Every year, 6000 women die due to complications of pregnancy and childbirth, uterine rupture accounts for about 8% of all maternal deaths. The objective of this study was to establish the incidence of uterine rupture, predisposing factors, maternal and fetal outcomes and modes of management at a regional referral university hospital in Southwestern Uganda. Methods: Case-control design of women with uterine rupture during 2005-2006. Controls were women who had spontaneous vaginal delivery or were delivered by caesarean section without uterine rupture as a complication. For every case, three consecutive in-patient chart numbers were picked and retrieved as controls. All available case files, labour ward and theater records were reviewed. Results: A total of 83 cases of uterine rupture out of 10940 deliveries were recorded giving an incidence of uterine rupture of 1 in 131 deliveries. Predisposing factors for uterine rupture were previous cesarean section delivery(OR 5.3 95% CI 2.7-10.2), attending < 4 antenatal visits (OR 3.3 95% CI 1.6-6.9), parity ≥ 5(OR 3.67 95% CI 2.0-6.72), no formal education (OR 2.0 95% CI 1.0-3.9), use of herbs (OR15.2 95% CI 6.2-37.0), self referral (OR 6.1 95% CI 3.3-11.2) and living in a distance >5 km from the facility (OR 10.86 95% CI 1.46-81.03). There were 106 maternal deaths during the study period giving a facility maternal mortality ratio of 1034 /100,000 live births, there were 10 maternal deaths due to uterine rupture giving a case fatality rate of 12%. Conclusion: Uterine rupture still remains one of the major causes of maternal and newborn morbidity and mortality in Mbarara Regional referral Hospital in Western Uganda. Promotion of skilled attendance at birth, use of family planning among those at high risk, avoiding use of herbs during pregnancy and labour, correct use of partograph and preventing un necesarry c-sections are essential in reducing the occurences of uterine repture.

This study was conducted to estimate the potential cost-effectiveness of achieving universal access to modern contraceptives in Uganda by implementing a hypothetical new contraceptive program (NCP) from both societal and governmental (Ministry of Health (MoH)) perspectives. Methodology/Principal Findings: A Markov model was developed to compare the NCP to the status quo or current contraceptive program (CCP). The model followed a hypothetical cohort of 15-year old girls over a lifetime horizon. Data were obtained from the Uganda National Demographic and Health Survey and from published and unpublished sources. Costs, life expectancy, disability-adjusted life expectancy, pregnancies, fertility and incremental cost-effectiveness measured as cost per life-year (LY) gained, cost per disability-adjusted life-year (DALY) averted, cost per pregnancy averted and cost per unit of fertility reduction were calculated. Univariate and probabilistic sensitivity analyses were performed to examine the robustness of results. Mean discounted life expectancy and disability-adjusted life expectancy (DALE) were higher under the NCP vs. CCP (28.74 vs. 28.65 years and 27.38 vs. 27.01 respectively). Mean pregnancies and live births per woman were lower under the NCP (9.51 vs. 7.90 and 6.92 vs. 5.79 respectively). Mean lifetime societal costs per woman were lower for the NCP from the societal perspective

It occurs in areas where access to care at childbirth is limited, or of poor quality and where few hospitals offer the necessary corrective surgery. Methods This was a prospective observational study where all women who attended Mbarara Regional Referral Hospital in western Uganda with obstetric fistula during the study period were assessed pre-operatively for social demographics, fistula characteristics, classification and outcomes after surgery. Assessment for fistula closure and stress incontinence after surgery was done using a dye test before discharge Results Of the 77 women who were recruited in this study, 60 (77.9%) had successful closure of their fistulae. Unsuccessful fistula closure was significantly associated with large fistula size (Odds Ratio 6 95% Confidential interval 1.46-24.63), circumfere...

Abortion seekers usually go to illegal, hidden clinics where procedures are performed in unhygienic environments by undertrained practitioners. These abortions, which are usually unsafe, lead to a high rate of severe complications and use of substantial, scarce healthcare resources. This study was performed to estimate the costs associated with induced abortions in Uganda. Methods: A decision tree was developed to represent the consequences of induced abortion and estimate the costs of an average case. Data were obtained from a primary chart abstraction study, an ongoing prospective study, and the published literature. Societal costs, direct medical costs, direct non-medical costs, indirect (productivity) costs, costs to patients, and costs to the government were estimated. Monte Carlo simulation was used to account for uncertainty. Results: The average societal cost per induced abortion (95% credibility range

In Uganda about 2,275 new cervical cancer deaths occur annually. The main objective of the study was to describe the magnitude, trends, clinical stage on presentation and show the importance of cervical cancer prevention and radiotherapy services at Mbarara Regional Referral Hospital. Methods: This was a descriptive cross-sectional study. In the first phase of the study, leading cancers at Mbarara Regional Referral Hospital were determined. In the second phase of the study, the burden of cervical cancer on the gynecological ward was determined. In the third part of the study the trends of cervical cancer over a ten year period was determined. In the fourth phase of the study the effects of acetic acid screening on the trends of cervical cancer was determined. Results: With a prop...

Surgery, which is aimed at reconstruction of a vagina of adequate length and width to serve the function, is the main method of treatment. Many methods for vaginal reconstruction have been described but each has its complications and limitations. The most commonly preferred procedure for treating this condition is the McIndoe vaginoplasty which involves dissection into the recto-vesical space, inserting two split thickness skin grafts folded over a mold in this newly created space and regular dilatation of the neovagina postoperatively to avoid stenosis. However surgeons with this expertise in this part of the world are rare to find and where they are available, the special molds on which to fold the skin grafts into the neovaginal space are not readily available. Case presentation: A 21-year-old female with vaginal agenesis was operated on using a modification of the McIndoe procedure using a cylinder of a 60cm 3 syringe as a vaginal mold/form and kept in place. We left a Foley in place for 10 days and we did a dye test after removing the syringe to ensure that there was no leakage resulting from fistula formation. Conclusion: The operation was successful and on subsequent monthly reviews of the patient, she has a patent functional vagina of about 9 cm in length at 8 months after the operation with resumption of sexual intercourse.

The aim of this study was to investigate the role of individual and health facility factors and the risk for obstructed labour and its adverse outcomes in southwestern Uganda. Methods: A review was performed on 12,463 obstetric records for the year 2006 from six hospitals located in southwestern Uganda and 11,180 women records were analysed. Multivariate logistic regression analyses were applied to control for probable confounders. Results: Prevalence of obstructed labour for the six hospitals was 10.5% and the main causes were cephalopelvic disproportion (63.3%), malpresentation or malposition (36.4%) and hydrocephalus (0.3%). The risk of obstructed labour was statistically significantly associated with being resident of a particular district [Isingiro] (AOR 1.39, 95% CI: 1.04-1.86), with nulliparous status (AOR 1.47, 95% CI: 1.22-1.78), having delivered once before (AOR 1.57, 95% CI: 1.30-1.91) and age group 15-19 years (AOR 1.21, 95% CI: 1.02-1.45). The risk for perinatal death as an adverse outcome was statistically significantly associated with districts other than five comprising the study area (AOR 2.85, 95% CI: 1.60-5.08) and grand multiparous status (AOR 1.89, 95% CI: 1.11-3.22). Women who lacked paid employment were at increased risk of obstructed labour. Perinatal mortality rate was 142/1000 total births in women with obstructed labour compared to 65/1000 total births in women without the condition. The odds of having maternal complications in women with obstructed labour were 8 times those without the condition. The case fatality rate for obstructed labour was 1.2%. Conclusions: Individual socio-demographic and health system factors are strongly associated with obstructed labour and its adverse outcome in southwestern Uganda. Our study provides baseline information which may be used by policy makers and implementers to improve implementation of safe motherhood programmes.

In Uganda, the WHO-MDG 5 (aimed at reducing maternal mortality by 75 % between 1990 and 2015) has not been attained. The current maternal mortality ratio (MMR) in Uganda is 438 per 100,000 live births coming from 550 per 100,000 in 1990. This study sets out to find causes and predictors of maternal deaths in a tertiary University teaching Hospital in Uganda. Methods: The study was a retrospective unmatched case control study which was carried out at the maternity unit of Mbarara Regional Referral Hospital (MRRH). The sample included pregnant women aged 15-49 years admitted to the Maternity unit between January 2011 and November 2014. Data from patient charts of 139 maternal deaths (cases) and 417 controls was collected using a standard audit/data extraction form. Multivariable logistic regression analysis was used to assess for the factors associated with maternal mortality. Results: Direct causes of mortality accounted for 77.7 % while indirect causes contributed 22.3 %. The most frequent cause of maternal mortality was puerperal sepsis (30.9 %), followed by obstetric hemorrhage (21.6 %), hypertensive disorders in pregnancy (14.4 %), abortion complications (10.8 %). Malaria was the commonest indirect cause of mortality accounting for 8.92 %. On multivariable logistic regression analysis, the factors associated with maternal mortality were: primary or no education (OR 1.9; 95 % CI, 1.0-3.3); HIV positive sero-status (OR, 3.6; 95 % CI, 1.9-7.0); no antenatal care attendance (OR 3.6; 95 % CI, 1.8-7.0); rural dwellers (OR, 4.5; 95 % CI, 2.5-8.3); having been referred from another health facility (OR 5.0; 95 % CI, 2.9-10.0); delay to seek health care (delay-1) (OR 36.9; 95 % CI, 16.2-84.4). Conclusions: Most maternal deaths occur among mothers from rural areas, uneducated, HIV positive, unbooked mothers (lack of antenatal care), referred mothers in critical conditions and mothers delaying to seek health care. Puerperal sepsis is the leading cause of maternal deaths at Mbarara Regional Referral Hospital. Therefore more research into puerperal sepsis to describe the microbiology and epidemiology of sepsis is recommended.
