Abstract
BACKGROUND Upper-tract-urothelial-carcinoma (UTUC) represents 5-10% of all urothelial-neoplasms with increasing incidence in the last decades. Current standard tools for diagnosis of UTUC include cytology, computed tomography (CT) urography and ureterorenoscopy (URS). The aim of this study was to evaluate the impact of Bladder Epicheck® Test as diagnostic tool for UTUC diagnosis and recurrence. METHODS Overall, 136 urine samples, selective collected from upper-urinary-tract before URS for suspicion of UTUC were analyzed with cytology and Bladder Epicheck® Test. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of both markers were calculated and compared to URS and/or histology as reference. RESULTS UTUC was detected in 40 cases (33.3%), among them 30 were classified as low-grade (LG) and 10 as high-grade (HG). Overall sensitivity of Bladder Epicheck® for UTUC detection was 65% compared to 42.5% for cytology, increasing to 100% for Bladder Epicheck® and 90% for cytology if considering only HG tumors. Overall specificity of Bladder Epicheck® was 81.2% and of cytology 93.7%. PPV and NPV were 63.4% and 82.2% for Bladder Epicheck® and 77.2% and 76.5% for cytology. Considering an EpiScore cut-off >75, instead of 60, specificity of Bladder Epicheck® improves to 89% and PPV to 74.2%. Limitations include the use of a marker validated only for bladder-cancer and the relatively small number of cases. CONCLUSIONS Due to its high sensitivity for HG tumors, the Bladder Epicheck® Test can be used in diagnosis and treatment decision-making of UTUC. Furthermore, it could be very useful in follow-up of UTUC, after endoscopic treatment to postpone or avoid unnecessary endoscopic exploration. Even if further studies are needed to validate these findings, Bladder Epicheck® could be a promising clinical tool for detection of UTUC.

Abstract
Flexible ureteroscopy (fURS) is a well-established procedure for treating multiple upper-urinary tract pathologies, particularly renoureteral lithiasis. Endoscopes have undergone significant advancements, including miniaturization, improved optics, and increased maneuverability. In addition, advancements in accessory instruments, such as the performance of laser fibers, guidewires, and extraction probes, have played a significant role in improving the overall performance of flexible ureteroscopy procedures. However, despite these advancements, unique circumstances can make achieving optimum results during flexible ureteroscopy challenging. These include congenital renal anomalies (horseshoe kidneys, ectopic kidneys, rotation anomalies), as well as the unique intrarenal anatomy (infundibulopelvic angle, infundibular length) or the specifications of the endoscope in terms of maneuverability (active and passive deflection). This review explored challenging scenarios during flexible ureteroscopy procedures in the pyelocaliceal system.

Abstract
Renal papillary hypertrophy is a rare variation that mimics upper tract urothelial carcinoma. This is the ninth case in literature. It causes hematuria and pain, or it could be asymptomatic. It is important to distinguish this variation from malignant masses since misdiagnosis leads to unnecessary radical surgery. Flexible ureteroscopy helps distinguish malignant from benign masses, particularly in cases where there is not a consensus on the exact pathology of the mass. We present a 46-year-old female who came with hematuria and was planned to undergo radical nephroureterectomy under the impression of renal cell carcinoma based on imaging studies. After flexible ureteroscopy, renal papillary hypertrophy was confirmed and radical nephroureterectomy was prevented.

Abstract
Upper tract urothelial carcinoma (UTUC) is a relatively rare disease that accounts for 5% to 10% of all urothelial carcinomas (UCs). Radical nephroureterectomy (RNU) with a bladder cuff is the current gold standard for the management of UTUC; however, endoscopic ablation is also an option for low-risk UTUC to preserve kidney function. Herein, we present two cases of solitary kidney with a right lower ureteral tumor. Both patients underwent left RNU in the past. An 82-year-old man with a right ureteral tumor whose histopathological examination revealed low-grade UC. Laser ablation was performed with ureteroscopy, and there was no recurrence for 7 years after treatment. A 67-year-old woman with a right lower ureteral tumor whose histopathological examination also revealed low-grade UC. Laser ablation was performed, and there was no recurrence for 5 years after the treatment. We closely followed-up our two patients after RNU. This allowed for early detection of tumor recurrence, after which we could perform laser ablation therapy.

Abstract
INTRODUCTION We report a rare case of an extramedullary plasmacytoma of the ureter. CASE PRESENTATION A 77-year-old man was referred to our hospital because of left hydronephrosis. Computed tomography showed a tumor in the left ureter, and tumor invasion into the periureteric fat was suspected. Urine cytology showed Eatypical cells whose nuclei were hyperchromatic (class IIIb). The left ureteral tumor was diagnosed as urothelial carcinoma (cT3N0M0) preoperatively. Subsequently, we performed laparoscopic radical nephroureterectomy with bladder cuff excision. The tumor was pathologically diagnosed as a plasmacytoma. Postoperative positron emission tomography did not reveal abnormal uptake, and bone marrow aspiration findings were normal. Consequently, the left ureter tumor was diagnosed as an extramedullary plasmacytoma of the ureter. CONCLUSION Extramedullary plasmacytoma commonly occurs in the upper respiratory tract or upper gastrointestinal tract. Extramedullary plasmacytoma of the ureter is rare. This is only the fourth reported case of extramedullary plasmacytoma of the ureter.

Abstract
Upper urinary tract urothelial cell carcinoma (UTUC) with venous tumor thrombus (TT) that extends into the renal vein (RV) and inferior vena cava (IVC) is a rare entity and its management is a surgical challenge. We report the largest single experience of surgical management of UTUC and accompanying venous TT with radical nephroureterectomy and tumor thrombectomy (RNATT) using transplant-based (TB) surgical techniques. From September 2003 to June 2021, nine patients with UTUC and venous TT underwent RNATT. Demographics, disease characteristics, surgical details, 30-day postoperative complications, and overall survival (OS) were analyzed. All nine patients had extension of the TT into the RV. Of those, seven had additional extension of the TT into the IVC. Venous TT level was categorized as 0 (n = 2), I (n = 2), II (n = 4), and IIIa (n = 1). Median tumor size was 12 cm (range 3–20 cm). Median estimated blood loss was 300 (range 150–1000) cc. One patient was still alive at last follow-up (4 months), and in total, eight patients have died with a median time-to-death of 12 months (range 10 days–24 months). RNATT using TB maneuvers like liver mobilization and pancreas-spleen en bloc mobilization provide excellent exposure to the retroperitoneal space and enable the safe removal of UTUC with venous TT.
