Overview of paediatric urology practice in lagos state university teaching hospital, Ikeja, Lagos, Nigeria.

INTRODUCTION: Paediatric urology is one of the subspecialities of urology, and in most climes, it is practised by the urologists and paediatric surgeons, and likewise in the Lagos State University Teaching Hospital (LASUTH). The urologists see and manage most of these cases in LASUTH. There has been no formal training in this subspeciality. However, both the urologists and paediatric surgeons in LASUTH have acquired some measure of skill and experience over time by virtue of the relatively high volume of the cases seen. This study is aimed at reviewing the practice of paediatric urology in the urology division of LASUTH and to advocate for formal training in an otherwise rare but direly needed subspeciality. PATIENTS AND METHODS: The ports of entry of paediatric patients with urologic conditions were assessed retrospectively over a 5-year period (2014-2018). The paediatric age range based on the Lagos State Government policy for health care is from birth to 12 years old. The ports of entry included the urologic outpatient department, paediatric and the adult surgical emergency units and the paediatric wards. Patients referred to and managed by the paediatric surgery division were excluded from this study. RESULTS: The total paediatric urology cases seen and managed by the urologist in LASUTH within the period of review were 421. A total of 363 paediatric urology cases were seen during the period under review, making up 7.96% of the urology cases seen at the surgical outpatient department. The most common cases managed were hypospadias, posterior urethral valves and hydronephrosis. A variety of other cases include priapism, circumcision and post-circumcision injuries, urethral prolapse, testicular torsion, cystic renal dysplasia, disorder of sexual differentiation and several others. Three hundred and seven surgical procedures were done in the period of review on 272 (64.6%) patients. CONCLUSION: There is a need for subspecialisation in paediatric urology to harness more specialists with a specific focus, training and interest in children and their urological conditions.

A prospective randomized comparative study of targeted versus empirical prophylactic antibiotics in the prevention of infective complications following transrectal ultrasound-guided prostate biopsy.

Background: It is established that antibiotic prophylaxis prevents infection following transrectal ultrasound-guided prostate biopsy. This study compares the infective complications in transrectal prostate biopsy (TRPB) in empirical versus targeted prophylactic antibiotics. Patients and Methods: Urine and rectal swabs were obtained prior to TRPB. They were randomized into targeted antibiotic (TA) and empirical antibiotic (EA) groups. TA had prophylactic antibiotics according to rectal swab culture, whereas EA had the standard parenteral ciprofloxacin. They were followed up weekly for 4 weeks. Chi-square or Fisher's exact tests were used to compare categorical variables, Student's "t"-test was used to compare means of numerical variables, and P < 0.05 was considered statistically significant. Results: One hundred patients were studied, fifty in each group. The mean age was 66 years, with men aged 60-69 years accounting for 50% of the study population. Providencia stuartii, Escherichia coli, and Citrobacter freundii were the most predominant bacteria identified in the prebiopsy rectal swab culture, with resistance to ciprofloxacin (57%) being much more common than that to levofloxacin (21%). Postbiopsy infection occurred in one (2%) patient in the TA group and five (10%) patients in the EA group. Difference in the infection rate between the two groups was statistically significant (P = 0.042). Three of the patients with postbiopsy infection in the EA group had urosepsis and required hospitalization. Fluoroquinolone-resistant bacteria were responsible for infection in all the six patients. TA reduced the risk of postbiopsy infection by 5.6 folds. Conclusion: TA was associated with a decreased risk of infection in TRPB.

RésuméContexte: Il est établi que la prophylaxie antibiotique prévient l'infection après une biopsie transrectale guidée par une échographie de la prostate (TRPB). Cette étude compare les complications infectieuses liées au TRPB entre antibiotiques prophylactiques empiriques et ciblés. Patients et méthodes: Des écouvillons urinaires et rectaux ont été obtenus avant le TRPB. Ils ont été randomisés en groupes d'antibiotiques ciblés (TA) et d'antibiotiques empiriques (EA). TA avait des antibiotiques prophylactiques selon la culture sur écouvillon rectal, alors que EA avait la ciprofloxacine parentérale standard. Ils ont été suivis chaque semaine pendant quatre semaines. Les tests exacts du chi carré ou de Fischer ont été utilisés pour comparer les variables qualitatives, le test de l'étudiant a été utilisé pour comparer la moyenne des variables numériques et P <-0,05 a été considéré comme statistiquement significatif. Résultats: Cent patients ont été étudiés; 50 dans chaque groupe. L'âge moyen était de 66 ans, les hommes de 60 à 69 ans représentant 50% de la population étudiée. Providencia Stuartii, Escherichia Coli et Citrobacter Freundii étaient les bactéries les plus prédominantes identifiées dans la culture du prélèvement rectal avant biopsie, la résistance à la ciprofloxacine (57%) étant beaucoup plus commune qu'à la lévofloxacine (21%). Une infection après la biopsie s'est produite chez 1 patient (2%) du groupe TA et 5 patients (10%) du groupe EA. La différence de taux d'infection entre les deux groupes était statistiquement significative (p = 0,042). Trois des patients présentant une infection post-biopsie dans le groupe EA présentaient une urosepsie et devaient être hospitalisés. Des bactéries résistantes à la fluoroquinolone étaient responsables de l'infection chez les six patients. L'AT réduit le risque d'infection après la biopsie de 5,6 fois. Conclusion: L'AT était associée à une diminution du risque d'infection dans le TRPB.

Outcome of Mainz II Pouch Urinary Diversion after Radical Cystectomy in Patients with Muscle-invasive Bladder Cancer: Our Experience.

INTRODUCTION: Mainz II pouch urinary diversion in patients with muscle-invasive bladder cancer is one of the options of continent urinary diversion following radical cystectomy (RC). We aim to report our experience and the outcome of our patients who had this procedure. PATIENTS AND METHODS: Patients who had RC and Mainz II pouch urinary diversion for muscle-invasive bladder cancer in our institution from 2007 to 2016 were evaluated. Variables analyzed included age, gender, stage of the disease, pathological grade and tumor types, complications, and survival status. RESULTS: There were 11 patients who had Mainz II pouch urinary diversion after RC for bladder cancer over a 10-year period. Four (36%) were male and 7 (64%) were female. The mean age of the patients was 58.6 (range, 52-65) years. The diseases were pT2, pT3, and pT4 in 2 (18%), 7 (64%), and 2 (18%) patients, respectively. Four (36%) had pelvic nodal metastasis. Nine (82%) had a histological diagnosis of transitional cell carcinoma, and two (18%) were squamous cell carcinoma (SCC). Ten (91%) patients had high-grade disease, whereas only 1 (9%) patient had low-grade disease. Short-term morbidities were electrolytes derangement, hypokalemia, and acidosis in 2 (18%) patients and pyelonephritis in 2 (18%) patient. The two patients with invasive SCC had recurrence and death within 12 months of surgery. At present, four of the patients are alive, and seven are dead. Survival till date ranged from 8 to 120 months (mean survival time was 48 months). All patients achieved day and night time continence, and there was no significant long-term morbidity from the method of urinary diversion. CONCLUSION: Mainz II pouch urinary diversion is safe and acceptable to most of our patients with good long-term results.

Outcome of radical retropubic prostatectomy at the Lagos State University Teaching Hospital.

BACKGROUND: Prostate cancer is the most commonly diagnosed cancer in men in Nigeria and most cases present when the disease is already in an advanced stage. Radical prostatectomy for early prostate cancer is therefore not a commonly performed operation by urologists in Nigeria. We have had training and significant experience in radical retropubic prostatectomy. We, therefore, report the outcome of our initial experience. MATERIALS AND METHODS: We review the record of men with early prostate cancer who had radical retropubic prostatectomy in our institution from 2007 to 2015. RESULTS: There were 34 men who had radical retropubic prostatectomy in the 8-year period of review. The youngest and oldest patients were aged 50 and 71 years, respectively. The mean age was 64.2 years. All the patients were diagnosed following 12-core ultrasound-guided transrectal prostate biopsy for elevated serum prostate specific antigen (PSA). The mean serum PSA was 15.3 (range 8.5-100.3) ng/ml. The disease was pT1, pT2, and pT3 in 6, 20, and 8 patients respectively. General anesthesia was employed in 28 (82.4%) patients and combined epidural and subarachnoid block anesthesia for 6 (17.6%) patients. The total duration of operation was 128-252 min (mean = 160 min). No blood transfusion was given in 5 (14.7%) patients while each of the remaining 29 (85.3%) patients had 2-5 units of blood intra- or post-operatively. There was no perioperative mortality. Complications include operation-induced erectile dysfunction in 12 (35.3%), major urinary incontinence in 1 (2.9%), lymphocele in 2 (5.9%), and reoperation due to anastomotic leak and right ureteric injury in 1 (2.9%). After a median follow-up of 42 months, disease recurrence has occurred in 3 (8.8%) patients 1 (2.9%) of whom has died of diabetic renal failure. CONCLUSION: Radical prostatectomy can be safely performed in men with early prostate cancer in Nigeria and should be offered to suitable patients.
