Survival of patients with bilateral renal cell cancer after nephro-preserving surgery

This article presents a systematic literature review to assess the survival outcomes of patients with bilateral renal cell carcinoma who underwent nephro-preserving surgery. Patients with bilateral renal neoplastic lesions represent a rare subpopulation, numbering, according to different authors, from 2 to 6 % of the total RCC group. Despite the increase in the number of cases of bilateral RCC, the number of works devoted to the study of the features of surgical intervention, prognosis factors, treatment outcomes and survival of this cohort of patients is limited, and a number of important questions regarding this problem remain unresolved. Currently, the only effective method of treating bilateral renal cancer is nephro-preserving surgery in the volume of bilateral renal resection / nephrectomy with resection of the contralateral kidney in case of synchronous lesion or resection of a single kidney in case of metachronous lesion. This strategy avoids or reduces the risk of developing renal failure and its consequences after surgery. Conclusion. Nephro-preserving surgery for bilateral renal cell carcinoma is the only effective method to achieve satisfactory oncological results with a low incidence of complications.

Case Report: Bilateral Renal Cell Carcinoma With Different Histological and Morphological Features, Clear Cell and Cystic Thyroid-Like Follicular Subtype

Thyroid-like follicular renal cell carcinoma is a rare subtype of renal cell carcinoma that has only been recently recognized, as most cases involve a solid tumor in one kidney. In this study, we report a rare case of bilateral renal cell carcinoma wherein the tumor in the left kidney was diagnosed as clear cell carcinoma, while the tumor in right kidney as thyroid-like follicular renal cell carcinoma. The difference between this case and the ones described in previous reports is that thyroid-like follicular renal cell carcinoma showed cystic changes on imaging. This suggests that when renal cystic lesions are encountered, we should consider the possibility of such rare tumors.

Bilateral Single-Stage Nephrectomy for Synchronous Bilateral Renal Cell Carcinoma

Bilateral synchronous renal cell carcinoma (RCC) is uncommonly encountered. Debate exists among urologists in managing these cases in a single surgery versus staged surgeries. We aim to report our experience in managing encountered cases using single-stage surgeries. Retrospective collection of cases with pathologically confirmed RCC that had single-stage bilateral renal surgery over the past 2 years. Three cases were identified. Patients were managed using bilateral transverse lateral lumbotomy. All patients did not have intraoperative or postoperative complications. Kidney function stayed stable after surgery. Single-stage bilateral renal surgery is a safe procedure. Bilateral transverse lateral lumbotomy allows for a fast and safe surgery with minimal complications. There is a possible histological disconcordance in bilateral synchronous RCC.

Bilateral renal cell carcinoma of the native kidneys in a 16-year-old boy: Report of a rare case and review of the literature

Bilateral renal cell carcinoma is rare and most commonly occurs in patients with background of hereditary and genetic diseases. Occurrence of bilateral renal cell carcinoma in native kidneys of a renal transplant patient is even more uncommon, and less than 10 cases have been reported in the English literature. Herein, we report our experience with the youngest renal transplant patient ever reported with bilateral renal cell carcinoma, who presented with intractable urinary tract infection. We also will review all of the reported cases of bilateral renal cell carcinoma in the last 20 years in the English literature according to the presentations, treatment modalities, prognosis, and graft outcome.
