Purpose: To study the epidemiology and treatment modalities of urolithiasis at Urology Department of University Hospital of Cotonou. Materials and Methods: It was a retrospective and descriptive study over a 10 years period ranging from January 1st, 2004 to December 31st, 2013. One hundred and two patients who were hospitalized for symptomatic urolithiasis at the Urology Department of University Hospital of Cotonou were enrolled. Results: Hospital incidence of urolithiasis was 3.7%. Patients mean age was 39.6 years (extremes: 10 years to 73 years). Male to female ratio was 2.2. The main reason for consultation was renal colic for 81 patients (79.4%). Average duration of symptoms at presentation was 5 months (range: 1 day to 10 years). A total of 173 stones were identified with an average size of 12 mm (range: 1 mm to 95 mm). Calyceal stones were seen in 32.9% of cases, renal pelvis stones in 21.4% of cases, ureteral stones in 34.1% and bladder stones in 11.5% of cases. Open surgery was the main treatment for stones that could not be managed medically. 50.8% of patients underwent surgery with extraction of 116 stones. This represented 67.1% of all stones. 9 patients (8.8%) had expelled their stone during urination. The postoperative course was uneventful in 77.5% of cases. Conclusion: Modern treatment options for urolithiasis remain rudimentary in our health facilities. Open surgery is still the main stay of treatment in our countries with limited resources.

Intrauterine device represents the most reversible method of contraceptive worldwide. Its insertion is a medical procedure not free from complication. We report a rare case of intravesical migration of a copper intrauterine device inserted 18 months earlier in a 28-year-old multiparous woman. The patient presented with irritative lower urinary tract symptoms, and she was managed endoscopically. This case underscores the role of cystoscopy in irritative lower urinary tract symptoms post IUD insertion.

Body measurements and weights of animals of varying ages were recorded in White Fulani (Bunaji), Sokoto Gudali and N'dama breeds of cattle. Chest girth accounted for 86-96% of the variation in body weight in the three breeds. The linear regression coefficient of weight on chest girth in the N'dama differed significantly from the other two breeds. Within each breed, the regression coefficient of young animals was lower than those of older groups. The variables that contributed most to improving the prediction of weights when added to chest girth were rump length and body length. Animals with low body condition scores had lower regression coefficients of weight on chest girth than those with high scores.

Original data consisted of 31,777 records of progeny of 1442 sires for calvings between 1975 and 1983. Unadjusted means for milk yield (kg), days in milk, days dry, calving interval, days carried calf, and age at calving were 4281, 267, 88, 421, 145, and 36.6. Estimated total variance for first lactation milk yield by Henderson's method 3 was 1,385,436 kg 2 with sire and error variances accounting for 1.8 and 98.2%. Heritabilities for milk yield, lactation length, age at calving, and days carried calf were .07, .06, 2.59, and .01. High estimate for age was attributed to confounding of sires with season of calving. Genetic and phenotypic correlations between traits were milk and lactation length, .76 and .72; milk and age at calving, .17 and -.04; milk and days carried calf, -2.11 and .13; lactation length and age at calving, -.13 and -.06; lactation length and days carried calf, .87 and 16.; age at calving and days carried calf, -.60 and -.03. Sires with at least 10 daughters were evaluated by best linear unbiased prediction procedures. First lactation sire values for milk ranged from 359 to -340 kg with an average difference between sires of 12 kg. Sire values using all lactations ranged from 505 to -286 kg with an average difference between sires of 13 kg. Rank correlation between all and first lactation evaluations was .77.

Variance components and predicted sire values were estimated using 305-d projected and unprojected milk records of varying lengths. Original data consisted of 15,512 lactation records of daughters of 138 Jamaica Hope sires that calved between 1969 and 1981 in 38 commercial dairy herds in Jamaica. Classification of records had little effect on components of variance. Herd-year-season variance decreased from 36% using all lactations to 28% with first lactations only. Sire variance was consistently about 10%. Cow component of variance accounted for 17% of the total variation using all lactations and 36% using all lactations of cows with recorded first lactations. Heritabilities for milk by Henderson's method 1 were five to six times larger than estimated from method 3 due to sire by herd confounding. Predicted sire values were between +400 kg and -400 kg. Rankings of sires with at least 5 progeny were considerably influenced by record classification, especially for sires with highest predicted values. There was less influence on rankings when at least 10 progeny per sire were used while the range in predicted sire values was larger using first lactation records only.
