[A CASE OF TESTICULAR TUMOR DIAGNOSED DUE TO ACUTE SCROTUM].

A 32-year-old man visited the emergency department complaining of the right scrotal pain, which occurred suddenly during sexual intercourse. Palpation revealed induration and tenderness on the caudal side of the right testis. Ultrasonography revealed a mosaic-like mass on the caudal side of the testis and no difference in blood flow between the right and left testes.

How does pre-operative antimicrobial treatment influence the intra-operative culture results and infectious complications in patients with positive baseline bladder urine culture undergoing ureteroscopic lithotripsy?

We investigated how pre-operative antimicrobial treatment influenced intra-operative culture (IC) results and infectious complications in patients with positive pre-operative bladder urine culture (PBUC) undergoing ureteroscopic lithotripsy. We assessed 162 patients undergoing ureteroscopic lithotripsy from April 2019 to March 2020. Based on PBUC findings, they were divided into positive and negative PBUC groups.

Chronic Unilateral Hematuria: Compound Papillae Are Likely to Bleed.

The present study investigated the recent outcomes of chronic unilateral hematuria (CUH), focusing on the detailed distribution of bleeding points based on the anatomical classification of the pelvicaliceal system. We evaluated 75 CUH patients treated in the past decade. Bleeding points were recorded separately as five levels of minor calices (Top, Upper, Middle, Lower, and Bottom).

Successful outcomes of endoscopic lithotripsy in completely bedridden patients with symptomatic urinary calculi.

Due to the aging population, the number of completely bedridden individuals is expected to increase, and such individuals are at high risk of developing urinary calculi. This retrospective study included 32 consecutive bedridden patients, who had undergone endoscopic lithotripsy between 2010 and 2019, and aimed to identify the treatment outcomes of endoscopic lithotripsy for bedridden patients. A total of 45 endoscopic lithotripsies were performed to treat stones (median cumulative diameter, 24 mm).

The significance of intraoperative renal pelvic urine and stone cultures for patients at a high risk of post-ureteroscopy systemic inflammatory response syndrome.

We examined the renal pelvic urine culture (RPUC) and stone culture (SC) during ureteroscopy and evaluated their associations with postoperative systemic inflammatory response syndrome (SIRS). We prospectively collected data of 224 patients who underwent ureteroscopic laser lithotripsy from March 2015 to December 2017. We examined the bladder urine culture pre-operatively.

Proposal for a Simple Anatomical Classification of the Pelvicaliceal System for Endoscopic Surgery.

We herein propose a nomenclature for renal calices and anatomical classification of the renal pelvis for endoscopic surgery. We prospectively collected data on a total of 270 patients (540 kidneys) who underwent CT-urography. We then constructed three-dimensional images of the renal pelvis and examined their morphologic classification.

Ureteral Involvement Is Associated with Poor Prognosis in Upper Urinary Tract Urothelial Carcinoma Patients Treated by Nephroureterectomy: A Multicenter Database Study.

Background: The prognostic significance of tumor location for patients with upper urinary tract urothelial carcinoma (UUT-UC) has been disputed. Several papers have reported that ureteral cancer is associated with worse prognosis.

Objective: To investigate the prognostic significance of the presence of ureteral tumors in UUT-UC patients who underwent radical nephroureterectomy (RNU).

Predictive risk factors for systemic inflammatory response syndrome following ureteroscopic laser lithotripsy.

The objective of this study was to investigate risk factors for the development of systemic inflammatory response syndrome following ureteroscopic laser lithotripsy. We retrospectively collected data of 469 patients who underwent ureteroscopic laser lithotripsy at our single institution from February 2008 to June 2016. Details for the patient, the stone, and the surgical factors that potentially contributed to postoperative infection were extracted.

Appropriate kidney stone size for ureteroscopic lithotripsy: When to switch to a percutaneous approach.

Flexible ureteroscopy (fURS) has become a more effective and safer treatment for whole upper urinary tract stones. Percutaneous nephrolithotomy (PNL) is currently the first-line recommended treatment for large kidney stones ≥ 20 mm and it has an excellent stone-free rate for large kidney stones. However, its invasiveness is not negligible considering its major complication rates.

Bimodal pattern of the impact of body mass index on cancer-specific survival of upper urinary tract urothelial carcinoma patients.

Aim: To clarify how body mass index (BMI) affects the risk of death from upper urinary tract urothelial carcinoma (UUTUC) we investigated the impact of BMI on UUTUC using a Japanese multicenter database.

Patients And Methods: Between January 1995 and December 2010, 1,329 patients with upper urinary tract tumors were treated in 13 institutions in Japan. From this group, a cohort of 1,014 patients treated with radical nephroureterectomy was retrospectively reviewed.

Equivalent survival and improved preservation of renal function after distal ureterectomy compared with nephroureterectomy in patients with urothelial carcinoma of the distal ureter: a propensity score-matched multicenter study.

Objectives: To investigate the oncological and functional outcome of distal ureterectomy compared with nephroureterectomy in the management of distal ureteral urothelial carcinoma.

Methods: Using a database including upper urinary tract urothelial carcinoma patients (n = 1329), 282 patients were identified with urothelial carcinoma localized in the distal ureter on clinical evaluation. To adjust for potential baseline differences between groups, 43 patients undergoing distal ureterectomy were matched with 86 patients undergoing nephroureterectomy using propensity scoring.

Risk stratification for bladder recurrence of upper urinary tract urothelial carcinoma after radical nephroureterectomy.

Objectives: To identify risk factors and develop a model for predicting recurrence of upper urinary tract urothelial carcinoma (UTUC) in the bladder in patients without a history of bladder cancer after radical nephroureterectomy (RNU).

Patients And Methods: We retrospectively reviewed 754 patients with UTUC without prior or concurrent bladder cancer or distant metastasis at 13 institutions in Japan. Univariate and multivariate Fine and Gray competing risks proportional hazards models were used to examine the cumulative incidence of bladder recurrence of UTUC.

Single-session ureteroscopy with holmium laser lithotripsy for multiple stones.

Multiple stones are found in 20-25% of patients with urolithiasis. The stone multiplicity is a powerful adverse factor influencing the treatment outcome after shockwave lithotripsy, although guidelines for the treatment of multiple stones have not been well established yet. Herein we report our most recent experience of a single-session ureteroscopy for multiple stones.

Successful outcome of flexible ureteroscopy with holmium laser lithotripsy for renal stones 2 cm or greater.

Although percutaneous nephrolithotomy has been recommended as the first-line treatment for renal stones larger than 2 cm, its major complication rate is not negligible and less invasive approaches are to be explored. Thanks to the recent advances in endoscopic technology, flexible ureteroscopy has become another option in this setting. Herein we report our most recent experience with flexible ureteroscopy for large renal stones.

[Transurethral lithotripsy with rigid and flexible ureteroscopy for renal and ureteral stones: results of the first 100 procedures].

We evaluated the clinical outcome of transurethral lithotripsy (TUL) using rigid & flexible ureteroscopy and holmium : yttrium-aluminum-garnet (YAG) laser in our hospital. We retrospectively reviewed 100 consecutive transurethral lithotripsy procedures performed on 82 patients from May 2008 to June 2010 at our hospital. Twenty-five patients (30%) had multiple stones and 10 patients (12%) had bilateral stones.

Young age as favorable prognostic factor for cancer-specific survival in localized renal cell carcinoma.

Objectives: To evaluate the prognostic effect of age in patients with localized renal cell carcinoma (RCC) and investigate the incidence of Xp11 translocation RCC in young patients who developed recurrence.

Methods: From 1990 to 2007, 2403 Japanese patients underwent nephrectomy for presumed RCC at 9 institutions. Of those, 1143 patients had localized RCC (Stage pT1-2N0M0).

[A case of urachal carcinoma with transverse colon fistula].

A 61-year-old woman was admitted to our hospital because of abdominal pain. Computed tomography showed an abscess in the anterior abdominal wall and an intraabdominal tumor. Biopsy from bladder dome presented adenocarcinoma.

Simple and effective local anesthesia for transperineal extended prostate biopsy: application to three-dimensional 26-core biopsy.

We developed a local anesthetic procedure for three-dimensional 26-core prostate biopsy (3D26PBx), a combination of transperineal 14-core biopsy (TP14PBx) and transrectal 12-core biopsy (TR12PBx). At first, a periapical triangle, confined by the levator ani, the rhabdosphincter and the external anal sphincter muscle, was made visible by transrectal ultrasound. After administration of 1 mL of 1%-lidocaine into the midline perineal skin 1.

Possible role of the RhoC/ROCK pathway in progression of clear cell renal cell carcinoma.

To clarify the role of the Rho small GTP-binding protein (Rho) and its major downstream target, ROCK (Rho-associated serine-threonine protein kinase), in progression of renal cell carcinoma (RCC), we examined mRNA expression for Rho and ROCK genes in surgical specimen of RCC tissues from 78 Japanese patients and in the corresponding non-tumor tissues originating from the same patient using a real-time reverse transcription polymerase chain reaction (RT-PCR). Expression of mRNA for RhoA did not differ between tumor and non-tumor tissues. RhoB mRNA expression was higher in the tumor (P < 0.

Superior vena cava syndrome caused by supraclavicular lymph node metastasis of renal cell carcinoma.

A 65-year-old woman presented with gross hematuria in February 1997. Left renal tumor was revealed and radical nephrectomy was performed. Pathological examination revealed papillary renal cell carcinoma, pT3aN1M1 (ipsilateral adrenal gland).

[A case report: testicular pure seminoma metastasized to costal bone after 2 years post-operatively].

A 32-year-old man underwent orchiectomy for his right testicular tumor (pure seminoma, pT1, stage A(I)). Pelvic and para-aortic lymph nodes were irradiated with 18 Gy as adjuvant therapy. Two years later, he developed low back pain.

Single-blind, randomized controlled study of the clinical and urodynamic effects of an alpha-blocker (naftopidil) and phytotherapy (eviprostat) in the treatment of benign prostatic hyperplasia.
