18F-FDG PET/CT features of ureteral metastases from breast cancer: a case report.

J Int Med Res 2021 May;49(5):3000605211014090

Department of Urology, Cancer Hospital of Guangxi Medical University and Guangxi Cancer Research Institute, Nanning, China.

Breast cancer metastasis to the ureter is rare. Fluorine-18-fluorodeoxyglucose positron emission tomography (18F-FDG PET)/computed tomography (CT) is widely used to identify primary lesions of metastatic tumours, however, 18F-FDG PET/CT imaging features of ureteral metastasis from breast cancer are rarely reported.

Ureteral carcinoma metastasizing to the testicle: Can misdiagnosis of orchiepididymitis be avoided?

Urol Ann 2021 Jan-Mar;13(1):86-88. Epub 2021 Jan 19.

Department of Medical Oncology, University Hospital of Ioannina, Ioannina, Greece.

Testicular metastases from ureteral carcinoma are rare and they are generally mimic orchiepididymitis. For this reason, these are associated to misleading diagnoses and cancer treatment delay. We believe that both timing and knowledge of genital blood and lymph reverse flow routes may represent two important parameters for avoiding misleading diagnoses and speed proper anticancer treatment.

Diagnostic ureteroscopy for upper tract urothelial carcinoma: friend or foe?

Arab J Urol 2021 Feb 16;19(1):46-58. Epub 2021 Feb 16.

Urology Department, Fundació Puigvert, Autonomous University of Barcelona, Barcelona, Spain.

Introduction: The European Association of Urology guidelines recommend offering kidney-sparing surgery (KSS) as a primary treatment option to patients with low-risk tumours. Cystoscopy, urinary cytology, and computed tomography urography (CTU) do not always allow correct disease staging and grading, and sometimes there is even a lack of certainty regarding the diagnosis of UTUC. Diagnostic ureteroscopy (d-URS) may therefore be of crucial importance within the diagnostic framework and fundamental in establishing the appropriate therapeutic approach. Read More

Curative-intent Metastasis-directed Therapies for Molecularly-defined Oligorecurrent Prostate Cancer: A Prospective Phase II Trial Testing the Oligometastasis Hypothesis.

Eur Urol 2021 Mar 5. Epub 2021 Mar 5.

University of Toronto, Department of Radiation Oncology, 149 College Street, Unit 504, Toronto, Ontario, M5T 1P5, Canada; Radiation Medicine Program, Princess Margaret Cancer Centre, University Health Network, 700 University Avenue, 7th floor, Toronto, Ontario, M5G 1Z5, Canada; TECHNA Institute, University Health Network, University of Toronto, 200 Elizabeth Street, Toronto, Ontario, M5G 2C4, Canada. Electronic address:

Background: The hypothesis of a curable oligometastatic prostate cancer (PCa) state remains to be clinically-proven. Conventional imaging often fails to localize early recurrences, hampering the potential for radical approaches.

Objective: We hypothesize that prostate-specific membrane antigen (PSMA)-targeted PET-MR/CT allows for earlier detection and localization of oligorecurrent-PCa, unveiling a molecularly-defined state amenable to curative-intent metastasis-directed treatment (MDT). Read More

Department of Respiratory Medicine, Kobe Red Cross Hospital, Kobe, Japan.

Background: Pulmonary lymphangitic carcinomatosis (PLC) is a metastatic lung disease of malignant tumors that spread through pulmonary lymphatic vessels. Although prompt diagnosis and specific treatment of PLC are required due to the poor prognosis associated with this disease, it is often challenging to determine the primary cancer site.

Tumor Location Based Segmentation in Upper-Tract Urothelial Carcinoma Impacts on the Urothelial Recurrence-Free Survival: A Multi-Institutional Database Study.

Curr Urol 2020 Dec 18;14(4):183-190. Epub 2020 Dec 18.

Department of Urology, Osaka Medical College, Takatsuki, Osaka.

Introduction And Objectives: The predictive impact of primary tumor location for patients with upper-tract urothelial carcinoma (UTUC) in the presence of concomitant urothelial bladder cancer, along with urothelial recurrence after the curative treatment is still contentious. We evaluated the association between precise tumor location and concomitant presence of urothelial bladder cancer and urothelial recurrence-free survival in patients with UTUC treated by radical nephroureterectomy with a bladder cuff.

Methods: A total of 1,349 patients with localized UTUC (Ta-4N0M0) from a retrospective multi-institutional cohort were studied. Read More

Laparoscopic abdominal perineal rectal resection for rectal cancer with a horseshoe kidney using preoperative 3D-CT angiography: a case report.

BMC Surg 2021 Jan 6;21(1):15. Epub 2021 Jan 6.

Department of Surgery, Suwa Red Cross Hospital, 5-11-11-50, Kogan-dori, Suwa, Nagano, 392-8510, Japan.

Background: A horseshoe kidney is a congenital malformation involving the fusion of the bilateral kidneys and is often accompanied by anomalies of the ureteropelvic and vascular systems. When performing resection of colorectal cancer in a patient with horseshoe kidney, damage to the ureter or excessive renal arteries should be avoided. To achieve this purpose, comprehensive preoperative anatomical assessments and surgical planning are important. Read More

BJU Int 2021 Jul 5;128(1):112-121. Epub 2021 Jan 5.

Department of Urology, Western Health, Melbourne, Vic., Australia.

Objectives: To describe the Agarwal loop-ligation technique for the management of the distal ureter during laparoscopic radical nephroureterectomy (LRNU) for upper tract urothelial carcinoma (UTUC) and report on long-term oncological outcomes.

Patients And Methods: In the Agarwal loop-ligation technique, the distal ureteric stump is controlled using endoscopic Endoloop or PolyLoop ligation to ensure en bloc excision of the bladder cuff and prevent spillage of upper tract urine into the perivesical space.
