Retention of urinary catheters is an increasing complication in our pr
actice. We have reported 18 patients seen over a 6-month period during
which 528 catheterizations were done, representing an incidence of 3.
4%. Various forms of management were offered and blind percutaneous su
prapubic puncture (BPSP) was found to be simple and effective. One out
of 13 patients, however, undergoing BPSP developed transient haematur
ia. The high incidence of malfunctioning catheter balloon mechanisms m
ay be due to poor quality equipment or lack of appropriate storage fac
ilities.
