Management of the neuropathic bladder by suprapubic catheterisation.

Forty out-patients with neuropathic bladders managed by suprapubic catheterisation have been reviewed. Management included anticholinergic therapy and daily clamping of the catheter to maintain a compliant bladder of good capacity. Twenty-three females and 17 males (mean age 45 years) were studied. Failed intermittent catheterisation and the replacement of long-term urethral catheters were the main indications for suprapubic catheterisation. Catheter-related problems were common, with only 5 patients reporting none. Acceptance by patients was high (84%). No evidence could be found of accelerated renal deterioration in patients followed up for more than 2 years. A policy for the management of suprapubic catheters is recommended.

Chronic urinary retention postpartum.

Three cases of chronic urinary retention postpartum are reported. All patients were primigravidas. Unrecognized urinary retention following epidural anaesthesia in labour was the likely cause. Abdominal ultrasound may have a place in early recognition of this complication. The early use of a suprapubic catheter hastens bladder recovery.

Emergency serum and urine HCG analyses with the 'Tandem ICON' procedure.

A comparison between new urine and serum enzyme immunoassay techniques and existing serum radioimmunoassay techniques for the detection of HCG in the diagnosis of ectopic and early intrauterine pregnancy was undertaken. Urine HCG estimations by enzyme immunoassay were not found to be adequate for the exclusion of ectopic pregnancy due to a false negative rate of 12.5% (2 of 16 patients). Serum HCG estimations by enzyme immunoassay were found to compare favourably with radioimmunoassay techniques in the detection of HCG in both ectopic and early intrauterine pregnancy.
