Enuresis and overactive bladder in sickle cell patients: a narrative review of the literature.

OBJECTIVE: The aim of this review is to clarify the prevalence, pathophysiology and clinical presentation of enuresis and overactive bladder in sickle cell patients. MATERIALS AND METHODS: This narrative review of the literature was conducted in March 2022 by running a search in PubMed, Embase, Scopus and Cochrane databases without publication date limitation, using the following keywords: enuresis or nocturia or overactive bladder or urinary incontinence or bedwetting and sickle cell. RESULTS: Eight cross-sectional studies were included, six of which had a non-sickle cell control population. The prevalence of enuresis in children and adolescents with sickle cell disease ranged from 20.3 to 49.4%. It decreased with age to 2.9% in adult sickle cell patients. Enuresis in sickle cell patients has been attributed to several causes, including lack of urine concentration with nocturnal polyuria, reduced bladder capacity, nocturnal bladder hyperactivity, sleep and/or respiratory disorders are likely causes of enuresis in sickle cell patients. The prevalence of overactive bladder is three times higher in sickle cell patients than in control groups. The latter is also observed three times more frequently in men who have had prior episodes of priapism. CONCLUSION: Enuresis and overactive bladder are common in sickle cell patients. Several mechanisms have been described to try to explain enuresis in sickle cell patients but overactive bladder seems to play a major role. Studies evaluating the efficacy of certain experimentally validated treatments must be carried out to improve the management of these complications which affect the quality of life of sickle cell patients.

[Epidemiological, etiological and evolutionary profile of vesico-vaginal fistulas in Senegal]. / Profil épidémiologique, étiologique et évolutif des fistules vésico-vaginales au Sénégal.

AIM: To evaluate the epidemiological, etiological and evolutionary profile of vesico-vaginal fistulas (VVF) in university hospitals in Senegal. PATIENTS AND METHOD: This is a retrospective, descriptive, single-center study, collecting the records of patients followed for VVF between January 2014 and December 2019 at the Urology and Andrology Department of the Centre hospitalier universitaire Aristide Le Dantec, Dakar, Senegal. The following parameters were studied: age, geographical origin, parity, and etiology of VVF. To assess the evolution of the epidemiological and etiological profile of VVF, we compared our results with those of series published by our structure. RESULTS: Forty-five (45) VVFs were identified over a period of 6 years. This represents an annual average of 7.5 fistulas. The average age was 40±15.13 years with extremes of 13 years and 75 years; 17 patients (37.8%) were older than 45 years. The average parity was 3 with extremes from 0 to 12 children. Multiparous women represented 68.8% of the patients. Obstetric VVF (OVF) was more frequent (48.9%) followed by iatrogenic VVF (33.3%). The mean age was higher in the IVF group compared to the VVF group (32 years) (P = 0.0004). Thirty patients were from the Dakar region and its suburbs (66.6%). The etiology of VVF did not vary according to the geographical origin of the patients (P=NS). VVF was frequently associated with the management of cervical cancer in 42.2% of cases. Comparison of our current data with previous series shows a reduction in the annual incidence of VVF. VVFs, although they have decreased significantly, are still predominant. There is a constant increase in the number of IVF. CONCLUSION: There is an evolution of the epidemiological and etiological profile marked by a decrease in the frequency of VVFs and an increase in that of IVFs. It is also worth noting the frequent association between cervical cancer and VVF. LEVEL OF EVIDENCE: Level 4: retrospective study.

Contained rupture of a left renal artery aneurysm: Report of a case.

Ruptured renal artery aneurysms are uncommon. Although the increased use of endovascular technologies, controversy persists over the management. Contained rupture may be more difficult to diagnose, hence delay the management. We report a case of contained rupture of renal artery aneurysm treated with selective embolization prior to nephrectomy.

Gossypiboma of renal compartment: A case report.

INTRODUCTION: Textiloma is a rare surgical complication. The location in the renal compartment is exceptional. The diagnosis can be difficult due to its rarity and the absence of clinical signs. The best treatment remains preventive by carefully counting the compresses and the operating fields at the beginning and end of the procedure. PRESENTATION OF CASE: We present a case report of a 71-year-old female patient with a high blood pressure under treatment. In this history, we noted a right nephrectomy by a lombotomy 6 years ago indicated for a mute kidney on a pyelo-ureteral junction syndrome and a drainage of a suppuration of this renal compartment a year after surgery. The patient was diagnosed with purulent discharge through the lombotomy site associated with lower back pain that had been present for 4 years. The patient then underwent an uro-CT scan which showed an oval formation of the right renal compartment suggestive of a textiloma. An exploratory right lombotomy was performed. And then the wetraction of the compresses followed by washing and closing had been done. The postoperative course was simple. DISCUSSION: The location in the renal compartment is exceptional. These may include compresses, surgical gauzes, sponges, cotton pads, etc. The inflammation caused by this foreign body will be responsible for an abscess in the event of infection. An evolution towards chronicity follows as long as the foreign body persists. Diagnosis and reoperation are often made during the same hospitalization period. Early imaging will help to make early diagnosis avoiding diagnostic wandering. The diagnosis was made late in our observation. However, the diagnosis can be difficult due to its rarity and the absence of clinical signs. CONCLUSION: Textiloma is a rare surgical complication. Renal localization, although rare, is "exceptional" of consequence. The best treatment remains preventive by carefully counting the compresses and the operating fields at the beginning and end of the procedure.

Gossypiboma migration into the bladder.

Gossypiboma is a dreaded complication following mainly abdomino-pelvic surgeries. The clinical presentation varies widely and is strongly associated with two factors: localization of the textiloma and type of the tissue reaction. Intravesical gossypiboma migration is rare and usually presents as recurrent urinary tract infections. We report a case of gossypiboma migration into the bladder that was treated by endoscopic extraction. The purpose of this report is to remind the importance of the prevention which must be the challenge rather than the treatment modalities.

Adult renal neuroblastoma: A case report.

Adult renal neuroblastoma is a rare condition, and a few cases have been previously described in the literature. Its prognosis is variable and the treatment suffer the lack of specific guidelines due to the low incidence. We report a case of adult renal neuroblastoma managed with nephrectomy and adjuvant chemotherapy. The purpose of this report is to update the knowledge available on this disease.

Evaluation of knowledge of priapism in sickle cell patients in Senegal.

PURPOSE: Erectile dysfunction is a dreadful complication of priapism especially with delay in diagnosis and management. The lack of awareness of priapism as a vaso-occlusive complication of sickle cell disease (SCD) is more concerning. The objective of this study was to evaluate the burden of priapism in adult Senegalese males adults with sickle cell disease. METHODS: A cross-sectional study was carried out amongst consecutive consenting males aged 18 years and older with SCD presenting to the in Haematology Department of the National Blood Transfusion Centre (Dakar, Senegal). All participants completed a questionnaire detailing knowledge on the definition of priapism, its association with SCD, consequences of untreated priapism and treatment options. RESULTS: A total of 219 participants completed the questionnaire. The mean age of the respondents was 27.1 years with a range of (18-54). Of the respondents, 78.5% (n = 172) did not have any knowledge of the term "priapism". After the term was explained, 38.4% (n = 84) thought that there may be a risk of developing priapism given the diagnosis of sickle cell disease. Among the participants, 41.5% (n = 91) reported having a history of priapism. Among all patients who experienced priapism, 36.3% (n = 33) did not seek medical attention with episodes of priapism. It was found that 48.4% (n = 106) of the participants thought there may be a risk of irreversible complications associated with priapism and a corresponding proportion, 42% (n = 92) thought this risk was time dependent. 36.5% (n = 80) of patients believed priapism could lead to erectile dysfunction. CONCLUSION: Priapism is a common complication of sickle cell disease in Senegalese adults which is not well known by sickle cell patients. The health authorities must undertake efforts to raise awareness of priapism as a complication amongst sickle cell patients.

[Testicular cancer is a rare condition in black people. We report 5 cases of testicular cancer in men with undescended testis]. / Cancer sur testicule non descendu intra-abdominal. A propos de 5 cas.

PATIENTS AND METHODS: We underwent a retrospective study of five cases of testicular cancer in undescended testis. The parameters of study were: age at diagnosis, circumstances of diagnosis, values of tumour markers, and pathological aspects of tumours after removal. The data were studied using the medical records of patients. RESULTS: Mean age was 30, 6 years (27; 34). Only 1 patient had a child at the time of diagnosis. All patients came to our clinic for a general state impairment associated to an abdominal palpable mass. The increase of the value of tumour markers was not constant. A capsular effraction was found in 3 cases with a rupture into the peritoneum. The pathology exam found 3 embryonic carcinoma and 2 seminomas, a lymph node involvement was found in 3 cases. CONCLUSION: The scarcity of these tumours should not make us ignore them. The early diagnosis of the tumour can be facilitated by testicular descent, because even if the descent of the testis does not prevent the tumour it can ease the follow-up.

[Leiomyosarcoma of the spermatic cord]. / Le léiomyosarcome du cordon spermatique.

Leiomyosarcomas of the spermatic cord are rare tumours. The authors report the case of a 65-year-old man presenting with painful mass of the left side of the scrotum with scrotal ulceration. Left transinguinal orchidectomy and left hemiscrotectomy were performed and histological examination of the operative specimen revealed leiomyosarcoma of the spermatic cord. No metastases were observed on thoracoabdominopelvic CT. One month after discharge from hospital, the patient presented with delayed healing and complementary scrotal resection and adjuvant radiotherapy were performed. Local and regional extension is frequently observed in leiomyosarcoma of the spermatic cord, justifying radical transinguinal orchidectomy with high ligation of the cord. Cases at greatest risk of recurrence (large tumour, early local recurrence, positive surgical margins) should be identified by multidisciplinary committees and may be eligible for adjuvant radiotherapy.

[Complications of circumcision. Report of 63 cases]. / Les complications de la circoncision. A propos de 63 cas.

OBJECTIVE: The aim of this study was to report complications of circumcision received in urologic center. MATERIAL AND METHODS: From a retrospective study during a period of 11 years, 63 cases of complications were noticed secondary to traditional circumcision (n = 45) or paramedics (n = 18). RESULTS: The different complications were: urethral fistulas (n = 41), total or partial glans amputation (n = 9), urethral stricture of the meatus (n = 8), penile pseudo elephantiasis (n = 2), penile denudation (n = 1), hemorragiae (n = 6) and septicaemia (n = 1). The authors underline clinical aspects of these complications and the problems of their treatment.

Etiology and current clinical characteristics of male urethral stricture disease: experience from a public teaching hospital in Senegal.

OBJECTIVE: To identify the etiology and current clinical characteristics of male urethral stricture disease (USD) in Senegal. PATIENTS AND METHODS: A retrospective and mono-centric study over a 10-year period (between January 1999 and December 2008) was carried out and included all male patients with USD admitted to the Urology Department of Aristide Le-Dantec Hospital (Dakar). RESULTS: We recorded 414 USD cases. The maximum annual incidence was observed in 2004, and from then, the incidence tended to decrease gradually. The mean age of patients was 43.7 ± 19.6 years (1-89 years), and 43% of patients were younger than 40 years old. The mean time from symptoms onset to the consultation was 20.1 ± 24.9 months (1-120 months). Most patients (42.2%) were admitted because they suffered dysuria. In 57.8% of patients, USD was diagnosed with complications. The most common site of stricture was at the bulbar urethra (72.7%). The length of the urethral stricture was smaller than 1 cm in 59.6% of patients, between 1 and 3 cm in 28.5% and between 3 and 5 cm in 7.7%. The stricture was longer than 5 cm in eight patients and was staged (multifocal) in nine patients. The etiology of urethral stricture was infectious in 63% of patients, traumatic in 13.7% and iatrogenic in 8.2%. The etiology was not identified in 14.9% of cases. The infectious etiology was urethritis in 259 cases and urogenital schistosomiasis in 12 cases. A study of the etiology according to stricture site showed that bulbar USD was infectious in 77.7% of cases and that all membranous USD cases were traumatic. CONCLUSION: Male urethral stricture in Senegal is often a sequela of gonococcal urethritis and is frequently detected because of infectious complications such as gangrene of the genitalia or urinary tract infections. Its prevention in this geographical region thus requires fighting against sexually transmitted infections and treating appropriately and effectively all urethritis.

Apoptosis and effects of intracavernous bone marrow cell injection in a rat model of postprostatectomy erectile dysfunction.

OBJECTIVES: To investigate the pathophysiology of postprostatectomy erectile dysfunction (pPED) in a rat model of bilateral cavernous nerve ablation (BCNA) and to assess the effects of local bone marrow mononuclear cell (BMMNC) injection on erectile dysfunction (ED) and cavernosal cellular abnormalities caused by BCNA. DESIGN, SETTING, AND PARTICIPANTS: This was an experimental study in Fisher rats with BCNA. INTERVENTION: Intervention included BNCA, electrical stimulation of the pelvic ganglion, and local BMMNC injection. MEASUREMENTS: Erectile responses to electric pelvic ganglion stimulation were studied. Cavernous tissue was examined to determine the cell types undergoing apoptosis and to detect changes in protein and gene expression of neuronal nitric oxide synthase (nNOS) and endothelial nitric oxide synthase (eNOS) using real-time quantitative polymerase chain reaction (RTQ-PCR) and Western blotting. The effects of local BMMNC injection on these parameters were studied. RESULTS AND LIMITATIONS: Diffuse apoptosis was noted in the connective tissue mesenchymal cells and vascular smooth muscle and endothelial cells. Compared with sham-operated controls, nNOS and eNOS levels were decreased after 3 wk and were normal (eNOS) or increased (nNOS) after 5 wk, suggesting spontaneous nerve regeneration. Despite nNOS recovery, erectile responses to electrical stimulation remained impaired after 5 wk, when mesenchymal cell apoptosis was the main persistent biologic abnormality. BMMNC injection decreased apoptotic cell numbers, accelerated the normalisation of nNOS and eNOS, and partially restored erectile responses at week 5. CONCLUSIONS: Massive cell apoptosis may play a key role in the pathophysiology of pPED. In this animal model, apoptosis persisted despite spontaneous nerve regeneration, suggesting that the course of BCNA-induced cell dysfunction was independent of reinnervation. BMMNC improved erectile function by inhibiting apoptosis and may hold promise for repairing penile cell damage caused by radical prostatectomy (RP).
