Surgical care, morbidity, mortality and follow-up after nephrectomy for renal cancer with extension of tumor thrombus into the inferior vena cava: retrospective study since 1990s.

OBJECTIVES: The aim of our survey was to evaluate surgical care, morbidity, mortality and follow-up of patients who had undergone surgical exeresis of a renal cancer with extension of tumor thrombus into the inferior vena cava. PATIENTS AND METHODS: Between June 1991 and March 2003, 40 (5.4%) patients were operated on for an enlarged nephrectomy with thrombectomy. The upper limit of the tumor thrombus was below the sus-hepatic veins in 21 (52.5%) patients and above the sus-hepatic veins in 19 (47.5%) patients with six (15%) located in the right atrium. RESULTS: Cardiopulmonary bypass (CPB) was used for 12 patients (30%). A per-operative embolism was noted for three (7.5%) patients: two cases of cruoric embolism and one case of gaseous embolism, systematically occurring in patients operated on without CPB. Early mortality was 7.5% (three patients) attributable to hemorrhagic complications. Overall survival at 2 and 5 years was 45.2% and 38.7%, respectively. Disease-free survival at 2 and 5 years was 28.3% and 8.9% respectively. Only the pN stage had a statistically significant prognosis value for overall survival but not for disease-free survival. At the end of the study, only one (2.5%) patient could be considered free of the disease with sufficient follow-up after the surgery. CONCLUSION: Patients with renal cancer and tumor extension in the inferior vena cava need multidisciplinary cooperation to adapt a good surgical strategy, particularly with the use of CPB. However, the rate of patients free of disease after such surgery was low.

[Morbidity and mortality of renal cancer with inferior vena cava extention according to various types of surgical management].

OBJECTIVE: The objective of this study was to evaluate the mortality and morbidity of patients operated for renal cancer with inferior vena cava extension according to the surgical management and the upper limit of the tumour thrombus. underwent radical nephrectomy with resection of neoplastic venous thrombus extending into the inferior vena cava. The upper limit of the tumour thrombus was below the hepatic veins in 21 cases (52.5%) and above the hepatic veins in 19 cases (47.50%) with invasion of the right atrium in 6 cases (150). RESULTS: Cardiopulmonary bypass (CPB) was used in 12 patients (30%). The transfusion rate was 87.5%. In the group of 19 patients with thrombus extending above the hepatic veins, the transfusion rate was lower in patients operated by CPB (p=0.008). Intraoperative embolism occurred in 3 patients (7.5%): 2 cases of thrombotic embolism and 1 case of gas embolism, always in patients operated without CPB. The early mortality was 7.5% from haemorrhagic complications. The early morbidity was 47.5%. No significant difference was observed between groups of patients operated with or without CPB in terms of morbidity (p=0.836) or mortality (p=0.896). CONCLUSION: The management of patients with renal cancer and inferior vena cava extension is complicated and requires a multidisciplinary approach. Patients operated under CPB for tumours extending above the hepatic veins have a lower transfusion rate and a lower embolic complication rate with no increase of mortality and morbidity.

[Oncological results of renal cancer with inferior vena cava thrombosis after nephrectomy].

OBJECTIVE: The objective of this study was to evaluate survival and risk of recurrence in patients undergoing nephrectomy with resection of inferior vena cava tumour thrombus in our department. MATERIAL AND METHODS: From June 1991 to March 2003, 40 patients underwent radical nephrectomy with resection of inferior vena cava tumour thrombus. The upper limit of the tumour thrombus was below the hepatic veins in 21 cases (52.5%) and above the hepatic veins in 19 cases (47.5%), with thrombus in the right atrium in 6 cases (15%). Cardiopulmonary bypass (CPB) was used in 12 patients (30%) RESULTS: With a mean follow-up of 28.5 +/- 36.8 months (range: 0-150), 22 patients (55%) have died. The 2- and 5-year overall survival rates were 45.2% and 38. 7%, respectively. Local and/or metastatic recurrence was observed in 28 patients (70%) after a mean interval of 18 +/- 22.9 months (range: 1-104). Patients with tumour thrombus derived from the left kidney had a higher local recurrence rate than patients with thrombus derived from the right kidney (p = 0.0194). The 2- and 5-year recurrence-free survival rates were 28.3% and 8.9%, respectively. Only stage pN had a statistically significant prognostic value on overall survival, but not on recurrence-free survival. At the end of the study, only 1 patient (2.5%) can be considered to be cured with no disease progression with a sufficient follow-up (52 months) after nephrectomy. CONCLUSION: Nephrectomy with resection of tumour thrombus from the inferior vena cava provides a gain in terms of medium-term survival, but the majority of patients are not cured by this major surgery. Only lymph node status has a prognostic value.

[Complications of Bricker ileal conduit urinary diversion: analysis of a series of 246 patients].

OBJECTIVE: The objective of this retrospective study was to evaluate the mortality and early and late morbidities of Bricker ileal conduit urinary diversion. PATIENTS AND METHODS: Between January 1990 and December 2002, 246 Bricker ileal conduit urinary diversion was performed in our centre in 164 males (67%) and 82 females (33%) with a mean age of 64 years (range: 9 to 90 years). Bricker diversion was performed in 73.6% of cases for underlying tumour (prostate, bladder, cervical, colon cancer), and in 26.4% of cases for benign disease (neurogenic bladder radiation bladder bladder exstrophy, incrusting cystitis). Cystectomy was associated with Bricker diversion in 62.2% of cases. The mean follow-up was 24 months (range: 1 to 151 months). The following parameters were studied: mortality and early and late medical or surgical, urological and gastrointestinal complications. RESULTS: The postoperative mortality was 6.9% (17 deaths, 16 in patients in whom Bricker diversion was performed for cancer). The early morbidity was marked by gastrointestinal complications (ileus, fistula, evisceration) in 46 cases (1.7%), 25 of which required re-operation. A medical complication was observed in 41 patients (16.7% of the series), responsible for 60% of the postoperative mortality (10 of the 17 deaths). A urinary fistula was observed in 7 patients (2.8%). The late morbidity consisted of parietal complications (incisional hernia, peristomal hernia, stricture of the stoma) in 18.3% of cases. Urological complications consisted of acute pyelonephritis (11%), ureteroileal stricture (4.9%) and urinary stones (4.9%). CONCLUSION: Bricker ileal conduit urinary diversion is associated with considerable mortality, especially in cancer patients. Early complications are essentially gastrointestinal, while late complications tend to be parietal or urological.

[Physiology of the anal and urinary sphincter apparatus for continence].

This report of the 27th congress of the Société Internationale Francophone d'Urodynamique (SIFUD) describes the mechanisms which allow the anal and urethral sphincter apparatus to ensure faecal and urinary continence. It successively described sphincter anatomy, the structure and ultrastructure of its muscle components, its innervation, neurotransmission and functioning regimens at rest, on effort and on straining. This study illustrates the differences but also the similarities of functioning of these two sphincter apparatuses. This can explain the high frequency of associated urinary and anal incontinence.

[Predisposing factors for ureteric strictures in renal transplantation].

OBJECTIVE: Renal transplantation is a well defined surgical procedure, but it nevertheless remains associated with a risk of medical and surgical complications. Ureteric strictures, with an incidence ranging from 2% to 7.5% according to the series, are the most frequent urological complication. The objective of this study was to determine the incidence of ureteric strictures and the existence of risk factors predisposing to the development of ureteric strictures and to evaluate their consequences on patient and graft survival, based on a single-centre retrospective series of renal transplantations. PATIENTS AND METHODS: From January 1990 to December 2002, 1787 renal transplantations were performed consecutively in our centre. Graft, donor and recipient characteristics were extracted from a computerized database and validated by an independent observer. The parameters studied included donor's age and recipient's age, donor's haemodynamic status and serum creatinine at the time of harvesting, cause of death, graft weight and number of graft arteries, cold ischaemia and reperfusion times, number of HLA incompatibilities and percentage anti-HLA immunization, time to return of graft function, acute rejection, presence or absence of a double J stent, episodes of acute pyelonephritis, CMV infection and patient and graft survival according to the Kaplan-Meier method. RESULTS: Ureteric stricture was observed in 74 patients (4.1% of cases) and a donor age greater than 65 years (p < 0.0001), the presence of more than 2 arteries on the graft (p = 0.03) and recipients with an anti-HLA immunization less than 25% (p = 0.037) were identified as independent risk factors. Furthermore, grafts complicated by ureteric stricture resumed function later (p = 0.001). The development of ureteric stricture did not have an unfavourable impact on the 10-year recipient and graft survival rates.

[Therapeutic management of ureteric strictures in renal transplantation].

OBJECTIVE: Ureteric strictures, with a reported incidence ranging from 2% to 7.5%, are the most frequent urological complication of renal transplantation. This article reports the results of open surgery and percutaneous or endoscopic techniques used to treat these strictures, based on a single-centre retrospective series of renal transplantations. PATIENTS AND METHODS: From January 1990 to December 2002, in a series of 1787 consecutive renal transplantations performed in our centre, 74 were complicated by ureteric stricture (4.1% of cases). Strictures occurred at the ureterovesical implantation in 82.4% of cases and during the first year in 88% of cases. The mean time to management of the stricture after transplantation was 9 months (range: 6 days-120 months). Criteria of success were defined by regression or even resolution of ultrasound signs of dilatation associated with stabilization of serum creatinine obtained by the external urinary diversion. Surgical or percutaneous revisions (particularly repeated changes of double J stents) were considered to be treatment failures. RESULTS: 44 strictures (59.5% of cases) were treated by open surgery and 30 (40.5%) were treated by a first-line endoscopic or percutaneous technique. In our hands, open surgical techniques (ureteropelvic anastomosis: 80% of success (n=5), ureterovesical reimplantation: 82% of success (n=11), ureteroureteric anastomosis: 100% of success (n=4)) gave better results than endourological techniques (endoscopic electrical incision: 61.5% of success (n=13), double J stent: 61.5% of success (n=13), balloon catheter dilatation: no success (n=4)). CONCLUSION: Classical open surgical revision remains the reference treatment for ureteric strictures in renal transplantation for our team.

[Results and surgical complications of pancreas transplantation with enteric exocrine drainage].

INTRODUCTION: The objective of this study was to evaluate the results and surgical complications of total pancreas transplantation with enteric exocrine drainage since the beginning of our experience with this type of transplantation. PATIENTS AND METHODS: From November 1999 to December 2002, 62 total pancreas transplantations were performed, consisting of 51 combined kidney-pancreas transplantations, 10 after renal transplantation and 1 pancreas-liver transplantation. Kidneys and pancreases were washed and stored in either Belzer solution or Celsior solution. Transplantation was performed via a midline transperitoneal incision with venous anastomosis at the root of the inferior vena cava (54 cases) or, more recently, in the superior mesenteric vein (8 cases). The arterial anastomosis was then performed in the right common iliac artery. Exocrine drainage was performed by side-to-side anastomosis between the donor duodenum and the recipient jejunum. The kidney was transplanted onto the left external iliac vessels and was extraperitonealised. RESULTS: The mean age of the recipients and donors was 41 +/- 9 years and 33 +/- 11 years, respectively. The mean cold ischaemia time was 14 +/- 5 hours. Four pancreases were lost due to venous thrombosis, 1 due to severe pancreatitis with haemodynamic collapse and venous thrombosis and another due to total necrosis of the duodenum. Seventeen patients (27%) were reoperated, including 10 during the first postoperative month and 7 during the first year. No cases of fistula of the gastrointestinal anastomosis were observed. All patients with a functional graft no longer required exogenous insulin. The actuarial patient and graft three-year survival was 96% and 86% respectively. CONCLUSION: Despite their high frequency, surgical complications did not have any harmful effects on either control of diabetes or graft and patient survival.

[Mixed epithelial and stromal tumour of the kidney].

The authors report the case of a patient with mixed epithelial and stromal tumour, a rare, recently described entity, as only 40 cases have been reported, mixed epithelial and stromal tumours are essentially observed in women during the perimenopausal period with a history of treatment with oestrogen-progestogens or gynaecological surgery. No clinical or radiological arguments can differentiate these tumours from other renal tumours. Histological examination reveals a tumour with an epithelial component and a stromal component presenting the characteristics of ovarian stroma and expressing oestrogen and progesterone receptors. The prognosis of these tumours is usually very favourable, although caution is advised in view of the limited number of published cases and a recent report of a malignant case.

[Ventriculo-ureteric shunt without associated nephrectomy for the treatment of hydrocephalus].

The authors report the case of a 51-year-old patient with hydrocephalus following posterior fossa surgery (cerebellar astrocytoma) treated by ventriculo-peritoneal shunt, then ventriculo-atrial shunt. After repeated valve revisions (diffuse peritoneal loculation, intracardiac thrombus responsible for dyspnoea and recurrent pulmonary embolism, shunt infections), another mode of shunting was required. The authors opted for ventriculo-ureteric shunt comprising ureteric reimplantation into a psoas bladder, without associated nephrectomy, which appears to constitute an alternative in the case of difficult surgical management of hydrocephalus or after failure of other modes of ventricular shunting.

[Ureteric catheter nephrostomy: simple and effective drainage after percutaneous nephrolithotomy].

The authors describe an original technique of postoperative drainage of percutaneous nephrolithotomy consisting of leaving a 5 F ureteric catheter in place, which descends into the bladder and drains into a conventional 18 or 20 F nephrostomy drain. It ensures ureteric drainage while eliminating the need for a urethral catheter, protects the nephrostomy tunnel by maintaining the nephrostomy drain in place and maintains access to the caliceal group used for percutaneous nephrolithotomy.

[Suspended congenital ureteral stricture].

The authors report a case of suspended congenital lumbar ureteric stricture in a 20-year-old woman following pyelonephritis with dilatation of the pyelocaliceal cavities. Assessment of this stricture demonstrated a vascular pedicle crossing in front of this zone, but with no signs of compression. Treatment consisted of retroperitoneal laparoscopic resection-anastomosis.

Prognostic value of bone scan in patients with metastatic prostate cancer treated initially with androgen deprivation therapy.

PURPOSE: We analyzed whether classifying bone prostate cancer metastases correlates with survival in patients treated primarily with androgen deprivation. MATERIALS AND METHODS: We identified 86 patients with bone metastases who were followed between September 1988 and September 1999. Only those treated initially with androgen deprivation as monotherapy were included in this study. Clinical, pathological and radiological information were obtained by patient chart review. The 86 patients were divided into 2 groups according to metastasis grade on bone scan at diagnosis. Group 1 included patients with metastases on the axial skeleton and group 2 included those with bone metastases on the appendicular skeleton. In addition to our classification, we stratified patients according to the Soloway and Crawford et al classifications, and analyzed survival. RESULTS: There were no statistical differences in the groups with axial versus appendicular metastases in terms of patient age, biopsy Gleason score, serum prostate specific antigen or clinical stage. Median survival was 53 and 29 months in patients with axial and appendicular bone metastases, respectively. Those with axial disease had better survival than those with appendicular bone metastases (p = 0.048). No statistical difference was observed when grading bone scan according to the Soloway and Crawford et al classifications. CONCLUSIONS: Classifying bone scans according to the site of metastases (axial versus appendicular) had many advantages. It is easy to understand and helps urologist better predict the patient prognosis. Axial metastases carries a better prognosis than appendicular metastasis.

[Prognostic factors of prostate cancer treated with first-line hormone therapy].

OBJECTIVE: Endocrine therapy of prostate cancer is designed to eliminate the action of androgens to prevent the growth of hormone-sensitive cancer cells. The duration and quality of the response to this treatment vary from one patient to another. The objective of this study was to evaluate the prognostic factors of patients treated by first-line endocrine therapy for prostate cancer. MATERIAL AND METHODS: From September 1988 to September 1999, 170 patients receiving first-line endocrine therapy for prostate cancer were included. Endocrine therapy consisted of LHRH analogues alone in 59.4% of cases, complete androgen suppression in 21.2% of cases, antiandrogens alone in 17.6% of cases and oestrogens in 1.8% of cases. Clinical, laboratory, scintigraphic and histological data were collected. The overall survival was studied by univariate analysis as a function of pretreatment criteria using Kaplan-Meier survival curves. RESULTS: The mean survival of the population was 33 +/- 26 months (range: 2-126 months). The following parameters were associated with a significant reduction of overall survival: age greater than 70 years, high ECOG score, mode of presentation of the cancer by alteration of general state, presence of bone pain, presence of bone metastases particularly in the appendicular skeleton, dilatation of renal cavities, Gleason score > 5, PSA level > 100 ng/ml, haemoglobin < 13.5 g/dl, serum creatinine > 105 mumol/l, low plasma testosterone, high alkaline phosphatase, poor response to treatment assessed by PSA greater than 4 ng/ml at 3, 6 and 12 months. CONCLUSION: Determination of these prognostic factors can be used to predict the patient's response to endocrine therapy and survival. These factors can also be used to stratify patients in comparable groups for clinical trials.
