[Leiomyoma of the urinary tract].

Leiomyomas of the urinary tract are benign and uncommon forms of tumor. In the present study, two cases have been described of leiomyomas situated in the bladder. Following this description, the pathological characteristics and the diagnostic and therapeutic aspects of these lesions have been examined. The clinical symptomatology depends on the tumor site, and this type of lesion is more frequently found in women.. Treatment mainly consists of endoscopic resection, but may involve cystectomy. The prognosis for patients with this type of tumor is invariably favorable.

[Giant scrotal condyloma acuminata: a case report].

In this study, the case has been reported of a scrotal tumor in a 50-year old male admitted with a large warty lesion at the base of the scrotum which resembled a giant condyloma accuminatum (Buschk-Lowenstein tumor). The HIV serology was negative, but the papillomavirus findings were positive. A complete resection of the tumor was performed. The histological findings confirmed the diagnosis of condyloma accuminatum without evidence of degenerative development into a squamous cell carcinoma. The clinical course was favorable, and no local recurrence was observed at 16 months follow-up. The problems that are frequently encountered in the diagnosis and therapy connected with this type of tumor have also been discussed.

[Primary adenocarcinoma of the bladder: report of a case].

The authors a case of primary adenocarcinoma of the bladder and studied the clinical, histological, therapeutical and evolutive aspects of this unusual tumor. It is a rare neoplasm that occurs for less than 2% of all bladder tumors and it is more prevalent in males between 50 and 60 years. The symptoms, exepting mucusuria, are non-specific, and hematuria is by far the most frequent presenting symptom. Different etiologies have been theorized, but this tumor is generally thought to arise through transitional epithelial metaplasia. The diagnosis is based on the pathologic anatomy examination. The treatment still not codified, but all of the authors advocate early aggressive surgery. The prognosis is poor.

[Giant hydronephrosis. Diagnostic aspect: report of a case].

In this study, we have reported an unusual case of giant hydronephrosis of the right kidney diagnosed as a result of pain, and upon palpation the detection of an abdominal mass. An ultrasound examination also indicated the possible presence of a large abdominal liquid mass. The hydatic serology was negative. A complementary CT scan and retroperitoneal approach confirmed the diagnosis of a right giant hydronephrosis with a liquid content of 8 liters, caused by stricture at the pyeloureteral junction with destruction of the kidney. The liquid was drained off. Based on the findings in this case, the pathogenesis, diagnosis and investigation of giant hydronephrosis have been discussed. In the event of giant hydronephrosis with total destruction of the kidney following an anomaly at the pyeloureteral junction, nephrectomy has to be performed. In the presence of a retroperitoneal liquid mass and in the absence of other pathological signs, the diagnosis of a possible giant hydronephrosis should be taken into consideration.

[Pyonephrosis: diagnosis and treatment: report of 14 cases].

Prior to the introduction of antibiotics, the treatment of pyelonephrosis frequently consisted of nephrectomy to remove the non-functional kidney, which was a potentially dangerous source of systemic infection. This approach was later modified as a result of the advances made in antibiotic therapy, and included vigorous antibiotic treatment and prompt drainage of the kidney. At present, percutaneous nephrostomy provides a means of draining off the pus and determining a possible residual renal function. In this study, 14 cases of pyonephrosis were observed over a 7-month period. Lumbar pain was noted in 70% of cases, painful lumbar contact in 5 cases and fever, shivering and pyuria in all cases. Cytobacteriological urine analysis showed the presence of Escherichia coli in 7 patients, Proteus in 4 patients, and in 3 cases abacterial leucocyturia; in 2 patients with only one functional kidney, renal insufficiency was observed. In all cases, the diagnosis was confirmed by ultrasonography. The main etiological factors were urinary lithiasis in 10 patients (71%), followed by uropathy of the pyeloureteral junction in 4 patients (29%). Treatment consisted of primary nephrectomy in 10 cases; in 3 cases, primary nephrostomy was performed with a positive outcome and recovery of renal function in 2 subjects; in one case of renal failure treated by nephrostomy followed by conservative surgery, the patient did not survive. In conclusion, nephrectomy is advocated as the treatment of choice in the case of a damaged kidney and a normal contralateral kidney. Conservative treatment should be envisaged particularly in the case of a single kidney, or if the patient's state of health is poor. The best treatment consists of the detection and cure of the lithiasis which is the main etiological factor in this pathology.

[Retroperitoneal sarcoma: report of 6 cases].

Retroperitoneal soft tissue sarcomas (RPS) are uncommon tumors. The diagnosis is frequently made later in the evolution of the disease due to the absence of specific symptomatology. Surgery with total resection of the tumor is the treatment of choice, but is only possible in 38 to 75% of cases. Six cases of RPS have been retrospectively reviewed; the mean time to diagnosis was 5 months; diagnosis was established via CT scan, which determined the retroperitoneal tumor location and its relationship to the neighboring organs. The most common symptoms were the presence of an abdominal mass and accompanying abdominal pain; signs of urinary and vascular compression were not found until later. Surgery with total resection was performed in 4 cases, and with partial resection in 2 cases. The histological findings were as follows: 3 liposarcomas, 2 rhabdomyosarcomas, and 1 fibrosarcoma. Tumor recurrence developed in 2 cases (liposarcomas), necessitating further surgery and complete resection. Two patients were lost to follow-up. RPS are characterized by locoregional relapse and metastases. Disease outcome depends on the histological type, tumor grade, and on the possibility of carrying out complete resection.

[Stab wound to the left solitary kidney: report of a case].

A forty-four-years old man with a left solitary kidney presented a stab wound in the left lumbar region. Upon admission, the patient was hemodynamically stable, the abdominal ultrasonography showed a small perirenal hematoma and the intravenous pyelography was normal. Two days later, he had no hematuria and was discharged from the hospital, with a computed tomography scan control two weeks later. Unfortunately, seven days later, the patient was admitted to emergency for left lumbar pain, a 40 degrees C fever and pyuria. The creatinine level was 72 ng/mL, and the computed tomography scan showed a large urohematoma. The patient was operated and required partial upper polar nephrectomy for distorted upper pole with infected hematoma. A large hematoma was removed and a nephrostomy tube was introduced. The renal function returned to normal six days postoperatively and the nephrostomy tube was removed after nephrostogram at 12 days. Concerning this uncommon case, we emphasize the advantage of the computed tomography scan and the necessity of emergency management in a patient with solitary traumatic kidney.

[Bilateral renal angiomyolipoma associated with tuberous sclerosis: report of a case].

The authors report a case of bilateral renal angiomyolipoma, associated with tuberous sclerosis revealed by abdominal pains, in a 30-year-old man. The diagnosis, suspected by the clinic and ultrasonography, is affirmed by CT scan. In light of this case, the authors review the features of this disease, the ambiguous character of angiomyolipoma, the prognosis and choice of management. Several elements incited us to adopt therapeutic abstention with regular monitoring of the patient for this begin tumor with slow evolution.

[Infrared spectrometry and urolithiasis. Report of 80 cases].

Urolithiasis is a frequent disorder that is characterized by its recurrence following treatment and which can affect between 3-20% of the population, with an incidence that differs from country to country. The aim of the present study was to determine the composition of the calculi, and the remain characteristics of this pathology in Morocco. A series of 80 calculi was therefore analyzed by Fourier transform infrared spectroscopy. The findings showed that calcium monohydrate oxalate was the main lithiasic component, indicating that hyperoxaluria plays a major role in the formation of the calculi. The component identified were as follows: calcium oxalate (58.75%), calcium phosphate and magnesium phosphate (17.5%), uric acid (15%), and urate (8.75%). In 91.25% of cases, the calculi were of mixed composition. Regular patient follow-up is advocated and subjects should be informed of the risk factor involved, as urolithiasic recurrence was observed in 10% of the cases in this series.

[Bivalve anatrophic nephrolithotomy].

PURPOSE: In the era of lithotripsy, surgery gets a limited place in the management of renal stones. This study has for a goal to evaluate the practice, indications and results of anatrophic nephrolithotomy in the treatment of staghorn calculi. PATIENTS AND METHODS: Between 1998 and 1999, six patients, mean age 37 years, had complete staghorn calculi treated by anatrophic nephrolithotomy, and two patients had a bilateral lithiasis. After lombar incision, the kidney was incised on the convexity after pedicular control. In this way, we have extracted all lithiases. The nephrorrhaphy permits hemostasis and parenchymal reparation. A ureteral stent was placed. RESULTS: The operatory follow-up was simple; hemostasis was controlled by fast extraction of the lithiasis and nephrorrhaphy. The operating time was 70 minutes (40-110). The stone free rate was 100% without alteration of renal function, patients with bilateral lithiasis have been operated twice time. CONCLUSION: The anatrophic nephrolithotomy is a safe technic without risk of haemorrhage or renal function alteration.

[Pheochromocytoma. Report of 10 cases].

We report 10 cases of adrenal pheochromocytoma seen over a period 15-years. A female predominance was noted (8 women/2 men). Patients were aged between 16-46 years with a mean of 34 years. Clinical manifestations consisted of hypertension observed in all cases, with vasomotor symptoms (90%). Time to consultation was prolonged (mean: 23 months). CT scan performed in 7 cases showed pheochromocytoma in all cases, located on the right side in 6 cases, while one pheochromocytoma was located in Zukerkandal organ. All patients were operated via anterior approach and adrenalectomy was performed. A favourable course was observed in 90% of cases with normalisation blood pressure. One death was noted. Histological examination showed no malignancy in all cases.

[Peritonitis caused by spontaneous rupture of pyonephrosis in pregnancy. Report of a case].

Peritonitis after spontaneous rupture of pyonephrosis into the peritoneal cavity is a rare complication, usually diagnosed intraoperatively. We report a case of a woman presenting with left lumbar pain and fever during pregnancy. On admission, ultrasonography showed a pregnancy with fetal activity for 16 weeks, and pyonephrosis in the left kidney, but on a normal right kidney. After antibiotic therapy and upper urinary, tract stenting renal drainage revealed purulent urine, fever persisted with acute abdomen. Clinical and radiological assessment showed features of acute peritonitis with pyonephrosis. Treatment consisted of laparotomy with nephrectomy and abdominal lavage and drainage. The postoperative complication was septic shock requiring resuscitation and artificial ventilation and prolonged convalescence.

[Bladder tumors in young patients].

Bladder tumours classically affect the elderly, but can also occur in young adults. The authors studied the prognosis of these tumours in patients under the age of 40. In their experience, these tumours represent 3.27% of all bladder tumours. 26 patients with a mean age of 34 years (20-40 years), 8 under the age of 30, were studied. There was a marked male predominance (23 males, 3 females). The tumour was a transitional cell carcinoma in 25 cases and a squamous cell carcinoma in 1 case. It was superficial in 11 cases and invasive in 15 cases. Transurethral resection and cystectomy were performed in 9 cases of superficial tumours and 11 cases of invasive tumours, respectively. In the group of superficial tumours, a favourable course was observed in 7 cases, with 3 cases of recurrence and 1 case of progression. In the group of invasive tumours, a favourable course was observed in 6 cases, recurrence was observed in 2 cases and 5 patients died. Superficial tumours therefore have a better prognosis in subjects under the age of 30. Invasive tumours are more frequent and often advanced, suggesting a marked potential for progression. Their prognosis depends on tumour stage, and is not correlated with age.

[Bolande tumor in adults: apropos of a case].

Bolande's tumour or congenital mesoblastic nephroma is essentially a tumour of infants under the age of one year and is rare in adults, in whom only 10 cases have been described. The authors report the 11th case in a 30-year-old woman, in whom a right renal tumour was discovered during ultrasonography at 34 weeks of pregnancy. Radical nephrectomy was performed after delivery, with a favourable course at 3 years, with no recurrence or metastasis. The aetiopathogenic and diagnostic aspects are discussed, with emphasis on the possibility of a hormonal inducing factor in the histogenesis of this tumour.

[Primary urothelial carcinoma of the urethra. Apropos of a case].

We report an unusual case of primary transitional cell carcinoma in the bulbar urethra. The patient was a 52-year-old man with a history of sexually transmitted disease. The clinical presentation was bladder retention with urethral bleeding. Radiological examination and cystoscopy showed a bulbar urethral tumor. The pathological diagnosis was Grade III transitional cell carcinoma with invasion of the corpus spongiosum (T2). Partial resection of the urethra was performed and the patient has been without evidence of disease for two years.
