Background

The association between tumor complexity and postoperative complications after partial nephrectomy (PN) has not been well characterized.

Objective

We evaluated whether increasing renal tumor complexity, quantitated by nephrometry score (NS), is associated with increased complication rates following PN using the Clavien-Dindo classification system (CCS).

Design, setting, and participants

We queried our prospectively maintained kidney cancer database for patients undergoing PN from 2007 to 2010 for whom NS was available.

Interventions

All patients underwent PN.

Measurements

Tumors were categorized into low- (NS: 4-6), moderate- (NS: 7-9), and high-complexity (NS: 10-12) lesions. Complication rates within 30 d were graded (CCS: I-5), stratified as minor (CCS: I or 2) or major (CCS: 3-5), and compared between groups.

Results and limitations

A total of 390 patients (mean age: 58.0 ± 11.9 yr; 66.9% male) undergoing PN (44.6% open, 55.4% robotic) for low- (28%), moderate- (55.6%), and high-complexity (16.4%) tumors (mean tumor size: 3.74 ± 2.4 cm; median: 3.2 cm) from 2007 to 2010 were identified. Tumor size, estimated blood loss, and ischemia time all significantly differed (p < 0.0001) between groups; patient age, body mass index (BMI), and operative time were comparable. When stratified by CCS, minor and major complication rates for all patients were 26.7% and 11.5%, respectively. Minor complication rates were comparable (26.6 vs 24.9 vs 32.8%; p = 0.45), whereas major complication rates differed (6.4 vs 11.1 vs 21.9%; p = 0.009) among tumor complexity groups. Controlling for age, gender, BMI, type of surgical approach, operative duration, and tumor complexity, prolonged operative time (odds ratio [OR]: 1.01; confidence interval [CI], 1.0-1.02) and high tumor complexity (OR: 5.4; CI, 1.2-24.2) were associated with the postoperative development of a major complication. Lack of external validation is a limitation of this study.

Conclusions

Increasing tumor complexity is associated with the development of major complications after PN. This association should be validated externally and integrated into the decision-making process when counseling patients with complex renal tumors.  相似文献

A bleeding renal artery pseudoaneurysm is a recognised complication occurring after partial nephrectomy. The bleeding is usually suspected when a patient presents with haematuria following the procedure and the reported management is with radiologically guided embolisation. We report a case of renal artery pseudoaneurysm successfully managed conservatively, giving another potential management option in non-torrential haemorrhage.  相似文献

Abstract Renal artery pseudoaneurysms are a well‐documented complication following trauma or percutaneous urological procedures, but are rare after partial nephrectomy. We present the case of a 34‐year‐old woman who, after undergoing a left nephrectomy in childhood due to Wilms’ tumor, had a pseudoaneurysm in a solitary kidney after laparoscopic right partial nephrectomy with extraperitoneal approach for a renal cell carcinoma. The segmental renal artery feeding the pseudoaneurysm was embolized with coils without significant loss of residual renal function.  相似文献

Objectives

The aim of this study was to analyze the outcomes of surveillance after partial nephrectomy (PN) in a single institution and the relevance of imaging studies in detecting recurrence.

Material and methods

Retrospective study of 830 patients who underwent PN for localized renal cell carcinoma between 2007 and 2015 at a single institution. We studied the characteristics of recurrence according to pathological and clinical features and elaborated risk groups. The type and the total number of imaging studies performed during surveillance or until recurrence were evaluated. Outcomes of surveillance were analyzed.

Results

There were 48 patients (5.8%) diagnosed with recurrence during median 36 [21–52] months follow-up, including local recurrence in 18 patients (37.5%) and metastasis in 30 patients (62.5%). Totally, 17/18 patients (94.4%) with local recurrence and 26/30 patients (86.6%) with metastasis were diagnosed within the first 36 months after PN. When studying the recurrence rate, and time-to-recurrence, 2 risk groups emerged. Patients with pathological characteristics (tumors with pT1b or higher or high-grade tumor or positive surgical margin status) or patients with anatomical characteristics (high or moderate R.E.N.A.L. score) or both had high recurrence rate. Chest x-ray and abdominal ultrasound detected 7.7% and 3.4% of all recurrences, respectively, whereas computed tomography scan and magnetic resonance imaging scan detected the rest. Of the 48 patients diagnosed with recurrence, 44 (91.6%) were suitable for secondary active treatment (systemic, surgery, and radiotherapy) including 26 (54.2%) suitable for metastasectomy. The rate of relapse after secondary treatment was 43.5% (16.6% for the local recurrence group and 60.7% for metastasis group).

Conclusion

Local recurrence emerges earlier than distant metastasis. Patients with any adverse pathological or anatomical features should be considered as high-risk group and followed closely in the first 36 months after PN with cross-sectional studies. Secondary active treatment is suitable for most patients, while surgical treatment fits fewer patients. Local recurrence is associated with increased rates of metastatic progression.  相似文献

Renal artery pseudoaneurysm following laparoscopic partial nephrectomy   总被引:3,自引:0,他引:3  
Singh D  Gill IS 《The Journal of urology》2005,174(6):2256-2259
PURPOSE: We describe the presentation, evaluation and management of hemorrhage due to renal artery pseudoaneurysm following laparoscopic partial nephrectomy. MATERIALS AND METHODS: Of the 345 laparoscopic partial nephrectomies performed by us during a 5-year period 6 patients (1.7%) had postoperative hemorrhage from a renal artery pseudoaneurysm. Patient charts were reviewed to identify pertinent preoperative, intraoperative and postoperative data. RESULTS: Median tumor size was 3.5 cm (range 2.2 to 5), intraoperative blood loss was 175 cc (range 50 to 500), warm ischemia time was 32 minutes (range 30 to 45) and operative time was 3.8 hours (range 2.5 to 5). The mean percent of kidney excised was 31% and pelvicaliceal system entry was suture repaired in all 6 patients. No patient required blood transfusion perioperatively. Average hospital stay was 3.4 days (range 2.5 to 6). Delayed postoperative hemorrhage occurred at a median of 12 days (range 8 to 15). Angiography revealed a renal artery pseudoaneurysm most commonly at a third or fourth order branch (4 and 2 patients, respectively). Percutaneous embolization was successful in each patient. CONCLUSIONS: Renal artery pseudoaneurysm is an uncommon complication following laparoscopic partial nephrectomy. These patients often present in delayed fashion. Selective angiographic embolization is the initial treatment of choice.  相似文献
