INTRODUCTIONThe objective of this study is to determine the relationships between prostatic volume (PV) and intravesical prostatic protrusion (IPP) with benign prostatic obstruction (BPO).
MATERIALS AND METHODSA total of 408 males (aged 50 years and above) who presented with lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH) were recruited. All had International Prostate Symptoms Score (IPSS), quality of life (QOL) index, uroflowmetry (Qmax) and postvoid residual urine (PVR) measured by transabdominal ultrasonography (TAUS). The PV and the degree of IPP were also measured by TAUS in the transverse and sagittal planes respectively. The PV is classified as Grade a, (20 ml or less), Grade b, (more than 20 ml to 40 ml) and Grade c, (more than 40 ml), while the IPP is graded as Grade 1 (5 mm or less), Grade 2 (more than 5 mm to 10 mm) and Grade 3 (more than 10 mm).
RESULTSThere was a fair positive correlation between the PV and IPP (Spearman, r(s) = 0.62, P <0.001) with important clinical exceptions. There was negative correlation between the PV and Qmax (rs = -0.20, P = 0.022), IPP and Qmax (r(s) = -0.30, P <0.001). PV and IPP were good predictors of BPO. However, IPP was slightly better (r(s) of -0.30 vs -0.20) than PV.
CONCLUSIONPV is related to IPP with important clinical exceptions. IPP is a better predictor of BPO than PV.

OBJECTIVE: The purpose of this study was to compare the effectiveness of MR urography (MRU) with that of ultrasonography (US) in the evaluation of urinary tract when this failed to opacify during excretory urography (EXU). MATERIALS AND METHODS: Twelve urinary tracts in 11 patients were studied. In each case, during EXU, the urinary system failed to opacify within one hour of the injection of contrast media, and US revealed dilatation of the pelvocalyceal syytem. Patients underwent MRU, using a HASTE sequence with the breath-hold technique; multi-slice acquisition was then performed, and the images were reconstructed using maximal intensity projection. Each set of images was evaluated by three radiologists to determine the presence, level, and cause of urinary tract obstruction. RESULTS: Obstruction was present in all twelve cases, and in all of these, MRU accurately demonstrated its level. In this respect, however, US was successful in only ten. The cause of obstruction was determined by MRU in eight cases, but by US in only six. In all of these six, MRU also successfully demonstrated the cause. CONCLUSION: MRU is an effective modality for evaluation of the urinary tract when this fails to opacify during EXU, and appears to be superior to US in demon-strating the level and cause of obstruction.

OBJECTIVETo analyze the clinical features, renal damage and prognosis of primary vesicoureteric reflux (VUR) in children, hoping to give more attention to early recognition and treatment of the disease.
METHODSBetween June 1995 and December 2006, 974 patient were admitted in our hospital because of urinary tract infection (UTI), 139 primary VUR children were enrolled in the retrospective study. VUR grades, renal scar development, renal ultrasound and urinalysis were evaluated.
RESULTSThe incidence of VUR in UTI children was 14.3% (139/974), however, the incidence in infants and toddlers (younger than two years of age) was 17.2% (79/458), which was greatly higher than that in school children. Of the 139 children, 79(56.8%) were younger than two years and the number of boys was much larger than that of girls (P = 0.001). Bilateral reflux was found in 69 cases, unilateral in 70 cases; the percentages of mild reflux (grade I-II) was 19.7% (41/208), moderate reflux (grade III) was 35.6% (74/208), severe reflux (grade IV-V) was 44.7% (93/208). Dimercaptosuccinic acid (DMSA) scanning was performed for 135 patients, and renal scar was found in 37% (50/135), and the rate of scar in infants was the highest (42.4%), and 30 (60%) patients with renal scar were younger than two years of age. Among them five patients were found to have renal scar during the follow up period, four of them were younger than two years. The rate of renal scar in moderate and severe reflux was much higher than that in mild reflux cases, the risk of occurring renal scar would increase with its severity of reflux (P < 0.001). The sensitivity and specificity of renal ultrasound in suggesting VUR were 24.8% and 94.3%, respectively. The positive outcome of urinary N-acetyl-beta-glucosaminidase was a bit high, but there were no associations between renal scar and urinary microprotein (P > 0.05). Thirty-one cases were followed up for long time (> 1 year); and 90% of urinary infection was controlled and in 44.4% of patients VUR disappeared with medical treatment. No child had decreasing renal function in follow-up period.
CONCLUSIONChildren with primary VUR need early diagnosis and treatment. Insisting on normal therapy and long-term follow-up will protect renal function effectively.

OBJECTIVETo compare the positive rates and complications of ultrasound-guided transrectal and transperineal prostate biopsies.
METHODSWe retrospectively analyzed 156 cases of ultrasound-guided transrectal (n = 97) and transperineal (n = 59) prostate biopsy, and compared the positive rate and post-biopsy complications between the two approaches.
RESULTSThe positive rates in the transrectal and transperineal groups were 48.4% and 44.1%, respectively, with no significant difference between the two approaches according to different PSA levels (P >0.05). No statistically significant differences were observed between the transrectal and transperineal groups in the post-biopsy incidence rates of such complications as hematuria (54.6% vs 42.4%, P >0.05), lower urinary tract symptoms (17.5% vs 22.0%, P >0.05), dysuria (9.3% vs 6.8%, P >0.05), and acute urinary retention (7.2% vs 6.8%, P >0.05). However, the incidence rates of post-biopsy infection and rectal bleeding were remarkably higher (15.5% vs 3.4%, P<0.05 and 50.5% vs 3.4%, P >0.01) while that of perineal swelling markedly lower in the former than in the latter (3.1% vs 13.6%, P <0.05).
CONCLUSIONTransrectal and transperineal biopsies are both effective for the diagnosis of prostate cancer. Since their complications vary, the choice between the two methods depends on the specific condition of the patient.

Objective:
To investigate the effects of transrectal ultrasound conductance (TRUSC)-guided administration of traditional Chinese medicine on histological prostatitis in men with small-size BPH and low urinary tract symptoms (LUTS) after transurethral resection of the prostate (TURP).
METHODS:
This study included 167 BPH patients without surgical contraindications. We randomized the patients into an experimental group (n = 84) and a control group (n = 83), with no statistically significant differences between the two groups in age, prostate volume, International Prostate Symptom Score (IPSS), and quality of life (QoL) (P >0.05). The patients of the experimental group received TRUSC-guided administration of traditional Chinese medicine, qd, for 7 days before TURP, while those of the control group underwent TURP only. After treatment, we compared the results of postoperative pathological examination of the prostate tissue, the histological grade of inflammation, IPSS, and QoL scores between the two groups of patients.
RESULTS:
In the experimental group, there were 12 cases of non-inflammation (14.3%), 43 cases of mild inflammation (51.2%), 28 cases of moderate inflammation (33.3%), and 1 case of severe inflammation (1.2%), as compared with 8 cases of non-inflammation (9.6%), 28 cases of mild inflammation (33.7%), 45 cases of moderate inflammation (51.8%), and 2 cases of severe inflammation (2.4%) in the control group (P <0.05). Compared with the baseline, both the experimental and control groups showed significant improvement at 4 weeks after surgery in IPSS (22.20±4.14 vs 4.26±2.64 and 23.05±4.11 vs 7.02±4.15, P <0.05) and QoL scores (4.33±0.83 vs 1.25±1.64 and 4.25±0.91 vs 2.05±1.95, P <0.05).
CONCLUSIONS
TRUSC-guided administration of traditional Chinese medicine can significantly alleviate histological inflammation and improve QoL in men with small-size BPH and LUTS after TURP.

Objective:
To explore the feasibility and effectiveness of "one-puncture one-needle" transrectal ultrasound (TRUS)-guided prostate biopsy in the prevention of postoperative infections.
METHODS:
We retrospectively analyzed the clinical data about "one-puncture one-needle" (the observation group) and "one-person one-needle" (the control group) TRUS-guided prostate biopsy performed in the Second People's Hospital of Guangdong Province from January 2005 to December 2015, and compared the incidence rates of puncture-related infection between the two strategies. By "one-puncture one-needle", one needle was used for one biopsy puncture, while by "one-person one-needle", one needle was used for all biopsy punctures in one patient and the needle was sterilized with iodophor after each puncture.
RESULTS:
Totally, 120 patients received 6+1-core or 12+1-core "one-person one-needle" and 466 underwent 12+1-core "one-puncture one-needle" TRUS-guided prostate biopsy. There were no statistically significant differences between the two groups of patients in age, the prostate volume, the serum PSA level, or the detection rate of prostate cancer (P >0.05). Compared with the control group, the observation group showed remarkably lower incidence rates of puncture-related urinary tract infection (7.5% vs 0.9%, P <0.05), fever (5.0% vs 1.1%, P <0.05), bacteriuria (2.5% vs 0.2%, P <0.05), and total infections (16.7% vs 2.6%, P<0.05) postoperatively. Two cases of bacteremia or sepsis were found in each of the groups, with no significant difference between the two.
CONCLUSIONS
"One-puncture one-needle" TRUS-guided prostate biopsy can effectively prevent puncture-related infections.

PURPOSE: Complications after prostate biopsy have increased and various causes have been reported. Growing evidence of increasing quinolone resistance is of particular concern. In the current retrospective study, we evaluated the incidence of infectious complications after prostate biopsy and identified the risk factors. MATERIALS AND METHODS: The study population included 1,195 patients who underwent a prostate biopsy between January 2007 and December 2012 at Chung-Ang University Hospital. Cases of febrile UTI that occurred within 7 days were investigated. Clinical information included age, prostate-specific antigen, prostate volume, hypertension, diabetes, body mass index, and biopsy done in the quinolone-resistance era. Patients received quinolone (250 mg intravenously) before and after the procedure, and quinolone (250 mg) was orally administered twice daily for 3 days. We used univariate and multivariate analysis to investigate the predictive factors for febrile UTI. RESULTS: Febrile UTI developed in 39 cases (3.1%). Core numbers increased from 2007 (8 cores) to 2012 (12 cores) and quinolone-resistant bacteria began to appear in 2010 (quinolone-resistance era). In the univariate analysis, core number> or =12 (p=0.024), body mass index (BMI)>25 kg/m2 (p=0.004), and biopsy done in the quinolone-resistance era (p=0.014) were significant factors. However, in the multivariate analysis adjusted for core number, the results were not significant, with the exception of BMI>25 kg/m2 (p=0.011) and biopsy during the quinolone-resistance era (p=0.035), which were significantly associated with febrile UTI. CONCLUSIONS: Quinolone resistance is the main cause of postbiopsy infections in our center. We suggest that further evaluation is required to validate similar trends. Novel strategies to find alternative prophylactic agents are also necessary.
