Posterior urethral valves: Determinants of outcome in a developing country

Abstract

Significant cases of PUV present late with complications in our setting and have high morbidity and mortality. The poor outcome may be related to delayed diagnosis, poor renal function at presentation and poor renal support. Improving time to diagnosis and renal support may lead to better outcome.

Posterior urethral valve: a retrospective review of cases and challenges of management in a low-resource centre

“…The commonest symptoms observed was recurrent fever (75%) and straining at micturition (50%). This was similar to reports by Ikuerowo and Odetunde (2,7) but differs from most other studies where poor urinary stream was most common (1,9,11,13). Palpable bladder mass was the most common sign elicited among these patients (62.5%).…”

“…However, this was in contrast to 75.7% reported by Talabi et al from Ile-Ife, South-West Nigeria (12) and 68.3% by Uba et al from Jos, North-Central Nigeria (9). The median age at presentation was 26 months (2.2 years) with a range of one day to 11 years similar to the 2.5 years observed in the study by Okafor et al in Enugu (13).…”

“…Fortunately, ultrasonography is readily available in most developing countries. However, prenatal diagnosis of PUV still remains low in Nigeria (2,(12)(13)(14). In the present study, despite all the mothers having at least one antenatal ultrasound examination, only one (12.5%) had prenatal suspicion of PUV, and this was only made at 35 weeks gestation.…”

“…This rate was similar to the average annual number of three to eight PUV cases reported by Uba et al, at Jos, North-Central Nigeria (9) and seven by Jaja et al, at Port Harcourt, South-South Nigeria (5). Higher incidences of PUV in Nigeria have been reported, thus highlighting the magnitude of this problem in a developing country (2,13,16).…”

“…Прогресс и усовершенствование эндоскопических инструментов позволяют разрушать клапаны коагуляционными электродами или миниатюрными ножами. Однако первичная трансуретральная резекция КУ у новорожденных травматична, иногда очень трудно избежать ятрогенного повреждения уретры из-за размера и узости наружного отверстия мочеиспускательного канала [11,12]. После трансуретральной резекции КУ у детей сужение уретры развивалось в 9% случаев, а у новорожденных -в 50% [13,14].…”
