[Pyelo-ureteral syndrome: the impact of endo-urological techniques].

The present article reports our experience with endopyelotomy, a technique we have performed at our hospital since 1985. Sixty-two patients comprise this series. Of these, 57 were evaluated more than 6 months after treatment (65 cases of ureteropelvic junction syndrome (UPJS); 26 were primary UPJS (success rate 81%) and 39 secondary UPJS (success rate 84.5%). The complication rate was low. Patients in whom endoscopic treatment had failed were submitted to open surgery with no particular difficulty. A comprehensive review of the literature highlighting the indications, techniques and results achieved with this procedure is performed.

[Long-term results of endourological treatment with and without ESWL in cystine lithiasis].

From 1984 to 1989, 15 patients with cystine calculi were treated by endourologic procedures and/or extracorporeal shock wave lithotripsy (ESWL). During this period the patients required 38 hospitalizations, a total of 74 calculi were treated localized to 61 sites: pelvic 21, caliceal 13 and 27 were multiple. The diagnosis was confirmed by a 24 hour cystinuria (3.595 muMol/24 h. average) and analysis of the stone fragments. Stone disruption was achieved in 17 of 38 cases (44.7%). ESWL as monotherapy was utilized in calculi less than 15-20 mm. in diameter; complete removal was achieved in of 18 cases. Percutaneous surgery (PC) was used alone or in combination with ESWL for large calculi or when ESWL failed to achieve stone fragmentation. Complete stones removal was achieved in 5 of 9 cases using PC as monotherapy and in 5 of 10 in combination with ESWL. There were 23 recurrences during this period; 13 patients with residual stone fragments and 10 patients that were stone-free. The present study reports our experience in the treatment of cystine calculi by PC and/or ESWL and the long-term results achieved with the respective treatment modalities.

[Percutaneous resection of benign renal cysts].

Six patients carrying bulky renal cysts located in the kidney lower pole were treated by percutaneous resection of the cystic wall. No complications were observed during the peri and postoperational period. In all cases disappearance of symptoms was observed, and the total success rate (absence of residual cavity) recorded was 4/6, two cases presenting persistence of a small residual cavity which originated one case of relapse. The paper presents the technique used, and the indications and possible therapeutic actions for the treatment of simple kidney cysts are discussed.

[Endourologic treatment of tumors and pseudotumors of the upper excretory system].

Thirteen patients with a benign tumor or pseudotumor of the upper urinary tract underwent endourological treatment on 17 occasions. These patients were divided into two groups according to the anatomopathological findings. Five patients comprised group I. Mean patient age, 57.3 years. These patients had a tumor in the excretory cavity. Endoscopic work up revealed 3 papillary necroses, 1 inflammatory polyp, 1 Von Brun islet. One ureterorenoscopy (biopsy + laser) and four percutaneous (tumor resection) procedures were performed. Eight patients comprised group II. Mean patient age, 59 years. Six patients had pyelocaliceal tumors and two patients had ureteric tumors. Histologic analyses revealed a noninvasive low grade tumor on six occasions and two fibroepithelial polyps. Two ureteric tumors and 1 pelvic tumor were treated by retrograde ureterorenoscopy (2 resections and 1 Nd/Yag laser photocoagulation). Five patients were treated percutaneously (resection alone or combined with Nd/Yag laser). Four patients received local chemotherapy. Patient follow-up ranged from 1 to 3 years. Tumor recurrence was observed in 3 patients treated by percutaneous resection.

[Renal autotransplantation in the treatment of renovascular hypertension].

Surgery plays an important role in the treatment of renovascular Hypertension (RVHT). 123 RVHT carrier patients were treated by means of 101 single autotransplants (11 double autotransplants) and 34 autotransplants preceded by extracorporeal replacement of the branches of the renal artery (1 bilateral case). Taken all round, the patients improved either totally or partly (93.5%). In lesions involving multiple branches of the renal artery, replacement of these by a hypogastric autologous arterial transplant is regularly the only technique possible to save the kidney.

[Percutaneous endopyelotomy].

Endourologic treatment of the ureteropelvic junction syndrome was performed 48 times in 45 patients (1 was bilateral, and 2 required repeat treatment) via a percutaneous incision of the stenosis, and placement of a modelling double-J catheter, which was left indwelling for 4 to 6 weeks. Evaluation of the results between 6 months and 3 years revealed a success rate of 81.5% for secondary stenosis and 73.7% for congenital stenosis. If the foregoing technique fails, pyeloplasty can be performed without difficulty.
