RESUMEN
Schistosomiasis cystitis is a urogenital system disease caused by Schistosoma aegypt. Common clinical manifestations are frequent urination, urgency, dysuria, and terminal hematuria, but new infections can be asymptomatic. Detection of parasite eggs by urine microscopy is considered to be the gold standard for diagnosis, but the result may be a false negative in the inactive period. The main epidemic of this disease is located in Africa and the Middle East area. However, in china, there are few reports of confirmed cases. This article reports a case of imported schistosomiasis cystitis. The patient is a Sudanese, male, who has been studying in China for more than 2 years, mainly with persistent painless hematuria for more than 6 months. Cystoscopy was proposed to diagnose a bladder mass, and schistosomiasis cystitis was confirmed by pathological diagnosis after surgery.
RESUMEN
【Objective】 To evaluate the efficacy and safety of different doses and frequencies of oral Sildenafil in the treatment of erectile dysfunction (ED). 【Methods】 The randomized,open clinical trial included 120 ED patients who met the inclusion and exclusion criteria. The patients were randomly divided into the following groups:on-schedule (25 mg/day),on-demand (50 mg,taken irregularly half an hour before each sexual life),new regular group (25 mg/day,50 mg more before each sexual life),regular group (100 mg/time,twice/week). All treatments lasted for 8 weeks. The follow-up indexes included the five-item International Index of Erectile Function (IIEF-5),Erection Hardness Scale (EHS) and Sexual Encounter Profile (SEP2/3). The adverse reactions were recorded. 【Results】 The IIEF-5 scores of the four groups were significantly higher than those after baseline treatment (P0.05). In terms of effective rate,at the 16th week,there were significant differences between the on-demand group (10.7%) and new regular group (62.1%),and between the on-demand group (10.7%) and regular group (50.0%) (P<0.001). In terms of EHS, the percentage of grade 4 patients in regular group was significant higher than that in the on-demand group at the 8th week and 16th week (all P<0.05). In terms of positive rate of SEP-3,there was a significant difference between the on-demand group and regular group (P=0.042) at the 16th week. In the course of treatment,there were transient adverse reactions such as headache,blurred vision,stuffy nose and back pain,which did not affect the treatment. 【Conclusion】 All of the four treatment methods of oral sildenafil showed good efficacy. Both regular group and new regular group maintained good clinical efficacy during the follow-up,which is better than that of the on-demand group. The new regular scheme can be used as a new,safe and effective treatment option.

Objective:To investigate the efficacy and safety of black tomato concentrated sauce in the treatment of benign prostatic hyperplasia(BPH) with lower urinary tract symptoms(LUTS).Methods:An open, randomized and controlled trial was conducted, and 150 BPH patients with LUTS were randomly assigned to three groups: experimental group(60 cases), placebo group (45 cases) and positive control group(45 cases) in the Department of Urology, Lanzhou University Second Hospital from December 2018 to September 2020.Inclusion criteria: age≥50 years old; first diagnosis of BPH, or interrupted medical treatment of BPH for more than 1 month; maximum urinary flow rate (Q max) <15ml/s; prostate volume (PV)≥20ml; IPSS≥8, QOL≥2. Exclusion criteria: lower urinary tract obstruction not caused by BPH, post-void residual urine volume(PVR) >250 ml; history of acute urinary retention in the last 3 months; prostate nodules and suspected prostate cancer were revealed by digital rectal examination and transrectal B-ultrasoundor; prostate-specific antigen (PSA)≥10 ng/ml; neurogenic bladder, perivous history of bladder, prostate, or urethra operations; suffering from serious heart, lung, liver, kidney and other diseases. The patients in the experimental group were orally treated with black tomato concentrated sauce(30 g/once, 3 times/day). The patients in the placebo group were orally administrated with placebo. In the positive control group, the patients with PV≤30ml were orally treated with tamsulosin(0.2mg/once, 1 time/day), the patients with PV>30ml were orally administrated with tamsulosin and finasteride(5 mg/once, 1 time/day). All enrolled patients were treated for 3 months. At the end of third month, the IPSS, QOL, PV, PVR, Q max, average urinary flow rate(Q ave), total PSA(tPSA), free PSA (fPSA), testosterone(TST) and the incidence of adverse reaction were assessed. Results:128 of 150 cases, including 52 cases in experimental group, 36 cases in placebo group and 40 cases in positive control group, completed the study, the rest was excluded due to not take medication regularly and fail to follow-up. There were no significant differences in baseline parameters among experimental group, placebo group and positive control group ( P>0.05) in age[(63.21±8.61) vs.(62.36±6.32) vs. (63.94±7.78)years old], body mass index[(23.74±3.17) vs. (23.94±3.09) vs. (24.26±2.91)kg/m 2], IPSS[(17.5±6.6) vs. (15.4±5.8) vs. (17.9±6.8)], QOL[4.0(3.0, 4.0) vs. 4.0(3.0, 4.5) vs. 4.0(3.0, 5.0)], Q max [(8.60±3.04) vs. (9.13±2.92) vs. (9.58±3.26) ml/s], Q ave[(4.39±1.69) vs. (4.66±1.76) vs. (4.88±1.60)ml/s], PV [32.00(25.55, 45.40)vs. 30.00(24.45, 38.35)vs. 34.80(27.65, 56.65)ml], PVR[23.50(8.25, 45.75) vs.5.50(0, 47.75) vs. 29.00(0, 84.00)ml], tPSA [1.53(0.89, 3.00) vs. 1.23(0.69, 1.98) vs. 2.23(0.90, 4.15)ng/ml], fPSA [0.37(0.28, 0.76) vs. 0.37(0.22, 0.52) vs. 0.54(0.30, 0.97) ng/ml] and TST[(443.64±156.32) vs. (493.97±176.16) vs. (450.89±135.08)ng/dl]. After 3 months of treatment, the IPSS in experimental group was(9.9±5.7), QOL score 2.0(2.0, 3.0), Q max(11.78±5.24)ml/s, Q ave(5.86±3.00)ml/s, tPSA 1.64(0.96, 3.32)ng/ml and TST (475.91±177.33)ng/dl, which were significantly different compared with pre-treatment( P<0.05). In positive control group, IPSS was (9.0±6.2), QOL 2.0(2.0, 3.0), Q max(11.73±4.50)ml/s, Q ave(6.11±2.53)ml/s, tPSA 1.57(0.80, 3.09)ng/ml, fPSA 0.37(0.24, 0.63)ng/ml and TST (526.11±126.88)ng/dl, which were statistically different compared with pre-treatment( P<0.01). However, there were no significant differences in all the above indexes in placebo control group compared with the baseline( P>0.05). The numerical changes of IPSS, QOL, Q maxand Q ave between experimental group and placebo group had statistically significant differences ( P<0.05). The changes of IPSS, QOL, Q max, Q ave, PV, tPSA, fPSA and TST between positive control group and placebo group had significant differences ( P<0.05). The changes of PV, tPSA and fPSA between positive control group and experimental group had statistically significant differences ( P<0.05). The incidence of adverse reactions was 5.77% (3/52, including 1 headache and 2 stomach discomfort) in experimental group, 5.56% (2/36, including 1 headache and 1 stomach discomfort) in placebo group, and 10.00%(4/40, including 1 dizzy, 1 nasal obstruction and 2 erectile dysfunction) in positive control group. And there was no statistical difference in the incidence of adverse reactions among three groups ( P>0.05). Conclusions:Black tomato concentrated sauce shows an excellent effect on patients with LUTS/BPH, and improves the quality of life with few adverse events.
RESUMEN
Testicular torsion is one of the most common scrotal emergencies in urology, which often requires emergency surgery to preserve the turned testicle. There are many studies suggest that testis still has ischemia-reperfusion injury after detorsion, which will threaten the sex hormone levels and fertility of patients. This paper reviewed the research progress of testicular torsion in order to improve clinicians’ understanding of testicular torsion.
RESUMEN
Objective To investigate the effect of the endoscopic surveillance system in irrigating fluid absorption and bleeding during transurethral resection of the prostate.Methods In vitro trials,we simulated the fluid absorption and bleeding in the operation by using self-developed endoscopic surveillance system from January 2013 to June 2013.Continuous irrigation of 5 ％ mannitol solution,we extracted 5 times irrigating fluid (each time 100 ml and a total of 500 ml) in the process of irrigation and recorded absorption measurements of every time extraction rinses.At the same time,we dripped human whole blood 5 times(each time 5 ml and a total of 25 ml) in the process of irrigation and recorded the bleeding measurements.The above process was repeated three times to detect the accuracy and consistency of the endoscopic surveillance system.In clinical trials,50 cases of BPH were monitored in surgery and the biochemical index,hemodynamics,irrigating fluid absorption and bleeding were compared from October 2016 to April 2017.The included criteria contained as follow:the age of patients should be more than 50 years.The transabdominal ultrasound showed that the volume of prostate should be more than 60 ml.The maximal uroflowmetry should be less than 15ml/s.The IPSS scores should be more than 8.Based on the operative time,two groups (＜60 min and ≥ 60 min) were classified.Results We developed the endoscopic surveillance system which is original in the world.In vitro trials,the average irrigating fluid were (100.60 ± 2.07) ml,(201.00±3.39) ml,(302.00±4.67) ml,(403.60±4.39) ml and (502.40 ±7.57) ml;and the average bleeding were (5.06 ± 0.11) ml,(10.10 ± 0.16) ml,(15.04 ± 0.15) ml,(20.06 ± 0.11) ml and (25.10 ± 0.16) ml.No significant difference was observed in all groups (P ＞ 0.05).In clinical trials,we compared some preoperative and postoperative indexes.The average blood oxygen saturation were (94.46 ± 2.49) ％ and (92.39 ± 2.77) ％ (P ＜ 0.01),the average Serum sodium ion concentration were (141.05 ± 2.52) mmol/L and (138.06 ± 4.27) mmol/L(P ＜ 0.01),the average HGB were (143.50 ± 13.43) g/L and (137.04 ± 14.25) g/L(P ＜ 0.01).The average HCT were (42.05 ± 4.09) ％ and (137.04 ± 14.25) ％ (P ＜ 0.01).The average HR were (77.9 ± 7.6) beats per minute and (77.93 ± 6.93) beats per minute (P＞0.05).The MAP were (90.32 ± 9.75) mmHg and (91.07±8.96)mmHg(P＞0.05).The average serum potassium ion concentration were (4.13 ± 0.53) mmol/L and (4.09 ± 0.37) mmol/L (P ＞ 0.05).The average irrigating fluid absorption of the group less than 60 minutes and the group equal or more than 60 minutes were (401.83 ± 279.23) ml and (885.25 ± 367.68) ml (P ＜ 0.01).The average blood loss were (64.10 ±47.47) ml and (158.40 ± 65.22) ml(P ＜0.01).The preoperative and postoperative hemodynamic,blood biochemical and hematology showed difference in our trials.Irrigating fluid absorption and blood loss were positively associated with operation time.Conclusions The endoscopic surveillance system was safety and accuracy.It can offer real-time monitoring data and alarm mechanism for the surgeons that possibly improve operation safety.
