IntroductionProstate cancer (CaP) is the most commonly diagnosed cancer among Nigerian men but CaP screening is not a common practice. The true burden of the disease in Nigeria is not known. The study was aimed at studying the community burden of CaP in Lagos.MethodsDuring a community-based prostate cancer awareness program in 13 local government areas of Lagos, men aged >40 years had serum total PSA (tPSA) test and digital rectal examination (DRE). Those with abnormal DRE or tPSA >95th percentile of the cohort or both were selected for prostate biopsy (TRPB).Results4172 men were screened and complete data was available for 4110 (98.5%). The mean age was 60.8 years. DRE was abnormal in 410 men and was significantly correlated with the age of the patient and tPSA (p<0.001). The tPSA ranged from 0 to 438.3ng/ml with a median, mean and 95th percentile of 1.5, 2.5 and 10.0ng/ml respectively. 341 out of the 438(78%) men selected were subjected to TRBP. Forty-three men had histological diagnosis of CaP, giving an estimated prevalence rate of at least 1.046% or 1046 per 100,000 men of age ≥40. Only 11 (26%) had organ-confined disease while 17 (40%) had locally advanced disease and 15 (35%) men had metastatic disease. The majority of the men, 32 (74%) were reported to have Gleason's score of ≥7.ConclusionThe prevalence rate of CaP among men aged ≥40 years in Lagos is higher than previously reported in hospital-based study. Majority have advanced and high-grade disease.
BackgroundAcute urinary retention (AUR) is a common urological problem. We have observed a growing list of patients on indwelling bladder catheter awaiting surgery after AUR. This study was aimed at identifying the health, financial and quality of life (QoL) implications of prolonged use of indwelling catheter in these patientsMethodsWe review the side-effects, QoL and cost of changing an indwelling catheter among patients who were on the waiting list for definitive surgery after AUR. All the 62 patients who presented to weekly catheter clinic for change of the indwelling catheter were recruited over a 3 – week period into the study.ResultsThe mean age of the patients was 57.5 years and the mean catheter use time was 23 months. The aetiology of AUR was BPH in 40 (64%) and urethral trauma in 16 (28.4%) of the patients. The common side effects of prolonged catheterization included urethral/suprapubic pain, bleeding per urethram, loss of dignity, loss of job or being out of school, lack of sexual intercourse, pericatheter leakage of urine and recurrent urinary tract infection. The cost of change of the indwelling catheter to the patient each time ranged from 460.00 – 2500.00 Naira (averaged 789.67 Naira). The total annual cost for the change of indwelling catheter after AUR in our catheter clinic was estimated to be 7,350,000.00 Naira (58,800 US dollars) with 1,890,000.00 Naira (15,120 US dollars) being the cost borne by the patients per annum and the rest being government subsidy. Fifty-three (85.5%) patients described that they were unhappy. There was a significant correlation between QoL and the presence of pain (p = 0.015) and bleeding (p = 0.042) associated with the presence of an indwelling catheter.ConclusionThe need to have an indwelling catheter for a prolonged period after AUR is a painful experience and associated with several side-effects. This has a significant negative effect on the patients' QoL and constitutes a significant financial burden to the patients and the government. We suggest that measures should be put in place to reduce the waiting time for surgery and therefore the catheterization time among the patients with AUR.
Posterior urethral valve (PUV) obstruction is the most common cause of bladder outlet obstruction in boys. Currently, the diagnosis of PUV is commonly made prenatally. In our environment, however, prenatal diagnosis is rare and the diagnosis is usually made postnatally from the clinical and radiological features. This study therefore examines the clinical and radiological spectrum of boys with PUV in our environment. We examined the clinical presentations, ultrasonographic and the micturating cystourethrographic (MCUG) features of boys with PUV in our institution over a 22-month period from June 2006. There were 28 patients with PUV over this period. The age at presentation ranged from 11 days to 11 years (mean age = 2.7 years). Although prenatal ultrasound scan was done in 23 (82.1%) patients, no prenatal diagnosis was made in any of the patients. The diagnosis was made after infancy in 16 (57.1%) patients. Recurrent urinary tract infection (UTI) was the most common mode of presentation occurring in 14 (50.0%) patients with 7 (50.0%) of the patients with UTI presenting with septicaemia. Voiding dysfunctions, which occurred in all the patients, were the primary mode of presentation in 12 (42.9%) patients. Three (10.7%) patients presented with renal insufficiency, which was significantly associated with the age at presentation (P = 0.026). Ultrasound scan done in the postnatal period strongly suggested the diagnosis of posterior urethral valves in 22 (78.6%) patients in whom the posterior urethra was found to be dilated, associated with thick-walled urinary bladder and bilateral hydronephrosis. Trabeculations of the bladder was a constant feature on MCUG. Other features on MCUG included dilatation of the posterior urethra in 26 (92.8%), bladder diverticuli in 15 (53.6%) and unilateral and bilateral vesicoureteric reflux in 3 (10.7%) and 1 (3.6%) patient(s), respectively. The diagnosis of PUV obstruction which is often made late in our environment, is mainly by clinical, sonographic and MCUG features in the postnatal period. A majority of patients present late, with recurrent UTI.
