OBJECTIVE: To investigate the effects of MetS on the prognosis of patients with clear cell renal cell carcinoma (ccRCC). METHODS: Clinical and pathological data and the laboratory test of ccRCC 342 patients with diverticular stones who underwent ccRCC who underwent radical or partial nephrectomy were retrospectively collected and analyzed.The patients were divided into MetS group and non-MetS group, and the subgroups were defined according to the tumor size. The overall survival (OS), cancer-specific survival (CSS), and progression-free survival (PFS) of the two groups were analyzed by univariate Cox analysis, and the subgroup analyses were also performed. Kaplan-Meier survival curve and survival analysis for OS, CSS, and PFS of the two groups and the subgroups were conducted. RESULTS: Univariate Cox analysis showed that MetS was a protective factor of postoperative OS [hazard ratio (HR)=0.551, 95%CI: 0.321-0.949, P=0.031], CSS (HR=0.460, 95%CI: 0.234-0.905, P=0.025), and PFS (HR 0.585, 95%CI: 0.343-0.998, P=0.049) in the patients with ccRCC. In the subgroup with tumor size≤4 cm, MetS was not associated with postoperative OS (HR=0.857, 95%CI: 0.389-1.890, P=0.702), CSS (HR=1.129, 95%CI: 0.364-3.502, P=0.833), and PFS (HR=1.554, 95%CI: 0.625-3.864, P=0.343). In the subgroup with tumor size>4 cm, Mets was a protective factor of postoperative OS (HR=0.377, 95%CI: 0.175-0.812, P=0.013), CSS (HR=0.280, 95%CI: 0.113-0.690, P=0.006), and PFS (HR=0.332, 95%CI: 0.157-0.659, P=0.002); Obesity was a protective factor of postoperative CSS (HR=0.464, 95%CI: 0.219-0.981, P=0.044), and PFS (HR=0.445, 95%CI: 0.238-0.833, P=0.011). Kaplan-Meier survival analysis showed that the long-term survival of patients with MetS was better than those without MetS in OS (P=0.029), CSS (P=0.021), and PFS (P=0.046); for the subgroup with tumor size≤4 cm, there was no significant difference in postoperative OS (P=0.702), CSS (P=0.833), and PFS (P=0.339) between patients with and without MetS; For the subgroup with tumor size>4 cm, the OS (P=0.010), CSS (P=0.003), and PFS (P=0.001) of patients with MetS were better than those without MetS. CONCLUSION MetS was a protective factor of postoperative OS, CSS, and PFS in the patients with ccRCC, which was more obvious in subgroup with tumor size>4 cm. And obesity, the component of MetS, was correlated with postoperative OS and CSS.

Peripheral neuropathy or amyotropic lateral sclerosis can be associated with renal cell carcinoma. We report a 63-year-old male patient with renal cell carcinoma who developed an atypical, progressive neuropathy after nephrectomy.

An adenocarcinoma arising in a horseshoe kidney (HK) is rare. The case of a forty five-year-old male patient, presenting with a recurrent, painless hematuria, is reported. On investigation the patient was found to have a horseshoe kidney, with an adenocarcinoma in the left hemi-kidney, which was treated surgically, with a hemi-nephrectomy, of the involved part, being performed to excise the tumor. A brief review of the relevant literature is also presented.

OBJECTIVETo evaluate the alterations in renal function after radical nephrectomy (RN) and partial nephrectomy (PN) for renal cell carcinoma (RCC) and to determine the risk factors for the onset of postoperative renal function impairment.

METHODSWe assessed the renal function of 429 T1a RCC patients by investigating the time-dependent changes of the estimated glomerular filtration rate (eGFR) after surgery from August 2003 to August 2010. Univariate and multivariate regression models were used to determine the risk factors for the onset of an eGFR < 60 ml · min⁻¹ · 1.73 m⁻² function, and to evaluate the prognosis for the two groups.

RESULTSThe mean eGFR values (ml · min⁻¹ · 1.73 m⁻²) at postoperative 1, 7 days, 1, 3, 6, 12 and 24 months were 51.4 ± 12.6, 52.1 ± 17.8, 53.2 ± 19.5, 54.6 ± 20.2, 53.8 ± 16.6, 52.7 ± 22.3 and 51.5 ± 18.4 in the RN group and 69.6 ± 18.3, 70.3 ± 19.5, 71.5 ± 21.4, 76.2 ± 22.8, 75.4 ± 19.7, 74.3 ± 16.3 and 73.1 ± 23.2 in the PN group, respectively. The eGFR of the radical nephrectomy group was significantly lower than that of the partial nephrectomy group (P < 0.05). Multivariable analysis revealed that radical nephrectomy and age were risk factors for the onset of postoperative chronic renal dysfunction.

CONCLUSIONSRenal function recovered partially after partial and radical nephrectomy and is maintained constantly after 3 months. Surgical mode and age are risk factors for the onset of postoperative eGFR < 60 ml · min⁻¹ · 1.73 m⁻² impairment. Compared with radical nephrectomy, partial nephrectomy can preserve renal function and reduce the incidence of postoperative chronic renal dysfunction.

From January 2008 to January 2013, 11 patients with central renal tumors underwent ultrasound-guided open nephron sparing surgery (ONSS) without renal artery occlusion. We removed the lesions, and the cut edges of the tumors were negative. Thus, we deduced that ultrasound-guided ONSS is suitable for the cases with obscure tumor boundary or multiple lesions. It could achieve the purpose of thoroughly removing lesions, as well as to expand the application range of nephron sparing surgery.
