Morbidity is high for this procedure, and ureteral stenosis with consequent renal damage is a possible complication for all types of urinary diversions. The endoscopic approach is a therapeutic option although it is not very effective. Open surgery is more effective, but is associated with significant morbidity. Laparoscopic approach has not been widely used because of its relative contraindication in patients with previous abdominal surgery, and because of its technical challenge. Purpose: To display the surgical technique, step by step, of the laparoscopic ureteroureterostomy in orthotopic neobladder.

This overexpression of FR in renal-cell carcinoma (RCC) can be exploited by attaching nearly any therapeutic or imaging agent for delivery to cancer cells. In one of its first applications, platinum-resistant ovarian cancer, folate was used to deliver pegylated liposomal doxorubicin (a folate-linked vinca alkaloid) and improved progression-free survival versus standard treatment. RCCs are thought to be the second highest FR-expressing cancer. OTL-38 is a folate analogue conjugated with a fluorescent dye that emits light in the near infrared spectrum. This longer wavelength allows for deeper penetration of the fluorescent light through tissues with the potential to better image tumors beneath adipose tissue or deeper into organ parenchyma. We are currently conducting a pilot, phase 2, nonrandomized study in patients with RCC, scheduled to undergo primary, partial, or radical nephrectomy. The aim is to explore the use of OTL-38 and fluorescence imaging to observe RCC at the margins of resection in partial nephrectomy and in lymph node(s) or other metastases for radical nephrectomy. <b><i>Methods:</i></b> Currently two patients have participated in the trial to date with an accrual target of 20 patients. The first was a 67-year-old male with an incidental 2.2 cm right-sided renal mass, and the second was a 70-year-old male with an enlarging 2 cm renal mass. Per protocol, both patients were administered OTL-38 in the preoperative area 1 hour before the procedure. Subsequently, both procedures were performed with robotic assistance as per normal routine with the use of Firefly fluorescence to aid in observation of OTL-38 uptake. <b><i>Results:</i></b> Intraoperative guidance through OTL-38 demonstrated minimal to no uptake of the OTL-38 as seen by Firefly fluorescence (green color). Surprisingly, the normal renal parenchyma showed strong uptake of OTL-38 as seen by Firefly fluorescence. Both pathology reports revealed conventional clear cell RCC. Immunohistochemistry slides of the tumor revealed only mild staining for folate. In contrast, immunohistochemistry slides of the normal renal parenchyma in the surgical margin revealed a strongly positive stain for folate. <b><i>Conclusions:</i></b> In conclusion, our first two patients' renal tumors did not stain strongly for folate; however, the normal renal parenchyma did, which served as an intraoperative guide to confirm a negative margin. Further study of patients will reveal whether folate receptors are, in fact, predominant or not in renal cell cancer. No competing financial interests exist.

Daneshmand","doi":"10.1089/vid.2015.0054","DOIUrl":"https://doi.org/10.1089/vid.2015.0054","url":null,"abstract":"Abstract Introduction: Blue light cystoscopy (BLC) using hexaminolevulinic acid has been shown to improve the detection of nonmuscle invasive bladder cancer (NMIBC) during transurethral resection of bladder tumors.1–3 Although the FDA has not yet approved BLC for the detection of carcinoma in situ (CIS), both the European Association of Urology and the International Consultation on Urological Diseases recommend it based on the evidence from clinical trials. Despite the lack of recommendation for repeat use or re-resection, a number of trials have shown the significant improvement in detection of recurrent papillary tumors.2 BLC results in lower recurrence rate and a better recurrence-free survival, but no study, to date, has shown a progression benefit.4 Overall, the false-positive proportion rate of BLC is 12% while it was 10% with white light (WL) alone. In this video, we demonstrate the use of Cysview® for the detection of different stages of urothelial carcinoma, its role in detection of cancer in the margin of previous resection, and the efficacy of BLC in detecting concealed or tumor obscured ureteral orifices. Materials and Methods: From April 2012 to May 2015, 252 patients underwent BLC and transurethral resection of bladder tumor (TURBT) at our institution. Several cases are highlighted in the video demonstrating cystoscopic view under WL and blue light (BL) with pathology results. Results: BLC with Cysview is demonstrated in a number of challenging cases for the detection of NMIBC. The positive bright red areas were biopsied and revealed urothelial carcinoma in each case. The first case shows a papillary tumor on the right lateral wall with WL. The tumor was clearly positive under BL (bottom left) with final pathology showing high-grade T1 urothelial carcinoma. BLC also identified an additional flat lesion extending from the area of the tumor, which was not detected using WL alone (pathology was consistent with CIS). The second patient shows the bed of a previous resection site, which is completely negative on WL but positive with BL. Final pathology revealed CIS in this case. The last case demonstrates an obvious papillary lesion on the left hemitrigone that was positive under BL as well (which was a high-grade Ta tumor). Additionally, we were able to identify previously undetected tumor in the left ureteral orifice as well as a BL-positive flat lesion surrounding the orifice (CIS on pathology). Another useful aspect of BLC is the ability to identify a urine jet (as a green hue) from the ureteral orifice without the use of methylene blue or indigo carmine. This feature is especially helpful in cases where the ureteral orifice cannot be easily identified secondary to anatomical variation or overlying tumor. There were 10 (4%) minor complications after Cysview instillation (all mild irritative symptoms), but no hypersensitivity reaction even on repeat use (40 procedures). Conclusions: The use of BLC with Cysview can help with the detecti","PeriodicalId":92923,"journal":{"name":"Journal of endourology.
