Percutaneous extra-anatomic nephrovesical diversion: preliminary report.

We propose a new approach to total ureteric replacement based on the use of a new spiraled composite tube. This tube is inserted percutaneously into the renal pelvis, then tracked subcutaneously and introduced into the bladder via a short incision. The tube is maintained in place by anchoring its spirals along the subcutaneous tract, and only the two silicone extremities are in continuous contact with the urine. We have used this technique for total replacement of the ureter in one renal transplant patient with a follow-up of 8 months and no complication. A longer follow-up is obviously necessary, but this new, minimally invasive approach, using a newly designed tube, would appear to give a new lease of life to an old, abandoned principle.

[Interstitial cystitis].

Interstitial cystitis, described for many years, remains a mystery for several reasons. Although the clinical and therapeutic understanding of this disease have improved, the histological features are non-specific and the pathogenesis is still unclear. The aim of this article is to briefly review the current state of knowledge and to remind the reader that this disease must not be underestimated or ignored.

[The treatment of metastasized kidney cancer. Current data and perspectives].

Metastatic renal cancer has a poor prognosis because of the limited impact of traditional treatment modalities on this tumour. The few long-term survivals obtained after isolated surgical resection of the primary tumour or its metastases can be attributed to the occasionally unpredictable natural history of this tumour and isolated surgical resection generally does not appear to improve the survival of these patients. Among non-surgical treatments, radiotherapy is purely palliative and hormone therapy has been shown to be ineffective. New therapeutic approaches have been recently developed, suggesting a possible improvement in the prognosis of metastatic renal cancer. A better understanding of the mechanisms of chemoresistance of renal cancer should lead, in the near future, to the use of drugs capable of increasing the efficacy of cytotoxic chemotherapy in this tumour. The results obtained with new forms of immunotherapy open up prospects for combined immunosurgical modalities.

[Should fragments of stone expelled after extracorporeal lithotripsy always be analyzed?].

The morphological and constitutional analysis of renal stone fragments expelled after extracorporeal shock wave lithotripsy enables the structure and morphological type of stones to be reconstructed in 92.8 per cent of the cases as regards surface and section and in 74.5 per cent of the cases down to the core. A study of the molecular and crystalline composition of such fragments demonstrated the preponderance of whewellite in both sexes (men 85.4 per cent; women 72.4 per cent). The frequency of weddellite was 1.6 times higher in men (73.8 per cent) than in women (44.8 per cent), and the frequencies of struvite and ammonium urate were 2.8 and 2.6 times respectively higher in women than in men, despite a significant fall in frequency as compared to a previous series. Correlations between morphological type of stone and biochemical data (when available) could be established in 84 per cent of the cases. This made it possible to initiate treatments aimed at preventing recurrences, the cost of these treatments in the long term being lower than that of the curative urological treatments, including extracorporeal shock wave lithotripsy.

[Leiomyoma of the urinary excretory tract].

Four cases of leiomyoma of the urinary tract are presented: 3 locations in the bladder and one location in the ureter. Leiomyomas of the urinary tract are rare. These benign mesothelial tumors require conservative resection. Small lesions can be managed with endoscopic techniques.

[Unilateral bladder neck incision: endoscopic treatment of bladder neck obstruction. Results in 100 patients].

Endoscopic diathermy unilateral incision of the bladder neck was carried out in 100 consecutive male patients. This procedure was performed for bladder neck obstruction and small benign prostate. The operative details of this technique are given. Follow-up after 2 months revealed excellent symptomatic and urodynamic results. Morbidity was low. Results remain stable after 13 +/- 9 months. One patient needed a transurethral resection of the prostate. Retrograde ejaculation occurred in 5% of the patients. Unilateral bladder neck incision is a simple procedure safe, and easy to learn, with a low risk of retrograde ejaculation. It is the operation of choice for small benign prostate, bladder neck obstruction and young patients.

[Endoscopic nephrotomy].

A procedure of small endoscopic nephrolithotomy during open surgery for staghorn calculi is described. This procedure is based on the principle of percutaneous nephrolithotomy. Same instruments are used. These endoscopic nephrostomies are less traumatic.

[Vesico-urethral fibroscopy. Reflections after 4 years' practice].

The visualisation of the lower urinary tract by the mean of a fiberscope makes an advance when compared to rigid endoscopy mainly in male patient. Technical features of the fiberscopes suitable for urology thus basic technique of the examination are described. Main advantages are painfree and total visual scanning of the mucosa. Disadvantages are very low.

[Percutaneous nephrolithotomy: perspectives for the future. Analysis of 250 cases in 3 years' experience].

The authors report their experience of percutaneous nephrolithotomy over a period of three years. The analysis of the first 250 cases performed reveals a low morbidity, with serious complications in 1% of cases, and an acceptable complete success rate of 83%. The indications for percutaneous nephrolithotomy have been modified since the opening of an extracorporeal lithotripsy unit. The choice between the two techniques depends on their efficacy and their expected morbidity based on four criteria: the volume, chemical composition and site of the stone and the morphology of the upper urinary tract. Percutaneous nephrolithotomy is the treatment of choice for large stones (greater than 2.5 cm), hard stones or those formed proximally to a stenotic lesion of the urinary tract, which can then be dilated at the same procedure. A combination of the two methods is sometimes uses to treat staghorn calculi with a success rate of 80%. On the other hand, very large staghorn calculi with caliceal branches are best treated by open surgery.

[Papillary "endometrial" adenocarcinoma of the bladder neck. Light and electron microscopy and immunohistochemistry].

A case of papillary adenocarcinoma, developed on the urinary bladder neck is reported. This tumor is histologically identical to so called endometrial carcinoma of the prostate. Immunohistochemistry showed acid phosphatases and prostatic specific antigen (PSA) positive cells. Electron microscopy disclosed secretory vacuoles consistent with a prostatic origin. The histogenesis of endometrial carcinoma is briefly discussed likewise the precise site of origin of the reported case.

[Reabsorption of the irrigation solute during percutaneous nephrolithotomy].

The publication of several accidents, possibly due to the reabsorption of irrigation solutions in the course of percutaneous nephrolithotomy, prompted the authors to quantify the amounts of glycine (1.50 per cent glycocol) reabsorbed in these operations, and to determine the metabolic consequences. In a prospective study of twelve patients subjected to fourteen percutaneous nephrolithotomies, the hemodilution parameters (natremia, protidemia, hematocrit and osmolality) and the amino acid content of the plasma were measured preoperatively, at operation, and immediately postoperatively. The study indicates that there is a hemodilution and reabsorption of irrigation solute comparable to that observed in transurethral resections of the prostate. The resultant hyperglycinemia probably explains the significant increase in ammonemia noted in all the patients. One theory is that hepatocellular insufficiency may increase this ammonemia. This might suggest the advisability of using saline solution, at least in these patients (that is, of course, in the absence of electrical lithotrity).

[Percutaneous renal surgery. Analysis of 100 cases of percutaneous nephrolithotomy].

The authors review a series of 100 consecutive patients treated by elective percutaneous nephrolithotomy. The success rate was 83%, and the complication rate, under 2%. For these reasons, percutaneous nephrolithotomy is becoming an established procedure for the surgical management of kidney stones. After an initial phase, the one-stage manipulation was performed with a mean hospital stay of 4 days in 70% of cases.

Nutrition and immunity after peritoneovenous drainage of intractable ascites in cirrhotic patients.

Severe malnutrition and related impaired cell-mediated immunity are commonly found in cirrhotic patients with intractable ascites and may be responsible for the poor prognosis of these patients. The effects of LeVeen peritoneovenous shunting of ascites on protein reserves and cell-mediated immunity were studied in 31 cirrhotic patients with intractable ascites over a period of 1 year following operation. Arm-muscle circumference, serum albumin, and transferrin levels markedly increased and became close to the normal values. In the same period, delayed hypersensitivity improved. Although the lymphocyte count and the absolute T cell concentration in peripheral blood remained low after peritoneovenous shunting, the in vitro lymphoblastic transformation in response to phytohemagglutinin was augmented. An increased capacity to eat normal meals and the resumption of a good appetite due to the discontinuation of a salt-restricted diet seemed to be the most important factors in the dramatic improvement in the nutritional status of these patients. Restriction from heavy alcohol use may have also contributed, although the patients had already stopped drinking for several months before operation. Improvement in cell-mediated immunity might have been secondary to the increase in protein reserves.
