beta-D-glucosaminidase (NAG) activities were determined in acute pyelonephritis patients with spinal cord injuries. The urinary NAG activity was significantly elevated in 23 of 31 cases (74%) compared with normal controls. Out of 7 acute pyelonephritis patients without spinal cord injuries, 4 patients (57%) showed significantly elevated urinary NAG activities.

During the last 5 years non-inflatable penile prostheses were implanted in 37 patients with spinal cord injury. Operation was done to provide adequate stability of the penis in order to hold an external urinary device, to help erectile impotence and to make self-catheterisation easier. A pair of Shirai-type silicone penile implants were inserted into the corpora cavernosa through a dorsal skin incision at the penile base.
