Objective To develop a clinical nomogram for predicting the probability of bladder outlet obstruction (BOO) in male LUTS/BPH using the most common and noninvasive parameters in clinical practice , with the hope of detecting BOO individually and precisely. Methods Retrospectively analyze the outpatients and inpatients of male LUTS/BPH from November 2003 to November 2015 in Guangzhou First People′s Hospital. Collect the Pressure-flow study parameters and other clinical parameters including Qmax , PV, TZV, TZI, PSA, and PVR. Find out the best independent predictors on the diagnosis of BOO and develop the nomogram for pre-dicting BOO. Results The data from 1 599 patients were analyzed. The areas under the ROC curve (AUCs)of PV, TZV, TZI, PSA, Qmax, and PVR were 0.803, 0.807, 0.698, 0.775, 0.742, and 0.641, respectively. Qmax, PV, and PSA were selected as the best clinical parameters to predict BOO. The Logistic regression equa-tion is Log(p)=0.332 4 - 0.201 8*Qmax + 0.026 6*PV + 1.135 1*PSA. Finally, a nomogram model was developed by R statistical software. This nomogram showed a concordance index of 0.854 according to the inter-nal validation of the model. Conclusions The clinical nomogram presented a high accuracy (85.4%) in de-tecting BOO, which would help predicting BOO in male LUTS/BPH noninvasively, individually, accurately, and providing valuable reference and guidance in clinical decision.

Objective To investigate the application of molecular absorbent recycling system (MARS) in auto liver transplantation (ALT).Methods The clinical data of 46 patients who underwent ALT in Zhongnan Hospital of Wuhan University from September 2014 to August 2015 were retrospectively studied.The patients were randomly divided into the MARS group (n =30) and the hemodialysis group (n =16).In the MARS group,20 patients were male and 10 were female with an average age of (15 ±67) years,and the median age was 46.In the hemodialysis group,8 were male and 8 were female with an average age of (22 ± 54) years.A heparinized left iliac vein was linked to a centrifugal pump of a MARS and an output tube was linked to a left jugular vein.Before the anhepatic phase,physical pretreatment was carried out by ligating the porta hepatis and inferior vena cava (IVC) to adapt the patient to the anhepatic phase.Subsequently,a bypass was established followed by ligation of the IVC.The duration of operation,length of stay in ICU after operation,one-year survival rate and hepatorenal function were studied.Results The duration of operation in the MRAS group and in the hemodialysis group was not significantly different (P ＞0.05).The length of stay in ICU after operation in the MARS group was (12.0 ±3.0) d,which was significantly shorter than that of the hemodialysis group (20.0 ± 2.0) d (P ＜ 0.05).The one-year survival rate in the MARS group was (100％),which was significantly higher than that of the hemodialysis group (93.8％,P ＜0.05).Conclusion The application of MARS in ALT shortened the length of stay in hospital and improved one-year survival rate,resulting in better outcomes than the conventional method.

Objective To evaluate the efficacy and safety of intradetrusor injection of botulinum toxin type A in the treatment of ketamine-related cystitis.Methods A retrospective analysis of clinical data of 36 ketamine-related cystitis patients with intradetrusor injection of botulinum toxin type A treatment in our hospital during August 2010 to December 2015 was conducted, including 31 males and 5 females with a mean age of 25.5 years.All patients had failed to conventional treatment options including cessation of ketamine, antibiotics, M-blockers.At the time of the first injection, patients were injected with 200 U botulinum toxin type A diluted in 15 ml of 0.9％ saline into the detrusor muscle at 30 sites, sparing the trigone, under cystoscopic guidance.3-d voiding diary, interstitial cystitis symptom index (ICSI),interstitial cystitis problem index (ICPI), pelvic pain and urinary frequency/urgency symptom score (PUF) were recorded to evaluate the efficacy.The treatment-related complications were recorded.When the efficacy of botulinum toxin type A decreased and the patient's symptoms returned to baseline before treatment, the patient received repeated injections of botulinum toxin type A with the same dose and method as the first injection.Results Thirty-six patients with ketamine-related cystitis were treated with intradetrusor injection of botulinum toxin type A.Sixteen patients received two injection treatments and two patients received three injection treatments.During the follow-up, 3-d urinary diaries, ICSI, ICPI, and PUF showed a significant improvement in outcome at 4 weeks after the first injection.The efficacy of the second and third injection treatment was also remarkable.Three patients developed urinary tract infection after the first injection, and two patients developed urinary tract infection after the second injection.Mild hematuria occurred in 15 patients after the first injection, and mild hematuria occurred in 7 patients after the second injection, which was improved in 1 to 2 days.All patients did not appear acute urinary retention and other adverse drug reactions.Conclusions Intradetrusor injection of botulinum toxin type A could be a safe and effective method for the treatment of ketamine-related cystitis.Repeated injection therapy is still safe and effective.
