Introduction: It has long been understood that sleep is a necessary therapeutic element of human physiology and is crucial for healthy functioning, mental health, and quality of life. Medical students frequently minimize their sleep and habits to cope with their workload and their stressful lives, which has a negative influence on both mental health and academic performance. The purpose of this study was to evaluate the prevalence of stress and its effect on sleep quality among medical students (in both the preclinical and clinical years) at Jazan University in Saudi Arabia., Materials and Methods: A cross-sectional research design was applied in this study. The sample constituted medical students at Jazan University, Jazan region, Saudi Arabia. A self-administered online survey was distributed actively to measure the variables of interest., Results: This study examined the sleep quality and psychological distress among 347 students. The findings revealed that a significant proportion of students experienced sleep difficulties, with 52.8% reporting mild sleep problems and 46.6% reporting moderate sleep difficulties. In addition, a notable percentage of participants (28.2%) reported very high psychological distress, while 27.4% experienced severe psychological distress., Conclusions: This study found that medical students had a high level of stress and poor sleep quality, which led to unhealthy habits, such as consuming many energy drinks. Hence, it is recommended that concerns should be addressed to minimize the risk of developing chronic illnesses., (Copyright © 2024 Copyright: © 2024 Annals of African Medicine.)

Objectives: Suburethral sling is the gold standard treatment for stress urinary incontinence (SUI). Short-term cure rates are high, but only few studies are available for longer assessment after transobturator tape procedure. The objectives of this study were to assess mid-term functional outcome for Monarc(®) transobturator tape after initial success, and to identify risk factors for recurrence., Material and Methods: We conducted a single centre retrospective study (2004-2013) on consecutive women with SUI who underwent Monarc(®) transobturator tape procedure and were initially cured at the postoperative medical consultation. Pre- and postoperative data (age, weight, height, body mass index, hormonal status, surgical history, associated organ prolapse [Baden and Walker], associated urinary symptoms, postoperative complications [Clavien-Dindo]) were extracted from the electronic medical record. Subjective cure was defined by a score of zero from the ICIQ-SF questionnaire, no second intervention for recurrent SUI and no need for pads at latest news. Statistical analysis was performed using SAS(®) v9.3 (P<0.05)., Results: One hundred and thirty-three consecutive women underwent TOT Monarc(®) procedure, and 125 women were cured in the short-term. Among these women, 103 (82%) were available for mid-term evaluation. Sixty-four women (62%) had pure stress urinary incontinence. The mean follow-up period was 51 months [2-119]. At last follow-up, cure rate was 61%. Seventy-eight percent of women with recurrent urinary incontinence had SUI. Other women had mixed urinary incontinence (3/40), or de novo urgency (6/40). In univariate analysis, we could not identify pejorative prognostic factors for mid-term failure., Conclusion: In our experience, mid-term functional outcome after Monarc(®) transobturator tape procedure seems to deteriorate. After 4 years of follow-up, 61% of the women who were initially cured were still free from any leakage., Level of Evidence: 4., (Copyright © 2016 Elsevier Masson SAS. All rights reserved.)

Purpose: Prospective evaluation of bladder tumor targeting by Hexvix(®) fluorescence., Patients and Methods: From September 2008 to April 2012, 107 patients have been evaluated using Hexvix(®) technique (blue light) for typically papillary bladder tumor or suspected bladder tumor. Clinical and pathological data have been collected prospectively and patients have been classified using EORTC score., Results: From the 107 patients, 67 have been identified with bladder cancer and 328 samples have shown positive fluorescence in blue light. Compared to white light, 13 additional tumors have been diagnosed by Hexvix(®) for 11 patients: Cis (n=6), LMP (n=3), pTa low grade (n=3), pT1 low grade (n=1) (P=0.003). The false positive rate for Hexvix(®) was 53.4% versus 52% for white light. Previous TCC history, multifocality and EORTC score for recurrence and progression have been associated with better bladder cancer targeting by Hexvix(®) (P=0.007; P=0.01; P=0.03; P=0.04)., Conclusion: In our experience, Hexvix(®) targeting was associated with better diagnosis for bladder cancer with 9% (13/144) of new positive samples (P=0.003). In our study, false positive rate is a critical point (53.4%). Multifocality, previous TCC, and EORTC score for recurrence and progression might allow selecting patients to be targeted by Hexvix(®)., (Copyright © 2012 Elsevier Masson SAS. All rights reserved.)

Objective: Evaluate epidemiology, diagnosis and outcome of de novo renal cell carcinoma in renal transplanted patients., Patients and Method: From June 1989 to December 2007, 824 renal transplantations were carried out and followed in annual consultation by an urologist with abdominal echography or tomodensitometry. The suspect renal lesions were treated by a widened nephrectomy. Incidence, diagnosis, treatment, histological type, and outcome of all patients were analysed., Results: Thirty-three patients had nephrectomy for suspect renal lesions. Twenty-two de novo tumours of native kidneys among 21 patients were diagnosed (15 renal clear cell carcinoma and seven papillary tumours) with mean time after transplantation of 25,6 months (2.3-105.5). All tumours were classified pT1aN0M0. Only one patient died at 8 months of metastatic dissemination of a papillary tumour classified initially pT1aN0M0. All the other patients are alive with mean follow-up of 34.8 months (2.8-113.9). Specific survival to 5 years was 93.3%., Conclusion: The increase risk of tumour at the renal transplanted patient led to propose in the event of suspect lesions of the native kidneys, a widened nephrectomy. In our series, 65% of the operated patients carried a cancer. The good forecast of these localized tumours justifies a regular radiological monitoring and an aggressive therapeutic attitude despite of absence of tumours in 35% of the transplanted patients., (Copyright © 2010 Elsevier Masson SAS.

Objective: To determine the sensitivity and specificity of MRI to distinguish between superficial and invasive transitional cell bladder cancer., Material and Methods: Sixty patients (52 men and eight women) with a mean age of 66.8 years were assessed by bladder MRI between May 2002 and November 2005 for a primary bladder cancer diagnosed by endoscopy, followed by transurethral resection and histological examination of the bladder cancer. Patients presenting a discordance between MRI findings and histological examination were analysed., Results: Imaging and pathology staging was concordant for 49 bladder cancers (40 superficial and nine invasive). Ten tumours considered to be invasive on MRI were superficial on histological examination and six of them relapsed at the resection scar at one or three months. The sensitivity of MRI was 80% for a specificity of 90% and a positive predictive value of 97.5%., Conclusion: MRI is a reliable examination to confirm the superficial nature of bladder cancer. When MRI and histological examination of a bladder cancer resection specimen are discordant, second look surgery is recommended to treat residual disease, which was present in 60% of cases in the present series.

Objective: To evaluate the proportion of surgical workload, in terms of time and number of procedures, devoted to chronic renal failure surgery in an urology and transplantation operating room., Material and Methods: Analysis of the operative activity of the urology and transplantation operating room of Amiens Hospital over a period of one year (2003), by evaluating the number of procedures and the operating room occupation time (time between entry and exit from the operating room) recorded on ecology forms completed for each operation. Procedures performed in this operating room comprise conventional adult urological surgery and chronic renal failure procedures (from creation of venous access sites for haemodialysis to treatment of complications of renal transplantation)., Results: Surgical management of chronic renal failure in the operating room represents 22.6% of all procedures and 30.1% of the operating room occupation time. 69% of the renal transplantation operating time and 95% of kidney harvesting operating time are performed on an oncall basis., Conclusion: Operative activity related to chronic renal failure represents almost one third of the total surgical workload of a department managing this disease. These data justify the allocation of additional surgical resources adapted to this activity that is growing in parallel to the number of patients with chronic renal failure.

Uretero-arterial fistulas are exceptional complications: only about forty cases have been reported in the literature. The authors report new two cases of fistula between the common iliac artery and the ureter. One fistula occurred in a context of prolonged ureteric stenting after radiotherapy and pelvic surgery for cancer of the uterus, and the other occurred after an aorto-bifemoral allograft. These fistulas generally occur in a particular clinical context, associating several aetiological factors. The clinical presentation is dominated by often massive and intermittent haematuria. The most useful diagnostic examinations are retrograde ureteropyelography and arteriography. The proposed treatment options (nephrectomy, vascular bypass graft and even embolization) depend on the urgency of the situation and involve both the blood vessel and the urinary tract. The prognosis depends on early diagnosis, but preventive measures can be envisaged to decrease the risk of appearance of these fistulas in high-risk patients.

Transitional cell carcinoma of the kidney with caval tumour thrombus is extremely rare. The authors describe the radiological signs suggesting the preoperative diagnosis and guiding the therapeutic approach. They present the case of a 51-year-old patient with excluded caliceal stones, and review 17 cases published over a period of 24 years during which considerable progress has been made in radiological investigations. Only CT appears to be able to indicate this aetiology and allows retrograde ureteropyelography looking for a tumour of the urinary tract. MRI provides the best assessment of tumour involvement of the inferior vena cava. Nephroureterectomy with excision of a perimeatal bladder cuff and cavotomy is the only oncological surgical procedure, despite the extremely poor prognosis.

The authors report a retrospective series of 114 radical prostatectomies performed over a ten-year period. This study was designed to investigate the factors likely to cause complications in order to prevent them. Stenosis of the vesicourethral anastomosis was observed in 22 patients and represented the commonest complication (19.2%). It generally occurred before the 12th month, while late stenoses. An anastomotic leak after removal of the bladder catheter appears to be the most significant factor. The decreasing incidence of these stenoses over the ten-year study period illustrates the role of operator experience. The most effective treatment for these stenoses is mono-incision which, completed by dilatation sessions, prevents recurrence without compromising continence.

Fifty-seven bladder neck incisions were studied with a minimum follow-up of 5 years. The results published after one year were very satisfactory, but became more disappointing after 5 years, with a 38.7 reoperation rate. The weight of the prostate appears to be the determining factor. The indications, 5 years ago, were much wider than they are today, with prostate weights of up to 45 g on digital rectal examination. This type of operation should now be reserved for young subjects wishing to retain antegrade ejaculation with a prostate not exceeding 20 to 30 g and in high surgical risk patients unsuitable for transurethral resection.

The authors report a rare case of bilateral ureteric stenosis associated with necrotic infiltration due to acute alcoholic pancreatitis. The obstruction was caused by bilateral ureteric fibrosis with calcified incrustations on the right side and massive obstructive calculi on the left side. Only one faintly similar case has been reported in the literature out of 17 cases of unilateral or bilateral ureteric stenosis complicating acute or chronic pancreatitis.

Extracorporeal shock wave lithotripsy (ESWL) has produced dramatic advances in the surgical management of urinary calculi. However this new procedure could induce deleterious effects as loss of renal function and hypertension. Animal studies show that ESWL induces focal areas of necrosis and subsequent fibrosis in renal tissue. In humans, imaging technics demonstrate renal alterations in 80% of the patients. Acute renal hemodynamic and functional changes is frequent but transient in most of the cases. Some studies have shown a tendancy to an increase in blood pressure related to a decrease in renal plasma flow in one study. However most of these results are based on retrospective surveys of blood pressure and renal function. Therefore prospective clinical trials are needed to investigate the important questions of ESWL-induced hypertension and decrease renal function.

The authors report a case of renal hydatid disease, a rare disease in France. After reviewing the recent data of the literature, they stress the value of computed tomography and especially MRI in the presumptive diagnosis.

Intra-hepatic cholangiojejunostomy (group I patients) and simple trans-tumoral intubation (group II patients) were retrospectively compared in a series of 44 patients with primary carcinoma of the hepatic duct junction. Hospital mortality was 30% in the 13 group I patients and 9.5% in the 21 group II patients. Jaundice and pruritus were equally relieved in both groups. The mean survival time (hospital deaths excluded) was 16 months in group I and 12 months in group II patients. It is concluded that the decision as to which of these two palliative surgical procedures should be performed must rest on the degree of biliary duct distension as well as on the patient's age and general condition.

The authors report three cases of cystic tumors of the kidney: one benign papillary tumor and two renal cell carcinomas. Although the clinical features were atypical, the authors emphasize the role of computer tomography which make easier the diagnosis of these scarce tumors. When the diagnosis is doubtful a guided needle biopsy is recommended.

The authors study the incidence of urethral strictures after transvesical prostatectomy. A retrospective study of 90 patients and a prospective study of 78 patients found respectively 2% and 0% of urethral stenosis. The important data of this study is the duration of urethral catheter post operatively.

The authors report three cases of leiomyosarcomas of the small intestine and review the literature on this subject. Leiomyosarcomas of the small intestine are rare tumours, representing 0.2% of all malignant tumours of the gastrointestinal tract. These large, round, hypervascular tumours are derived from smooth muscle cells in the intestinal wall and often develop extra-luminally. The malignant nature is often difficult to confirm on the histological examination. The clinical signs often only appear when the tumour has reached a large volume. It is rare to make the diagnosis pre-operatively, despite the use of a number of investigations. Arteriography is the most reliable examination. Spread of the disease is essentially haematogenous. The malignant tumour invades adjacent organs, causes hepatic metastases and peritoneal seedlings and tends to recur locally. The treatment is essentially surgical and the prognosis varies according to the size of the tumour, its grade, its activity and its degree of extension. The 5-year survival of all forms of the disease varies between 20 and 50%, according to the series.

The authors report their experience with 37 patients treated by internal urethrotomy for urethral strictures. The results were appreciated on urethral calibration and flow rate after a median follow-up of 33,5 months and a minimal follow-up of one year. The rate of satisfying results was 78,3%. The authors emphasize the need of dilatations associated to low-doses of cortico-steroids in the post-operative period during the first three months, to improve the results.

We studied the results 42 liver resections performed for hepatocellular carcinoma. Thirty-three patients underwent major liver resections. Hepatocellular carcinomas were associated with cirrhosis in 30.9 p. 100 of cases. The overall operative mortality was 24.3 p. 100: 60 p. 100 in patients with cirrhosis who underwent major liver resections and 12.5 p. 100 in patients with cirrhosis undergoing limited resections. The overall 5-year survival rate was 14.8 p. 100; the 5-year survival rate in patients with hepatocellular carcinoma without cirrhosis was 20 p. 100 whereas no patient with associated cirrhosis of the liver survived at 3 years. We conclude that surgical resection of hepatocellular carcinoma must be performed whenever possible: a limited resection should be done if the tumor is small, especially in patients with cirrhosis; a major liver resection must be proposed when the tumor is large and if the remaining liver parenchyma is normal.

The authors study the incidence of urethral strictures after transurethral resection of prostate. A retrospective study of 135 patients and a prospective study of 187 patients found respectively 74% and 3.2% of urethral stenosis. Two important data are seen in this study, the duration of urethral catheter of 24 hours post operatively and the internal urethrotomy when they found a pathologic urethra pre operatively reduce the incidence of urethral strictures. With a normal urethra pre operatively and 24 hours of urethral catheter post operatively, any stenosis occurred, equally when an internal urethrotomy is done with a pathologic urethra pre operatively.

The review of the literature and our study of 15 tumors in bladder diverticula (IDT) show us that these tumors are rare and mainly observed in elderly adult males. Bleeding is the major symptom. Diagnosis is difficult and treatment is not well defined. Prognosis is good for low stage tumors and catastrophic in the short term for high stage tumors. Nearly half of IDT were primary tumors, and one third of them stay primary until death of the patients. Most of the high stage tumors contained a squamous cell differentiation and all the tumors with these features were deeply invasive. The bad prognosis is mainly related to the difficult and delayed diagnosis, with a long symptomatic period, regardless of treatment. This emphasizes the need for further investigations (biopsies, sonography, computer tomography) when the diagnosis is not evident. The treatment of these tumors depends on the general status of patients and the volume and stage of tumors. Low stage tumors (Ta) and diverticula could be treated either by transurethral resection or by open surgery with good results. In (T1) tumors, only open surgery is recommended to avoid loco-regional relapse. High stage tumors (greater than or equal to P T3) were treated by either TUR or open palliative surgery with the same bad prognosis. No radical treatment was indicated since patients have a bad performance status and most of the tumors extended beyond the diverticulum. Adjuvant treatments were not helpful. While preventive diverticulectomy is to be discussed case by case, we think that an important step in improving the prognosis of these tumors is to make the diagnosis at an earlier stage.
