Transperitoneal Laparoscopic Pyelopyelostomy for Retrocaval Ureter without Excision of the Retrocaval Segment: Experience on Three Cases.

Introduction. Retrocaval ureter is a rare congenital anomaly. Open surgery was the classic treatment for this condition. Laparoscopy is currently an admitted procedure to treat many urological diseases. The objective of our study is to present our experience and discuss the safety and the feasibility of transperitoneal laparoscopic pyelopyelostomy for treatment of retrocaval ureter (RCU). Materials and Methods. Three symptomatic patients underwent laparoscopic repair for RCU in our department. The diagnosis was suspected on the computed tomography scan (CT) and confirmed on ascending pyelography. After placement of a JJ stent, and, using the transperitoneal approach, the retro peritoneum was exposed; the ureter was identified in both sides of the vena cava. The retrocaval segment was entirely mobilized and pulled from behind of the vena cava after section of renal pelvis. A pyelopyelostomy was done in a normal anatomic position. Results. All operations were achieved laparoscopically without conversion to open surgery. The mean operative time was 140 minutes (110-190). No intraoperative complication occurred. Blood loss was less than 50 mL in all patients. The mean hospital stay was 5 days (4-6 days). All patients were symptom-free after surgery and had reduction of hydronephrosis in control imagery. Conclusion. Laparoscopy seems safe, feasible, and reproducible in managing retrocaval ureter.

Percutaneous endoscopic nephropexy with a percutaneous suture passed through the kidney.

OBJECTIVES: To report a technique of percutaneous endoscopic nephropexy, using a polyglactin suture passed through the kidney, in patients with nephroptosis. PATIENTS AND METHODS: Four women presenting with symptomatic right nephroptosis underwent a percutaneous endoscopic nephropexy. An upper-pole calyx was accessed percutaneously and a 24-F working sheath was placed. Another needle access was made through a lower-pole calyx and a #2 polyglactin suture was passed into the renal pelvis. It was then pulled out through the upper-pole tract using the nephroscope. A retroperitoneoscopy was performed and the tip of the nephroscope was used to cause nephrolysis. After inserting the nephrostomy tube the polyglactin suture was passed into the subcutaneous tissue and then tied without too much tension, to avoid cutting the parenchyma. RESULTS: The operative duration was 33 min and the hospital stay after surgery was 3.5 days. The nephrostomy catheter was removed 5 days after surgery. There were no complications, especially no haemorrhagic, infectious, lithiasic or thoracic complications. The four patients were relieved of their initial symptoms, with a mean follow-up of 28 months. Ultrasonography and/or intravenous urography showed the kidney at a higher location with the patient standing. CONCLUSIONS: This technique combines the nephrostomy tract used in percutaneous techniques with the suture and nephrolysis used in laparoscopic techniques. Moreover, this procedure seems to be safe, with satisfactory anatomical and clinical results and a lower morbidity. However, a larger series will be necessary to establish its long-term morbidity and success rate.

[Pathological pelvic kidney. Apropos of 11 cases]. / Le rein pelvien pathologique. A propos de 11 cas.

The diseases ectopic kidney is a rare malformation. It can be associated with other urological or nonurological malformation. We report 11 cases observed between 1980 and 1998. They were five females and six males with a mean age of 28 years. The clinical symptomatology was dominated by pain and urinary symptoms. Diagnosis was based on the IVP data and ultrasonography. Renal stone and hynronephrosis were each associated in five cases and one patient had renal stone associated with hydronephrosis. The treatment consisted on a iliopelvic approach and extraction of the stone and or pyeloplasty. In three cases a nephrectomy was realised for muet kidney or pyonephrosis. The outcome was good in ten cases and one patient had a pyelo-ureteral secondary stenosis managed by endoscopy.

[Detrusor-sphincter dyssynergia: four case reports and literature review]. / La dyssynergie vésicosphinctérienne: présentation de quatre cas et revue de la littérature.

UNLABELLED: Detrusor-sphincter dyssynergia is responsible for major impairment and is factor for social and professional activity repercussions. METHODS: We have studied the clinical and urodynamic finding in four patients (two men and two women) with detrusor-sphincter dyssynergia. Mean age is 36 years (26-44 years). Dyssynergia was secondary to tuberculosis meningitis in one case, surgery for rectal adenocarcinoma in one case, tight vertebral canal in one case and in one case the cause is indeterminate. The detrusor-sphincter dyssynergia were treated by autocatheterism in two cases, antibiotherapy antituberculosis associated with an anticholinergic drugs in one case and by alpha-blockers agent in another. RESULTS: Quasi-complete salvage of the motor deficit and the dysfonctional voiding in a patient treated by antibiotherapy antituberculosis associated with an anticholinergic drugs. As well, maid evolution in patient treated by alpha-blockers agent and who practice self catheterization. CONCLUSION: Optimal treatment is unknown, and the existence of several cures indicated the limit of all therapeutic methods.

Adrenal myelolipoma. A case report.

We report a new case in a 56 years old patient who manifested right side's pains. The abdominal CT scan showed a tumor of the right adrenal gland with fat density (size: 8 x 6 x 6 cm). This tumor was removed surgically (weight: 300 g). The histological finding revealed a proliferation of adipocyts and myeloid tissue which contains megakaryocytes, erythroid cells and lymphocyts. The outcome is good after three years of surgery. The surgical treatment becomes necessary when the tumor's size increases or it becomes symptomatic.

[Subcapsular spontaneous hematoma of the kidney of non-tumor origin (report of 5 cases)]. / Hématome spontané sous capsulaire du rein d'origine non tumorale (à propos de cinq cas).

Spontaneous subcapsular haematoma (SCH) of the kidney is a rare condition, secondary to kidney tumours in more than 50% of cases. Nephrectomy is justified in the presence of tumour or uncontrolled haemorrhage. When the aetiology cannot be determined, thin-slice CT follow-up of the patient's kidney can be performed. The authors report 5 cases of SCH of the kidney. A retropelvic aneurysm was responsible for the haematoma in one case; polyarteritis nodosa was the cause of bleeding in another case and the aetiology could not be determined in two cases. All patients were managed surgically. Nephrectomy was performed in 3 cases and simple evacuation of the haematoma was performed in 2 cases.
