目前,开放性肾部分切除术仍被认为是治疗小肾癌的标准术式,而腹腔镜下肾部分切除术是一种保留肾单位治疗小肾癌的微创方法.单纯肿瘤剜除术对于选择性的小肾癌患者是一项可接受的、安全的保留肾单位治疗方法,相对于肾部分切除术,它并不增加局部复发的风险.消融技术则给微创下进行保留肾单位手术带来新的方法和新的思路. 相似文献

保留肾单位手术与根治性肾切除术治疗小肾癌疗效的对照研究 总被引:2,自引:1,他引:2
评价保留肾单位手术与根治性肾切除术治疗小肾癌疗效,回顾性分析83例肿瘤直径≤4 cm的小肾癌手术治疗的效果,其中保留肾单位手术44例,根治性肾切除术39例.保留肾单位手术与根治性肾切除术相比,术中平均出血量、术后3 d引流量、并发症的发生率以及术后肿瘤复发和转移情况作为评价指标.结果两组患者均顺利完成手术.NSS组与RN组术中出血量分别为[(130±11.5) mL vs (110±10.7) mL];术后3 d引流量两组分别为[(110±8.6) mL vs (96±8.1) mL];并发症发生率(1/44 vs 1/39),两组之间差异无统计学意义.NSS组随访6~86个月(平均46个月),RN组随访8~86个月(平均48个月),均未发现局部复发和远处转移.初步研究结果提示,保留肾单位手术可以最大限度地保存残肾的肾单位和功能,是小肾癌患者有效和可靠的治疗方法,目前仍被认为是小肾癌治疗的金标准.中华肿瘤防治杂志,2009,16(13):1033-1035 相似文献

With the advent of cross-sectional imaging, the incidence of asymptomatic detected small renal masses, 'incidentalomas', has increased in the past 20 years. Recent studies have demonstrated that patients with renal masses have worse renal function at baseline and have more comorbidities than the general population. Nephron-sparing surgery allows for maximal preservation of functioning nephrons with comparable oncologic outcomes. Recently, laparoscopic partial nephrectomy has emerged as a minimally invasive nephron-sparing surgical option for treating the appropriately selected renal mass. While open-partial nephrectomy has undisputedly become standard of care for the management of the small renal mass (<4 cm), laparoscopic partial nephrectomy is becoming the preferred option for select patients in institutions in which advanced laparoscopic experience is available. 相似文献

Currently, up to 60% of renal tumors are detected incidentally by abdominal imaging. Most of these tumors are small and localized to the kidney. Owing to the shift to lower stage at diagnosis, radical nephrectomy has fallen out of favor and has been replaced by nephron-sparing surgery. Currently, partial nephrectomy is the treatment of choice for patients with small renal tumors. As the trend towards less invasive therapy continues, laparoscopic and percutaneous ablation techniques have gained popularity for the treatment of renal tumors in patients who are high-risk surgical candidates, or have a solitary kidney, limited renal function or multifocal disease. Percutaneous radiofrequency ablation is a safe, minimally invasive treatment option for those patients. 相似文献

Radical tumor nephrectomy is the standard procedure for the treatment of renal cancer. Nowadays small renal solid masses are more frequently diagnosed that do not justify the radical approach of tumor nephrectomy, which is associated with the loss of the entire organ. Open partial nephrectomy still remains a challenging surgical approach which does not fulfil the criteria of minimal invasiveness. This opens the room for minimally invasive approaches in the sense of a “nephron-sparing therapy”. Laparoscopic partial nephrectomy is a very attractive, but technically challenging method for the definitive treatment of small renal masses. Beside this, tissue ablative methods such as cryotherapy or radiofrequency ablation have been developed and seem to be effective. The absence of long-term follow-up data for tumor control and patient survival is the current major concern of the general application of the new therapeutic strategies. Therefore, these therapies should only be tested in clinical trials. 相似文献

Fergany A 《Clinical genitourinary cancer》2006,5(1):26-33
Localized renal cell carcinoma (RCC) remains a surgical disease, with excision of the tumor or tumor-bearing kidney offering the only chance of cure for affected patients. After the widespread acceptance of partial nephrectomy as equivalent treatment to radical nephrectomy in appropriately selected cases of RCC, a range of nephron-sparing procedures has become available to patients. These include laparoscopic partial nephrectomy, thermal ablative techniques, as well as open partial nephrectomy. These techniques offer the attraction of being minimally invasive, in some cases as outpatient procedures under sedation. This review attempts to clarify the current status of these nephron-sparing techniques. Case selection criteria, outcomes, and complications are presented with the aim of helping the modern urologist appreciate the benefits of these procedures as well as their limitations and role in the management of patients with RCC. 相似文献

Although radical nephrectomy is a "standard" surgery for management of renal cell carcinoma, nephron-sparing surgery has become accepted for selected patients: those with solitary kidney, bilateral renal cell carcinoma or small renal cell carcinoma. Recently laparoscopic surgery has gradually come to include nephron-sparing surgery with minimum invasiveness. Furthermore, new methodologies such as cryoablation and radiowave ablation enable percutaneous management of nephron-sparing surgery. Thus, nephron-sparing surgery is becoming less invasive. However, its efficacy in controlling cancer needs to be discussed further. 相似文献

In an effort to decrease operative morbidity, energy based ablative procedures have triggered considerable interest in the treatment of select, small (<3 cm) renal tumors. Renal cryoablation for small renal tumors is a well-studied energy based ablative procedure that shows considerable promise as an alternative to partial nephrectomy. Cryoablation is minimally invasive and has demonstrated acceptable intermediate-term results. In this article we review key laboratory research and current clinical series of renal cryoablation. 相似文献

Radical tumor nephrectomy is the traditional standard procedure for the treatment of renal cancer. Nowadays, small renal solid masses are more frequently diagnosed, and elderly patients are often confronted with substantial co-morbidities. Given this situation, radical tumor nephrectomy with the loss of the entire organ no longer seems to be the treatment of choice. Open partial nephrectomy still remains a challenging surgical approach with a complication rate of up to 20%, which does not fulfill the criteria of minimally invasiveness. This opens the room for innovative, minimally invasive therapeutic approaches. Laparoscopic partial nephrectomy is a very attractive, but technically challenging method for the definite treatment of small renal masses. Compared to open partial nephrectomy, the laparoscopic approach is associated with a higher incidence of complications and re-operations. Therefore, laparoscopic partial nephrectomy is not yet accepted as a standard procedure and should currently be reserved for experienced centers. Beside this, tissue-destructive, so called tissue-ablative methods such as cryotherapy or radiofrequency ablation, are gaining more and more clinical importance and seem to be effective. The absence of long-term follow-up data for local tumor control and patient survival are the current major concerns for the routine application of the new ablative techniques. Therefore, these therapies should only be tested in clinical trials or for selected patients in whom a curative surgical approach is not possible. Another option for patients with small renal masses is active surveillance. Recent data have shown that the average growth rate of small tumors is only some millimeters per year. Given these observations, active surveillance might be an initial alternative option for selected high risk patients. 相似文献
