[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.

[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.

[Diagnostic and therapeutic problems of an atypical cyst of the kidney].

Atypical renal cyst raises diagnostic and therapeutic problems. The authors report a case of atypical renal cyst which raised numerous diagnostic and therapeutic problems. The authors discuss theses problems in the light of this case. A farmer consulted for right lumbar pain without hematuria and hydaturia. Hydatic serology was negative. Ultrasonography and CT scan showed atypical cyst in favour of hydatic cyst. Surgical investigations showed a necrotico-hemorragic cyst, and cystectomy was performed. Histological examination revealed a chronic inflammatory process without malignancy. One year after the operation, clinical and radiological examination were normal.

[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.

[Perineal recurrence of resected penile cancer. A case report].

The authors report an unusual case of perineal recurrence of squamous carcinoma of the penis in a 50-year-old, white man, circumcised during infancy and operated 5 years previously for stage T3N0M0 squamous carcinoma of the penis by total amputation of the penis. Clinical examination revealed a very large, infected perineal tumour associated with bilateral inguinal lymphadenopathy. This stage T4N2M0 tumour was treated palliatively by cystostomy, emasculation with perineal tumour reduction and antibiotics. The patient became afebrile and the infection resolved and was referred to the radiotherapy department for further treatment.

[Prostatic abscesses. A review].

We review the literature to the diagnosis and therapeutic aspect of prostatic abscess. The prostatic abscess having become an uncommon disease. The diagnosis of prostatic abscess has been nearly made by transrectal ultrasound and computed tomography scan. The best diagnostic method is considered to be the transrectal ultrasound. The choice therapy was intravenous antibiotic, and drainage by ultrasound guided transperineal percutaneous puncture.

[Retroperitoneal ganglioneuroma. Apropos of a case].

Ganglioneuroma is a rare tumour in adults. We report the case of a 26-year-old woman admitted in our department with right renal colic. Ultrasonography and computed tomography showed a heterogeneous retroperitoneal mass measuring 8 x 7 cm in diameter and displacing the ureteropelvic junction and right kidney anteriorly and laterally. The preoperative diagnosis was retroperitoneal tumour. Surgical exploration revealed a totally resectable retroperitoneal tumour with a histological diagnosis of ganglioneuroma.

[Appendiceal mucocele disclosed by a psoas tumor. Apropos of a case].

Mucocele of the appendix is a rare lesion. Rupture of appendicular mucocele into the psoas is uncommon. We report a case of a 77-year-old man, with psoas tumor on abdominopelvic ultrasonography and computed tomography. The preoperative diagnosis was type III hydatid cyst of the psoas, psoas tumor or retroperitoneal mass. Surgical exploration revealed an appendicular mucocele ruptured into the psoas. Appendicectomy was performed with an uneventful postoperative course after 3 years. The authors discuss the diagnostic and therapeutic problems raised by this rare lesion.

[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.

[Torsion of an undescended testis. Apropos of a case].

The authors report an uncommon case of torsion of an inguinal undescended testis occurring in a 15-year-old child. He consulted seven days later for isolated left inguinal pain. Physical examination showed a left inguinal mass, and only the right testis was palpable within the scrotum. Sonography revealed left inguinal mass with echogenic and heterogeneous contents in keeping with undescended testis. The diagnoses of testis tumor or testis torsion were suggested. Surgical exploration revealed a mass suggesting a testis tumor. Orchidectomy was performed. Histological examination showed that the mass corresponded to a necrotic ischemic testis without tumor cells. In the light of this case, the authors analyse the diagnostic aspects and management of torsion of an undescended testis.

[Tumors of the bladder in women. Epidemiologic and therapeutic aspects. Apropos of 40 cases].

Bladder tumours in women. Epidemiological aspects and treatments, based on a series of 48 cases. Bladder tumours are more frequent in men than in women, in whom they present certain epidemiological, clinical and therapeutic characteristics. The authors report a retrospective study of 48 cases of bladder tumour in women, observed in the urology department over a 20-year period. These tumours represented 4.2% of all bladder tumours. The patients had a mean age of 59 years (range: 29 to 77). Only one patient was a smoker (2%). Haematuria was present in 93% of cases, and signs of bladder irritation were present in 60% of cases. All tumours were transitional cell carcinomas. The tumour was classified as stage 0 in 10 cases (20.9%), stage A in 15 patients (31.2%), stage B in 22 patients (45.8%) and stage C in 1 case (2.1%); no patients (0%) were classified as stage D. Our therapeutic protocol was established as a function of the stage of tumour invasion. For example, superficial tumours were treated conservatively by transurethral resection, either alone or combined with intravesical instillation. Radical surgery was performed whenever possible for invasive tumours. External urinary diversion was performed in 11 cases, ureterosigmoidostomy in 3 cases and enterocystoplasty in 5 cases. The clinical course of the 15 superficial tumours was marked by recurrence in 5 cases, while that of the 23 invasive tumours was marked by local recurrence (3 cases), renal failure (1 case) and 3 deaths.

[Epidemiology of urinary lithiasis].

The objective of this study was to analyse the epidemiological profile of urinary stones based on one thousand cases observed in our institution over a 10-year period. The mean age of the patients was 45 years and two-thirds of patients were males. The kidney was the commonest site of stones, in 57.8% of cases. The stone was radiopaque in 86.4% of cases and was a staghorn calculus in 12.2% of cases. An associated renal malformation was observed in 10.4% of cases. Urinary stones is therefore a common disease, essentially observed in a young population and characterized by recurrence. It therefore constitutes a public health problem and prevention consists of detecting recurrences and treating stone-inducing factors.

[Foreign bodies of the bladder and urethra. Apropos of 2 cases].

The bladder and urethra can be the site of various types of foreign bodies. The authors report two cases of low urinary tract foreign bodies. The first case concerned a young man with psychiatric disorders who introduced a condom into his bladder and the second case was an elderly patient with a history of self-dilation who introduced a safety pin into his urethra. In the light of these two cases, the authors review the diagnostic features and management of bladder and urethral foreign bodies.

[Hydatid cyst of the psoas muscle. Apropos of a case].

The authors report a rare case of hydatid cyst of the psoas muscle in a 28-year-old woman, operated for vertebrospinal hydatid cyst. The patient presented with a left iliac fossa mass. Ultrasonography and computed tomography contributed to the preoperative diagnosis, despite negative hydatid serology. A retroperitoneal approach by left lumbotomy with partial pericystectomy was performed. In the light of this case, the authors discuss the diagnostic and therapeutic problems raised by hydatid cyst of the psoas muscle.

[Primary pyogenic abscess of the psoas muscle. Apropos of 5 cases].

The authors discuss the diagnostic and therapeutic aspects of primary pyogenic abscess of the psoas muscle based on a series of 5 cases. Five patients between the ages of 15 and 64 years (mean: 38.2 years) were admitted to the urology department between January 1994 and December 1996 with fever, abdominal pain and low back pain, and psoitis in 1 case. The mean delay to consultation was 42 days. Clinical examination revealed a painful mass in the lumbar region and flank in 5 cases. Leukocytosis was detected in 5 patients. Radiological examination demonstrated loss of the lateral border of the psoas in 4 cases. Ultrasonography showed an enlarged psoas muscle in every case with a hypoechoic mass in 2 cases and a heterogeneous mass in the other 3 cases. Computed tomography, performed in 2 patients, confirmed the ultrasound findings in 1 case and excluded the diagnosis of type IV hydatid cyst of the psoas muscle in the other patient. The abscess was evacuated by percutaneous drain in 1 patient requiring a second percutaneous drainage for reconstitution of the abscess. Surgical drainage was performed immediately in 3 patients and after failure of antibiotic treatment in 1 patient. The hospital stay did not exceed 7 days after surgical drainage, but was 25 days after the first percutaneous drainage and 20 days after the second percutaneous drainage. The authors emphasize the multiple advantages and efficacy of surgical drainage of psoas abscess.

Primary osteosarcoma of the cervical spine: one case.

The authors report the case of a 31-year old woman who was operated upon for cervical bone tumour. The pathological study showed that it was a primary, highly differentiated osteosarcoma. The clinical picture was limited to a spinal cord compression syndrome without signs of inflammation. Radiological findings were non-specific. Treatment consisted of laminectomy, radiotherapy and chemotherapy. The course of the disease was marked by stabilization, then rapid aggravation 2 years after the operation. A review of the literature highlighted the rarity and relatively slow progression of primary osteosarcomas of the spine.
