OBJECTIVE: To analyze the common hemorrhage sites during laparoscopic rectal cancer surgery in order to take reasonable prevention and management. METHODS: Clinical data of 355 rectal cancer patients who underwent laparoscopic total mesorectal excision in Shanxi Provincial People's Hospital from January 2012 to December 2014 were retrospectively analyzed. Common bleeding sites, blood loss, and hemostasis time were recorded. According to the date of operation, patients were divided into 2012 group (91 cases), 2013 group (122 cases) and 2014 group(142 cases)...

INTRODUCTION: Elevated plasma homocysteine (Hcy) levels have been associated with several tissue injuries including heart and liver fibrosis. In these diseases, hyperhomocysteinemia (Hhcy) plays a major role in modulating the alteration of the balance between matrix metalloproteinases (MMP) and tissue inhibitors of metalloproteinases (TIMPs), leading to the pathological accumulation of extracellular matrix (ECM) proteins. Since the effect of Hhcy on ECM of seminal vesicle was not studied, the aim of our research was to check if Hcy can induce a remodeling within seminal vesicles ECM...

OBJECTIVE: The aim of this study was to construct a stratification model based on early postoperative kinetics of prostate-specific antigen (PSA) to select the most suitable high-risk patients for early intervention after radical prostatectomy (RP). MATERIALS AND METHODS: The study evaluated 205 men who had undergone RP without any adjuvant treatment. All of the patients had positive surgical margins, extracapsular extension and/or seminal vesicle invasion. The patients underwent multiple ultrasensitive PSA measurements on days 14, 30, 60 and 90 after RP, and subsequently at 3 month intervals...

OBJECTIVES: Inclusion of 3-dimensional H magnetic resonance spectroscopic imaging (3D-H-MRSI) in routine multiparametric MRI of the prostate requires good quality spectra and easy interpretable metabolite maps of the whole organ obtained without endorectal coil in clinically feasible acquisition times. We evaluated if a semi-LASER pulse sequence with gradient offset independent adiabaticity refocusing pulses (GOIA-sLASER) for volume selection can meet these requirements. MATERIALS AND METHODS: Thirteen patients with suspicion of prostate cancer and 1 patient known to have prostate cancer were examined at 3 T with a multichannel body-receive coil...

Parasitic castration is an adaptive strategy where parasites usurp the hosts' reproductive physiology to complete their life cycle. The alterations in the host traits vary in their magnitude, from subtle changes in the host morpho-physiology and behaviour to the production of complex aberrant phenotypes, which often depend on the host gender. The strepsipteran macroparasite Xenos vesparum induces dramatic behavioural and physiological changes in its female host, the paper wasp Polistes dominula, while its effect on the male phenotype is largely unknown...

The paraoxonase type 1 (PON1) is an enzyme with antioxidant properties recently identified in the seminal plasma (SP) of several species, including the porcine. The aims of the present study were to (1) describe the inmunohistochemical localization of PON1 in the genital organs of fertile boars and (2) evaluate the relationship among PON1 activity and high-density lipoprotein cholesterol (HDL-C) concentration in fluids of the boar genital organs. Immunohistochemical analysis demonstrated that PON1 was present in testis (specifically in Leydig cells, blood vessels, spermatogonia and elongated spermatids), epididymis (specifically in the cytoplasm of the principal epithelial cells, luminal secretion and in the surrounding smooth muscle) and the lining epithelia of the accessory sexual glands (cytoplasmic location in the prostate and membranous in the seminal vesicle and bulbourethral glands)...

The clinical significance of mucinous prostatic adenocarcinoma remains uncertain. From 6440 cases of prostatic adenocarcinoma treated by radical prostatectomy and reported by Aquesta Uropathology from 2009 to 2014, mucinous components of 5-100% were found in 143 (2.2%). The mean age was 61.4 years, mean preoperative serum was PSA 7.8 ng/mL and clinical stage category was cT1 in 81% and cT2 in 19% of cases. Cases were graded using the 2014 International Society of Urological Pathology recommendation of grading the underlying architecture and Gleason scores were 3+4 in 13...

PURPOSE: PET/CT using (68)Ga-labelled prostate-specific membrane antigen PSMA-11 (HBEDD-CC) has emerged as a promising imaging method in the diagnostic evaluation of prostate cancer (PC) patients with biochemical recurrence. However, assessment of local recurrence (LR) may be limited by intense physiologic tracer accumulation in the urinary bladder on whole-body scans, normally conducted 60 min post-tracer injection (p.i.). It could be shown on early dynamic imaging studies that (68)Ga-PSMA-11 uptake in PC lesions occurs earlier than tracer accumulation in the urinary bladder...

A 34-year-old male presented with an 8-month history of passing increasingly painful 'grit' in his ejaculate. Semen analysis was normal as were urinary and blood tests. T1-weighted MRI revealed several bilateral high-signal areas measuring up to 1 cm in diameter, located in the seminal vesicles. These were confirmed as calculi on T2-weighted imaging and a seminal vesiculogram, with no drainage from the left ejaculatory duct and only minimal from the right duct. He is currently awaiting a robot-assisted laparoscopic vesiculotomy after completion of family...

We treated a 64-year-old man for rectal cancer with direct invasion to the seminal vesicles and no distant metastases by complete resection with laparoscopy and transanal minimally invasive surgery (TAMIS). We inserted the TAMIS device into the anal canal to above the anorectal ring and dissected to prostate level. High ligation of the inferior mesenteric artery and vein was performed by standard medial laparoscopy. The sigmoid and descending colon were mobilized, and in the postrectal space, we dissected to the space made by TAMIS...

Hematospermia or hemospermia is defined as the presence of blood in ejaculate. The true prevalence of the condition is unknown because many cases escape the patient's notice, and remain unrecognized and unreported. There are two main aims in the patient evaluation: first, to ensure that there is no specific condition that is treatable; second, to reassure the patient's parents that no causative factor is present. Many physicians are unfamiliar with this disorder and this forms the basis for our current review...
