OBJECTIVE: To explore the clinical features of acute urine retention (AUR) ocurring in patients with benign prostate hyperplasia (BPH). METHODS: Clinical data from 548 patients diagnosed with BPH were retrospectively studied, and the clinical parameters of these patients with or without AUR were analyzed by statistical methods. RESULTS: Development of AUR was found in 164 patients (29.9%). Patients' age, IPSS, maximum flow rate (Q(max)), residual urine volume, prostate volume, transition zone volume, prostate-specific antigen (PSA) density, total PSA (tPSA) and free PSA (fPSA) including the ratio of free to total PSA(f/tPSA) were significantly different in the 2 groups (P<0.05), while there were no significant differences in the disease duration and transition zone index between the 2 groups (P>0.05). Multivariate logistic regression analysis showed that IPSS score, residual urine volume, tPSA, and Q(max) were risk factors for predicting the development of AUR. CONCLUSION BPH patient's age, IPSS, Q(max), residual urine volume, prostate volume, transition zone volume, tPSA and fPSA, and PSA density all influence the occurrence of AUR, in which symptom severity, residual urine volume, total PSA and Q(max) are the principal risk factors for prognosing AUR.

The field of prosthetic urology demonstrates the striking impact that simple devices can have on quality of life. Penile prosthesis and artificial urinary sphincter implantation are the cornerstone procedures on which this specialty focuses. Modern research largely concentrates on decreasing the rates of complication and infection, as the current devices offer superior rates of satisfaction when revision is not necessary. These techniques are also able to salvage sexual function and continence in more difficult patient populations including female-to-male transgender individuals, those with ischemic priapism, and those with erectile dysfunction and incontinence secondary to prostatectomy. This review summarizes modern techniques, outcomes, and complications in the field of prosthetic urology.

OBJECTIVE: Although nerve-sparing radical surgery (NSRS) is an emerging technique for reducing surgery-related dysfunctions, its efficacy is controversial in patients with cervical cancer. Thus, we performed a meta-analysis to compare clinical outcomes, and urinary, anorectal, and sexual dysfunctions between conventional radical surgery (CRS) and NSRS. METHODS: After searching PubMed, Embase, and the Cochrane Library, two randomized controlled trials, seven prospective and eleven retrospective cohort studies were included with 2,253 patients from January 2000 to February 2014. We performed crude analyses and then conducted subgroup analyses according to study design, quality of study, surgical approach, radicality, and adjustment for potential confounding factors. RESULTS: Crude analyses showed decreases in blood loss, hospital stay, frequency of intraoperative complications, length of the resected vagina, duration of postoperative catheterization (DPC), urinary frequency, and abnormal sensation in NSRS, whereas there were no significant differences in other clinical parameters and dysfunctions between CRS and NSRS. In subgroup analyses, operative time was longer (standardized difference in means, 0.948; 95% confidence interval [CI], 0.642 to 1.253), while intraoperative complications were less common (odds ratio, 0.147; 95% CI, 0.035 to 0.621) in NSRS. Furthermore, subgroup analyses showed that DPC was shorter, urinary incontinence or frequency, and constipation were less frequent in NSRS without adverse effects on survival and sexual functions. CONCLUSION: NSRS may not affect prognosis and sexual dysfunctions in patients with cervical cancer, whereas it may decrease intraoperative complications, and urinary and anorectal dysfunctions despite long operative time and short length of the resected vagina when compared with CRS.

PURPOSE: Transrectal ultrasound (TRUS)-guided biopsy of the prostate is usually safe. However, some patients are hospitalized owing to complications from TRUS biopsy. We identified the risk factors for complications and effective preventive measures for treating complications after TRUS biopsy. MATERIALS AND METHODS: Medical records and radiological images of 1,083 patients who underwent TRUS biopsy of the prostate over 10 years in Gyeongsang National University Hospital were examined retrospectively to investigate the correlation between complications after TRUS biopsy and preventive antibiotics, prebiopsy enema, number of biopsy cores, and pathological findings. RESULTS: Complications occurred in 69 patients (6.4%). The complication rates of the 1,008 patients who received antibiotics and the 75 patients who did not were 6.3% and 8.0%, respectively (p=0.469). Complication rates of the pre-biopsy enema group (n=658) and the group without prebiopsy enema (n=425) were 4.7% and 8.9%, respectively (p=0.007). Complication rates of the 6-core biopsy group (n=41) and the 12-core biopsy group (n=955) were 7.3% and 6.3%, respectively (p=0.891). Complication rates of the prostate cancer group (n=306) and the no prostate cancer group (n=713) were 6.2% and 6.6%, respectively (p=0.740). CONCLUSIONS: A prebiopsy enema was associated with a reduced risk of complications after TRUS biopsy. Preventive antibiotics, number of biopsy cores, and pathological findings did not significantly influence the complication rate.

OBJECTIVETo investigate the risk factors of postoperative urinary retention after rectal cancer surgery.

METHODSClinical data of 133 patients with rectal cancer undergoing radical surgery from January 2013 to September 2014 in the General Hospital of the PLA Rocket Force were retrospectively analyzed. Time to the first removal of urinary catheter, incidence of postoperative urinary retention, and time to re-insert indwelling catheter were recorded. Risk factors of urinary retention were analyzed.

RESULTSOf 133 patients, 70 were males and 63 were females, with a median age of 62 (20-79) years old. Distance from tumor lower margin to anal verge were ≤5 cm in 58 patients, >5 cm to 10 cm in 41 patients, and >10 cm to 15 cm in 34 patients. The postoperative TNM stage was recorded in 35 patients with stage I(, 34 with stage II(, 59 with stage III( and 5 with stage IIII(. Surgical procedures included anterior resection (AR) for 92 patients, abdominoperineal resection (APR) for 25 patients and intersphincteric resection (ISR) for 16 patients. Laparoscopic approach was performed in 89 patients compared with open operation in 44 patients. Time to the first removal of urinary catheter was 2-7 days after operation (median, 5 days) and 36 (27.1%) patients developed urinary retention. All the 36 patients achieved spontaneous voiding by re-inserting urinary catheter for 2-28 days (median, 6 days). Univariate analysis showed that elderly (>65 years) and laparoscopic approach had significantly higher incidence of urinary retention [37.5%(21/56) vs. 19.5%(15/77), χ=5.333, P=0.021; 34.8%(31/89) vs. 11.4%(5/44), χ=8.214, P=0.004; respectively]. Multivariate logistic analysis demonstrated that old age(OR=3.949, 95%CI:1.622 to 9.612, P=0.002), laparoscopic approach (OR=5.665, 95%CI:1.908 to 16.822, P=0.002), and abdominoperineal resection (OR=3.443, 95%CI:1.199 to 9.887, P=0.022) were independent risk factors of urinary retention after rectal cancer surgery.

CONCLUSIONSPatients undergoing rectal cancer surgery have a high risk of postoperative urinary retention. More attention should be paid to the old patients, especially those undergoing laparoscopic procedure or abdominoperineal resection, to prevent postoperative urinary retention and urinary dysfunction.
