Robot-assisted partial nephrectomy in younger versus older adults with renal cell carcinoma: a propensity score-matched analysis.

Purpose: Our study aimed to compare the surgical outcomes of robot-assisted partial nephrectomy (RAPN) between younger and older patients after adjusting for their background differences. We particularly assessed RAPN outcomes and safety in older patients.

Methods: We retrospectively evaluated 559 patients clinically diagnosed with T1 renal cell carcinoma (RCC) and treated with RAPN between 2013 and 2022 at five institutions in Japan.

[LAPAROSCOPIC LIVE DONOR NEPHRECTOMY WITH HORSESHOE KIDNEY: A CASE REPORT].

We performed laparoscopic live donor nephrectomy (LDN) on approximately 200 patients in Ehime Prefectural Center Hospital between 2003 and 2016. In 2016, a fifty-something woman who was a donor candidate for her husband was revealed to have a horseshoe kidney through contrast-enhanced computed tomography; other LDN procedures used a retroperitoneal approach, but this one used a transperitoneal approach since the latter approach allowed for a more favorable visual field. The left kidney was selected since renal scintigraphy showed equal bilateral renal function and renal arteries are simpler on the left side.

A case of an advanced renal collecting duct carcinoma in which initial therapeutic effect was achieved with pembrolizumab plus axitinib.

Introduction: Renal collecting duct carcinoma is often found in advanced cancers and has a poor prognosis. Here, we present the case of symptomatic metastatic collecting duct carcinoma in which we observed an initial therapeutic effect of immune checkpoint inhibitors plus tyrosine kinase inhibitors.

Case Presentation: The patient was a 69-year-old male who was referred to our hospital for examination of a right chest tumor and related pain.

An obscure case of chronic unilateral hematuria bleeding point.

Chronic unilateral hematuria due to hemangioma of the renal papilla is endoscopically treatable. Hemangiomas of the renal papilla are usually located at the tip of the renal papilla. However in this case, the hemangioma was not located at the tip of the renal papilla, forcing the patient to exercise until just before surgery and to keep the renal pelvic pressure low to identify the hemangioma.

Health-related quality of life in Japanese low-risk prostate cancer patients choosing active surveillance: 3-year follow-up from PRIAS-JAPAN.

Purpose: To evaluate the health-related quality of life (HRQoL) of Japanese men on active surveillance (AS) in the Prostate cancer Research International Active Surveillance study in Japan (PRIAS-JAPAN).

Methods: Participants were included in the PRIAS-JAPAN HRQoL study between January 2010 and March 2016. Their general HRQoL was assessed using a validated Japanese version of the Short-Form 8 Health Survey (SF-8) at enrolment and annually thereafter until discontinuation of AS.

Prospective longitudinal outcomes of quality of life after laparoscopic radical prostatectomy compared with retropubic radical prostatectomy.

Background: There have been few reports on health-related quality of life (HRQOL) after laparoscopic radical prostatectomy (LRP) in Japanese patients. The aim of this study is to assess changes in HRQOL during 36 months after LRP compared with retropubic radical prostatectomy (RRP).

Methods: The subjects were 105 consecutive patients treated with LRP between 2011 and 2012.

Results of second transurethral resection for high-grade T1 bladder cancer.

Background: The aim of this study was to examine the histological outcome and potential therapeutic benefit of second transurethral resection (TUR) for high-grade T1 bladder cancer.

Patients And Methods: The subjects were 171 patients who underwent initial TUR between January 1993 and December 2013, and were diagnosed with high-grade T1 bladder cancer. Second TUR was performed within 4-6 weeks after the initial resection.

Pulmonary metastasectomy from renal cell carcinoma including 3 cases with sarcomatoid component.

Introduction: Usefulness of complete metastasectomy against pulmonary metastases from renal cell carcinoma (RCC) is well known. We examined the efficacy of surgical resection of pulmonary metastases from RCC performed in Shikoku Cancer Center.

Method: Between January 2004 and December 2014, 11 patients with pulmonary metastases from RCC underwent thoracic resection in our institution.

Should inclusion criteria for active surveillance for low-risk prostate cancer be more stringent? From an interim analysis of PRIAS-JAPAN.

Purpose: To define clinical and pathological factors predicting reclassification at the time of 1-year repeat biopsy (re-Bx) based on a Japanese cohort forming part of the Prostate Research International: Active Surveillance (PRIAS) study.

Patients And Methods: The inclusion criteria for the PRIAS study are as follows: clinical stage T1c/T2, PSA ≤ 10 ng/ml, PSA density (PSAD) < 0.2 ng/ml per milliliter, one or two positive biopsy cores, and Gleason score (GS) ≤ 6 at initial diagnostic biopsy.

Health-related quality of life in the first year after laparoscopic radical prostatectomy compared with open radical prostatectomy.

Objective: To assess health-related quality of life in the first year after laparoscopic radical prostatectomy compared with that after open radical prostatectomy.

Methods: The subjects were 105 consecutive patients with localized prostate cancer treated with laparoscopic radical prostatectomy between January 2011 and June 2012. Health-related quality of life was evaluated using the International Prostate Symptom Score, Medical Outcome Study 8-Items Short Form Health Survey (SF-8) and Expanded Prostate Cancer Index Composite at baseline and 1, 3, 6 and 12 months after surgery.

Surveillance biopsy and active treatment during active surveillance for low-risk prostate cancer.

Background: The goals of the study were to examine surveillance biopsy and active treatment in patients under active surveillance (AS) for low-risk prostate cancer and to determine the active treatment-free survival rate.

Methods: The subjects were 87 patients with low-risk prostate cancer who were under AS between 2000 and 2010. The eligibility criteria for AS were T1c, Gleason score ≤ 6, prostate-specific antigen level ≤ 10 ng/ml, one or two positive biopsies, maximum cancer involvement ≤ 50 %, and age ≤ 80 years old.

Correlation between cancer location and oncological outcome after radical prostatectomy.

Objectives: To examine the association between cancer location, resection margins and oncological outcome in patients undergoing radical prostatectomy.

Methods: A total of 505 patients who underwent radical prostatectomy between 1993 and 2009 were included in this analysis. Cancer location, resection margins and pathological factors were assessed based on the 2010 General Rules for Clinical and Pathological Studies on Prostate Cancer.

Health-related quality of life after radical retropubic prostatectomy and permanent prostate brachytherapy: a 3-year follow-up study.

Objectives: To examine quality of life (QOL) for 3 years after radical retropubic prostatectomy (RRP) or permanent prostate brachytherapy (PPB) and to determine differences between the two procedures.

Methods: In all 107 patients who underwent RRP and 91 who received PPB between October 2005 and July 2007 were included in this study. QOL surveys were performed using the international prostate symptom score (IPSS), the Medical Outcome Study 8-items short form health survey and the expanded prostate cancer index composite at baseline and 1, 3, 6, 12 and 36 months after treatment.

Tertiary Gleason pattern 5 and oncological outcomes after radical prostatectomy.

Objectives: This study examined the rate of Gleason pattern 5 and the influence of tertiary Gleason pattern 5 on oncological outcomes.

Methods: Four hundred sixty-six patients underwent a radical prostatectomy between 1993 and 2008. Each surgical specimen was reviewed and assessed for the tumor diameter, Gleason score (which was based on the 2005 International Society of Urological Pathology Consensus Conference criteria) and the percentage of Gleason pattern 5.

Malignant pheochromocytoma with liver metastasis treated by transcatheter arterial chemo-embolization (TACE).

Multiple liver metastatic lesions were shown by computed tomography and scintigraphy with 123I- metaiodobenzylguanidine (MIBG) in a 76-year-old woman 2 years after resection of a pheochromocytoma of the right adrenal gland. Transcatheter arterial chemo-embolization (TACE) was performed for the liver metastasis, with blood pressure strictly controlled by administration of doxazosin and phentolamine for the prevention of hypertensive crisis after TACE. There were no severe adverse events associated with the treatment, and the number and size of the lesions were decreased.
