A case of familiar bilateral multicentric RCC in a young woman is an ideal model to evaluate preoperative and intraoperative diagnostic and surgical tools in order to achieve two distinct goals: the oncologic radicalness and the renal function preserved. Radical bilateral nephrectomy, the renal hypothermia by perfusion of both kidneys, the bench high resolution sonography of parenchyma, the choose of one kidney suitable for conservative surgery, the resection of suspect lesions with intraoperative pathology, the reconstructive bench surgery, the autotransplantation, are the steps accurately performed with particular concern to eradication of all the tumoral lesions present in the kidneys. The results confirm that renal function has been preserved with this method. Radicalness should be appointed by a longlasting follow up. However, as it is discussed, conservative surgery, when accurately performed can give results not different from radical demolitive surgery. In this paper tools to improve diagnostic and therapeutic methods are described in order to increase the diagnostic accuracy and the therapeutic efficacy. The possibility that this multiple RCC can be a part of the abnormalities occurring in the Von Hippel-Lindau syndrome does not change the surgical approach, being the RCC the worst prognostic factor of the syndrome.

NS-21, (+/-)-4-diethylamino-1,1-dimethylbut-2-yn-1-yl 2-cyclohexyl-2-hydroxy-2-phenylacetate monohydrochloride monohydrate, is a new drug for the treatment of urinary frequency and incontinence. To evaluate acute toxicities of its related compounds including the optical isomers of NS-21 ((S)NS-21 and (R)NS-21), the active metabolite of NS-21 ((R/S)RCC-36), the optical isomers of (R/S)RCC-36 ((S)RCC-36 and (R)RCC-36), the hydrolysis products of NS-21 (RCC-32 and RCC-38) and the bi-product of NS-21 (RCC-66), single-dose intraperitoneal toxicity studies were conducted in ddY mice. The LD50 values of these compounds in male and female mice were as follows: 199 and 184 mg/kg for (S)NS-21, 261 and 240 mg/kg for (R)NS-21, 74 and 100-150 mg/kg for (R/S)RCC-36, 93 mg/kg for (S)RCC-36 in both sexes, 83 and 104 mg/kg for (R)RCC-36, higher than 510 mg/kg for RCC-32 in both sexes, 340-510 mg/kg for RCC-38 in both sexes, and 1000-2000 mg/kg for RCC-66 in both sexes, respectively. The clinical signs included decreased spontaneous locomotor activity, prone or lateral position, ataxic gait, clonic convulsion, hypopnea, hypothermia, pale skin, mydriasis, abdominal distention and unkempt fur for (S)NS-21, (R)NS-21, (R/S)RCC-36, (S)RCC-36 and (R)RCC-36, decreased spontaneous locomotor activity, prone position, ataxic gait, clonic convulsion, tail elevation and hypopnea for RCC-32 and RCC-38, and decreased spontaneous locomotor activity and unkempt fur for RCC-66. Body weight was decreased or its gain was suppressed for every compound examined. Pathological examination of the dead mice showed atrophy of the thymus and spleen, intestinal distention with the retention of dark red contents, white spots or white materials in the abdominal fatty tissue for (S)NS-21, (R)NS-21, (R/S)RCC-36, (S)RCC-36, (R)RCC-36 and RCC-66, but no treatment related change for RCC-32 and RCC-38. Adhesion between the abdominal organs was observed in survivors treated with (S)NS-21, (R)NS-21, (S)RCC-36, (R)RCC-36, RCC-32 and RCC-66.
