Clinical Presentation, Therapeutic Aspects and Results of Urogental Prolapse in Yaounde ()
1. Introduction
Urogenital prolapse is defined as a protrusion of one or more abdomino-pelvic contents in to the vaginal cavity. This is an exclusively female condition that can affect the anterior or posterior vaginal walls, the uterus or the vaginal vault [1] (Figure 1). It is a common condition with a worldwide prevalence ranging from 2.9% to 11.4% [2] . The cumulative incidence over the age of 70 is about 11% [3] . A study in Canada found that urogenital prolapse accounted for 3% of all gynaecological consultations [3] . In Africa, urogenital prolapse is the subject of several under-documented consultations. In Morocco, the prevalence of urogenital

prolapse was found to be 30.8% in a population aged between 20 and 59 [4] . An Ethiopian study showed that genital prolapse accounted for 19.9% of all gynaecological operations [5] . In Cameroon, the prevalence of urogenital prolapse is estimated at 10.6% [6] . This condition has now become a real public health problem because of its frequency, cost and major impact on the quality of life with repercussions on urinary, sexual and digestive function [3] . Along with urinary incontinence, it is one of the most frequent reasons for consultation in gynaecology [5] . It is a functional pathology that affects the quality of life of many women, especially the elderly, but does not spare younger patients [6] [7] . To the best of our knowledge, there is a limited data on the clinical and therapeutic aspects of urogenital prolaps in Yaounde. Therefore, the purpose of the study is to describe the clinical presentation, therapeutic aspects and results of urogenital prolapse in Yaounde, Cameroon.
2. Methodology
This was a descriptive cross-sectional study with retrospective data collection carried out at the Yaounde Gynaecological Obstetric and Pediatric Hospital (YGOPH) and the Yaounde Central Hospital (YCH) over a period of 05 months (from February 2022 to June 2022). All women aged ≥30 years and all women with documented urogenital prolapse admitted to the maternity and/or urology departments of these two health facilities were included. Data were collected using a pre-designed data sheet with questions organized into three sections: socio-demographic data, clinical signs and therapeutic aspects. The questionaire was validated and the reliability tested prior to data collection. The information collected was analyzed using IBM SPSS (statistical package for social sciences) software version 23.0 and the data were reported as mean, standard deviation, frequencies and percentages.
3. Results
A total of 6850 records were reviewed and we recorded 56 cases of urogenital prolapse. The overall prevalence was 0.8% (Figure 2). The prevalence was 0.6% at the Yaounde Central Hospital and 1.2% at the Yaounde Gynaecological-Obstetric and Paediatric Hospital.
3.1. Description of Socio-Demographic Characteristics
Majority of the patients were aged >55 years (32%). The most common level of education was primary education (48%). Majority of the participants were housewives (40%). Majority of the patients were from the West (26%) (Table 1).
3.2. Description of Clinical Characteristics
Pelvic heaviness was the most common reason for consultation (54%) and gyneco-obstetric history was dominated by menopause (48%). Most patients had multiple gestures and the mean parity was 4.1 ± 1.1 ranging from 0 to 13 (54%) (Table 2).

About 20% of patients had undergone caesarean section in the past. Diabetes was common in 30% of the study population. The most common clinical sign was cystocele (56%). Eighteen patients (36%) were classified as first-degree and twenty-nine patients (58%) had an anterior location of the condition (Table 3).

3.3. Therapeutic Characteristics
3.3.1. Hospitalisation
The average length of hospital stay was 7.9 ± 3.7 days (Figure 3). The mean

duration of the catheterisation was 3.02 ± 2.9 days. The short-term outcome was favourable in 98% of cases and unfavourable in 2%.
3.3.2. Treatment and Complications
Perineal physiotherapy was the most applied medical treatment (66.7%). Surgical treatment was carried out in 34 patients (68%) predominantly anterior colporraphy. The most common approach being vaginal approach in 67.6% of cases. The most common surgical technique was the triple perineal operation with vaginal hysterectomy (29.4%). Intra-operative complications were haemorrhage (14.7%) and lower urinary tract injury (5.9%), while infection (8.8%) and haemorrhage were the most common post-operative complications (5.9%) (Table 4).
3.3.3. Prognosis
The anatomical and/or functional results and the degree of patient satisfaction were respectively: fair (65.6%), average (50%) and average (53.1%) at 3 months; at 6 months, good (52.2%), good (60.9%) and good (60.9%) and at 12 months, good (47.1%), good (70.6%) and good (70.6%) (Table 5).
4. Discussion
4.1. Prevalence
A total of 56 cases of urogenital prolapse were found. This represents 0.8% of our gynaecological consultations. This is similar to the 1.09% found by Coulibaly et al. in Bamako, Mali in 2011, but lower than the 12.7% and 5.2% found by Camara et al. in Mali in 2022 and De Tayrac et al. in France in 2013 respectively [8] - [12] . This difference may be attributed to the difference between the study populations and the sample size. The frequency of urogenital prolapse varies from one country to another.

4.2. Socio-Demographic Characteristics
This condition affects women of all ages. In our series, the youngest woman was 21 years old and the oldest 72 years old. However, the age group most affected were women aged 55 years and above. The mean age was 45.8 ± 17 years. This result is similar to that observed by Gakou et al. in Mali in 2021, who had a mean age of 44.7 years, with extremes of 17 and 80 years, with a majority of patients aged 46 [9] . However, our result differs from those of Olsen et al. [10] , who had a mean age of 61.8 years, and Wetzel et al. in Mexico, who found an average age of 55 years [11] . This difference could be explained by our socio-cultural differences, the etiology of the prolapse, the standard of living and the density of our
population.
In our study, about 40% of the study population were housewives. This observation is similar to that made by Camara et al. in Mali in 2022, who reported that 62.4% of patients were housewives [12] . The etiology of the urogenital prolapse could be explained by the many strenuous jobs (in the fields, carrying heavy loads, etc.) that African women do on a daily basis.
4.3. Clinical Features
All patients presented with symptoms related to urogenital prolapse. The main reason for consultation in our study was pelvic heaviness (54%). This result is similar to that of Belachkar et al. in Morocco in 2016, who found pelvic heaviness to be the main reason for consultation in 50% [13] . On the other hand, in Mali, Coulibaly et al. in 2010 found vulvar swelling to be the main complaint in 49.2% of patients. In 2022, Camara et al. found a sensation of an intra-vaginal ball to be the main reason for consultation in 94.5% of patients [12] [14] .
The most common clinical sign was cystocele in 56% of patients. Gakou et al. in Mali in 2021 reported 97.15 cases of cystocele. Thirty-six percent of our patients were at the first degree stage of prolapse, which differs from the predominance of the 3rd degree in 88.6% of cases reported by Camara et al. [12] . This could be attributed to the fact that their patients only consulted when the prolapse became very troublesome. The majority of our patients (58%) presented with an anterior stage prolapse, similar to the 95% prevalence of anterior stage prolapse reported by Belachkar et al. [13] . Coulibaly et al. carried out a cytobacteriological examination of urine in 66.7% of their patients [14] . In our study, 60% of our patients did urine culture and antibiotic sensitivity which were non-sterile.
4.4. Therapeutic Aspects
The aim of treatment for genital prolapse is to correct the related pelvic static disorders by restoring normal vaginal anatomy and physiology, to prevent recurrence and to avoid complications. Therefore, the attending physician must do everything possible to achieve not only anatomical correction but also restoration and/or conservation of bladder, sexual and fertility functions.
The most common treatment modality in our series was surgical treatment (68%). Vaginal approach was done in about two-thirds of the patients and triple perineal operation with vaginal hysterectomy was the most common surgical technique (29.4%). Our findings were similar to Diouf et al. [15] . The vaginal route is the operation of choice for genital prolapse, as it allows the three usual components of prolapse to be treated. This approach is frequently used because of the possibility of being performed under locoregional anaesthesia (spinal anaesthesia), short duration of surgery, reduced length of hospital stay, favourable post-operative period, the absence of parietal complications, less post-operative pain with a low financial cost and the possibility of combining additional perineal procedures if required. This surgical technique also reduces thromboembolic complications (operations with raised legs). The average hospital stay was 7.9 days, which is similar to the 4 days reported by Camara Y et al. [12] . Our patients were hospitalised for approximately 3.02 days with a urinary catheter in place, similar to the 2.3 days reported by Coulibaly B et al. [14] .
4.5. Prognosis
In our study, hemorrhage and urinary tract injury were the two most common intraoperative complications. These findings were similar to those reported by Diouf A.A et al. and Coulibaly B et al. [14] [15] . However, Gakou A et al. reported no intraoperative complications [9] . Two types of post-operative complications were recorded in our series, namely infection (8.8%) and hemorrhage (5.9%). This result is in line with the postoperative complications reported by Camara et al. and Diouf AA et al., who found infection (0.4%) and bladder injury (4.9%) respectively. On the other hand, Gakou A et al. and Coulibaly B et al. had no post-operative complications [9] [14] .
We found out that in the 3 months post-operative follow-up, the anatomical result was average in 65.6% of cases; the functional result was average in 50% and the half of the patients were moderately satisfied. This result differs from that of Coulibaly M et al. in Bamako, Mali, in 2011, who found 93.1% good anatomical results and 82.7% good functional results [14] .
5. Conclusion
We conclude that women above 55 years of age are at risk of having urogenital prolapse. Cystocele is the predominant clinical form. The mainstay of treatment is surgery. The prognosis was relatively good and the patients’ quality of life significantly improved.
