Introduction Page kidney causes secondary hypertension due to external compression of the renal parenchyma and hypoperfusion. Case presentation A 21‐year‐old healthy man was diagnosed with during a medical examination 3 months after he had gotten bruise at right lumbar region. The patient's blood pressure 176/120 mmHg. Computed tomography showed large encapsulated cystic lesion around severe parenchyma. Dimercaptosuccinic acid scintigraphy revealed decreased split function. Therefore,...

These 2024 guidelines address male infertility amid Japan's declining birth rate, following the recent provision of national health insurance coverage for treatments. Male factors contribute to approximately 50% cases, with spermatogenic dysfunction being most common cause (82.4%). The provide evidence-based recommendations diagnosing and treating infertility. Diagnostic approaches include comprehensive medical history, physical examination, semen analysis, hormone testing, genetic testing...

Melamine was recently identified as a risk factor for renal calculi following the milk powder contamination in China. However, long-term natural history of melamine exposure and its effects remain unknown. We evaluated function other adverse health using rat model administered cyanuric aid, considering age sex. Twelve male F334/N rats each ages 6, 10, 26 weeks (N = 36) were equally assigned to Group M + C or controls. 12 mg · kg-1 day-1 acid 28 days. Serum urine samples kidney sections on...

To determine the effect of prostate weight on preoperative and postoperative outcomes robotic-assisted laparoscopic radical prostatectomy with a posterior approach to seminal vesicle. This retrospective study examined prospectively collected data 219 prostatectomies performed from May 2011 February 2013. Patients were divided into four groups based pathologic weight: <30 g, 30–49 50–79 ≥80 g. Continence sexual function assessed using validated questionnaires. Of patients, 19, 143, 51, 6 had...

In cryptorchidism, germ cell development failure presents from infancy and may be reflected by altered hormonal levels produced Sertoli cells. Our object was to assess for associations between serum hormone testicular histopathology in cryptorchidism with an infertility risk according the pretreatment undescended positions.Prepubertal cryptorchid boys aged 7-91 (median 20) months who underwent orchidopexy 2014 2019 were included (122 unilateral [median 19 {range 7-91}], 23 bilateral [24...

We examined changes in the serum testosterone level and sperm testis epididymis by using tail-suspended mice, which are a simulation model of body fluid shift space, to evaluate possibility spermatogenesis failure space environment. also studied pathological disorders mice. Tail suspension was imposed with tail harness degree at hindlegs mice did not touch floor housing unit. In control similarly fixed impose same stress, except that hindleg remained on floor. Body weight significantly...

Summary Obesity is reported to have adverse effects on semen quality and the endocrine system. In this study, we evaluated effect of obesity sperm retrieval outcome reproductive hormone levels in Japanese men with non‐obstructive azoospermia ( NOA ). This study based clinical records 217 [172 a 46, XY karyotype, 45 Klinefelter syndrome KS )] who underwent microdissection testicular extraction at Nagoya City University Hospital between January 2004 December 2014. Body mass index BMI ) serum...

Some preoperative factors affecting the outcome of microdissection testicular sperm extraction (micro-TESE) have been previously evaluated. However, other than Klinefelter syndrome (KS), no chromosomal anomalies discussed in context retrieval outcomes. The objective this study was to describe and their relationship with outcomes patients non-obstructive azoospermia (NOA). Of 197 NOA whose clinical records were retrospectively reviewed, 144 (73.1%) had normal 46,XY karyotype, 40 (20.3%) KS...

Objectives To experimentally evaluate the clinical application of N ‐methyl‐4‐isoleucine cyclosporin, a novel selective inhibitor cyclophilin D activation. Methods In vitro, cultured renal tubular cells were exposed to calcium oxalate monohydrate crystals and treated with cyclosporin. The mitochondrial membrane was stained tetramethylrhodamine ethyl ester perchlorate observed. vivo , S prague– awley rats divided into four groups: control group, an ethylene glycol group (administration induce...

The patient was a 9-year-old premenarcheal pediatric female, whose chief complaint well-circumscribed palpable right breast mass without nipple discharge. Although the had noticed lump 2 years prior to hospital admission, its size (1.5 × 1.3 cm) been stable. There no family history or previous of malignancies. Physical examination showed well-delimited, elastic-firm and movable tumor just beneath areolar complex. Regional lymph nodes were not palpable. Ultrasonography computed tomography...

Objectives To compare the surgical outcomes of laparoscopic radical prostatectomy and robot‐assisted prostatectomy, including frequency location positive margins. Methods The study cohort comprised 708 consecutive male patients with clinically localized prostate cancer who underwent ( n = 551) or 157) between J anuary 1999 S eptember 2012. Operative time, estimated blood loss, complications, margins were compared prostatectomy. Results There no significant differences in age body mass index...

Robot-assisted radical prostatectomy (RARP) is commonly performed using the transperitoneal (TP) approach with six trocars over an 8-cm distance in steep Trendelenburg position. In this study, we investigated feasibility and benefit of extraperitoneal (EP) a 4-cm flat or 5° We also introduced four new steps to surgical procedure compared results complications between EP TP propensity score matching. Between August 2012 2016, 200 consecutive patients without any physical restrictions...

The role of cyclooxygenases (COX) in the male reproductive organ remains unclear. However, there are some reports suggesting that COX-2 might have an effect on spermatogenesis or steroidogenesis. In this study, we examined whether was induced impaired testes, and also investigated possible COX testes using experimental cryptorchidism model mice. Five-week-old mice underwent operation to induce unilateral via abdominal incision suturing left lateral wall, they were then divided into 3 groups:...

Background and Aims: We carried out clinostat parabolic flight experiments to examine the effects of a microgravity (µG) environment on human sperm motility. Methods: Semen samples were obtained manually from 18 healthy men (aged 27.4 ± 5.4 years) who had given their informed consent. In experiments, that left stationary used as control. Samples rotated vertically horizontally rotation control rotation, respectively. using jet plane, motility was compared for each parameter at µG, 1G 2G. The...
