RESUMEN
OBJECTIVE: To review iatrogenic ureteric and urinary bladder injuries from obstetric and gynaecological surgeries treated in the urology department analysing; ureteric anatomy, aetiologic factors, diagnosis, treatment and outcomes. DESIGN: A retrospective study. SETTING: Institute of Urology, Kilimanjaro Christian Medical Center (KCMC), Moshi, Tanzania. SUBJECTS: Twenty three women were treated for iatrogenic ureteric and bladder injuries secondary to obstetric and gynaecological procedures in the department of urology between June 1994 and July 2004. RESULTS: Hysterectomy was the leading cause of ureteric injuries contributing to nine (47.4%) of the 19 ureteric injuries. Caesarian sections were the second leading cause and contributed 6(31.6%) of 19 ureteric injuries. Vesical vaginal fistula (VVF) repairs lead to two (10.5%) ureteric injuries one of which was bilateral. There was a case each (5.3%) from ovarian cystectomy and forceps delivery. There were only three cases of intra-operative diagnosis of ureteric injuries. There were four bladder injuries half of which came from hysterectomy. The leading definitive urological treatment for ureteric injury was ureteric re implantation and all kidneys were saved. CONCLUSION: Iatrogenic ureteric and bladder injuries from gynaecologic surgeries are globally rare but are liable to occur due to the inherent ureteric anatomic factors in the pelvis. Intra-operative diagnosis of injury is a rare feature. The practical principles to prevent and repair ureteric injuries have been presented and discussed. The true risk to the patient lies in delayed, missed diagnosis and inadequate treatment. Endourologic techniques offer an alternative diagnostic and treatment method for women previously injured in open pelvic surgeries.

In the Southern Highlands of Tanzania the prevalence of endemic goitre due to iodine deficiency is in the range of 90% and hypothyroidism in the range of 50% of schoolchildren. The present study confirms these data and documents the beneficial effect of Lipiodol injections on thyroid function in children around the age of puberty compared with untreated children from the same villages. On the other hand, a decrease in the prevalence of goitre could not be shown. A beneficial effect is shown for infants of mothers who received iodine during pregnancy. It seems that this form of supplementation is sufficient for breast fed children for more than three years, even when a second child has been delivered in the meantime. In contrast, older siblings of these babies may become hypothyroid when breast feeding is stopped. The determination of thyroid autoantibodies in iodine treated and untreated children and in young adults showed no increasing prevalence of positive findings thus excluding iodine induced chronic thyroiditis at least in the young target population.

UNLABELLED: The Ukinga and Uwanji regions, located in the southern highlands of Tanzania, were studied for the degree of iodine deficiency and the incidence of goitre and hypothyroidism, respectively. A urinary iodine excretion as low as 17.6 +/- 9.3 micrograms/g creatinine was observed in Wangama village. The mean goitre prevalence in 27 villages in Uwanji ranged between 65 and 96% (n = 3031 schoolchildren). Of 681 pregnant women from Ukinga 79.6% had goitre. The prevalence of cretinism as estimated on clinical criteria was 3% in Magoye (Uwanji). A normal serum TSH (below 2.1 mU/l) was observed in only 12 out of 66 school children before iodine prophylaxis, whereas the T4/TBG ratio was decreased in 36 of 63 cases. Blood spot TSH levels in newborn infants (n = 219) from mothers without iodine supplementation were above 12 mU/l in 45%. In contrast, only 20.3% of the newborn (n = 118) had elevated blood spot TSH (p less than 0.002) when the mothers had received an iodised oil injection during pregnancy. Most of the newborn (n = 18; 75%) of the latter group with elevated TSH (n = 24) came from mothers who had received the iodine injection only 1-25 days before delivery. Maternal iodine prophylaxis in late pregnancy does not increase the rate of neonatal hypothyroidism. CONCLUSIONS: It has been confirmed that severe iodine deficiency resulting in endemic goitre, cretinism, and hypothyroidism is prevalent in the regions studied. Dried blood spot TSH determinations may serve as an index for the efficiency of iodine prophylaxis programmes. Such a programme was carried out with relatively little expenditure and effort on a large scale basis.
