Clean intermittent self-catheterisation in 172 adults.

We report the results of clean intermittent self-catheterisation (CISC) in 172 adults (68 male, 104 female). Seven patients were unable or unwilling to master the technique and 145 still remain on CISC, representing a total experience of 6981 patient-months. Ten patients required readmission: 5 for retraining and 5 for complications (average hospital stay 2.4 days); 123/163 patients catheterised themselves every 3 to 4 h and 92 were continent on CISC; of the 107 patients incontinent prior to starting CISC, 101 were improved; 70 patients had no infections whilst on CISC, the mean infection rate being 1 per 14 patient-months; 29% of patients experienced persistent urethral bleeding; 156/163 patients were satisfied or very satisfied with CISC and 140 found the technique easy or very easy; 76 patients had never visited their GP for a urinary problem whilst using CISC and the mean rate was 1 visit per 8 patient-months. CISC is an easily learnt technique that is safe and acceptable to patients, and one which places few extra burdens on hospital or community resources.

Measurement of voiding pressures on ambulatory monitoring: comparison with conventional cystometry.

A series of 20 patients underwent conventional medium fill cystometry (CMG) and ambulatory monitoring during natural bladder filling (AM). The measurement of voiding pressures by the 2 techniques was compared. The maximum subtracted detrusor contraction pressure recorded during CMG (50 +/- 30 cm H2O) was significantly less than that recorded during AM (86 +/- 35 cm H2O). Voiding pressures during natural filling are greater than those observed during conventional urodynamic studies: this finding may have important implications in the definition of bladder outflow obstruction.

Outcome of elective prostatectomy.

OBJECTIVES: To determine the symptomatic and urodynamic outcome of elective prostatectomy and to establish whether the outcome is influenced or can be predicted by preoperative urodynamic measurements. DESIGN: Prospective non-randomised study with follow up at a mean of 11 months after operation. Most men were assessed jointly by a urologist and a general practitioner. SETTING: Department of urology in a teaching hospital serving a large district population. PATIENTS: 253 Men listed for elective prostatectomy because of symptoms and low urinary flow rates (less than 15 ml/s) and excluding those already on a waiting list or with acute urinary retention, clinically apparent prostatic cancer, and neurological or cerebrovascular disease; 217 (86%) were followed up. INTERVENTION: Elective prostatectomy. MAIN OUTCOME MEASURE: Classification on the basis of relief of symptoms assessed by patients and urologist and general practitioner and of symptom scores obtained by questionnaire. RESULTS: Of the 217 men followed up, 171 (79%) had a satisfactory subjective review and 155 (72%) had a satisfactory review and also low symptom scores. An unsatisfactory outcome was associated with preoperative symptoms of urge incontinence, small prostatic size and resected weight, low voiding pressures, and low urethral resistance. Preoperative maximum urinary flow rates did not predict outcome. Men with poor outcome could be classified into two groups: those with irritative symptoms who were more likely before operation to have had urge incontinence and detrusor instability and men with symptoms of poor urinary flow who were more likely before operation to have had a small prostate, low voiding pressures, and low urethral resistance. In patients in the second group flow rates or voiding pressures improved little after operation. Men with stable detrusors and either low urethral resistance or low voiding pressures were less likely to do well after prostatectomy, but despite these associations preoperative urodynamic measurements were unable to predict outcome accurately. CONCLUSIONS: Prostatectomy was satisfactory in relieving symptoms and improving urodynamic measurements in most men, but even in those with classic symptoms and low urinary flow rates a substantial minority experienced little improvement afterwards and urodynamic measurements did not accurately predict outcome in individual patients.

Ambulatory monitoring of bladder pressures in patients with low compliance as a result of neurogenic bladder dysfunction.

A group of 28 patients with neurogenic bladder dysfunction and low bladder compliance was studied using medium fill cystometry (CMG) and ambulatory monitoring (AM) during natural bladder filling. The aims of the study were to compare the 2 techniques and to determine if ambulatory monitoring might be useful in predicting upper tract dilatation. AM demonstrated significantly lower end filling pressures compared with CMG. Phasic detrusor contractions were found more commonly during AM and the frequency of phasic detrusor contractions during AM was associated significantly with poor compliance identified during CMG. Patients with upper tract dilatation had significantly greater residual urine volumes, higher pressure rises during CMG and higher frequencies of phasic detrusor contractions compared with those patients with normal upper tracts. The high pressures seen at the end of a medium fill CMG were not found during AM and therefore are unlikely to be the underlying explanation of upper tract dilatation in such patients.

A three year comparison of acute respiratory disease, shrink and weight gain in preconditioned and non-preconditioned Illinois beef calves sold at the same auction and mixed in a feedlot.

During 1969 to 1971, 78 preconditioned (PC) and 79 non-preconditioned (NPC) beef calves were purchased at the same auction and mixed in a feedlot. Preconditioned calves were weaned 30 days before the sale, used to drinking from a tank, and vaccinated against blackleg, malignant edema, infectious bovine rhinotracheitis (IBR), parainfluenza-3 (PI3) and bovine virus diarrhea (BVD) in 1970 and 1971, and Pasteurella hemolytica and multocida in 1971. All vaccinations were completed two to three weeks before the sale. PC calves were given thiabenzadole. PC calves had significantly less shrink after shipment and in 1971 significantly more rapid daily gain during the first weeks of the feeding period. In 1969 more PC calves were treated for acute respiratory disease than NPC calves during an outbreak of PI3 and BVD infection. In 1970 and 1971 fewer PC than NPC calves were treated for acute respiratory tract disease during outbreaks of PI3 infection. The differences in clinical respiratory disease were significant in 1971. Inclusion of two doses of P. hemolytica and P. multocida bacterin before the sale in 1971 and use of an intranasal PI3 vaccine was considered to improve the PC program. Fecal egg counts for gastrointestinal nematodes were much lower in PC calves treated with thiabenzadole than untreated NPC calves.
