| 1 | Does urodynamics predict voiding after benign prostatic hyperplasia surgery in patients with detrusor underactivity?显示文摘Objective:We sought to determine if urodynamic study(UDS)predicted voiding outcomes in men with detrusor underactivity(DU)and benign prostatic enlargement(BPE)who underwent photovaporization of the prostate(PVP).Methods:Between September 2010 and July 2015,106 male patients with BPE and DU were identified.All patients underwent PVP.Urinary retention was noted by the preoperative necessity for an indwelling or intermittent catheter.Data collection included comorbidities,quality of life(QoL)scores,prostate volume,prostate-specific antigen(PSA),UDS and perioperative outcomes.UDS parameters included volume at first desire to void,volume at first urge to void,volume of severe urge,volume at capacity,compliance,detrusor contractions,maximum urinary flow rate(Qmax),and postvoid residual(PVR).Results:A total of 106 men were included in this analysis,who had urinary retention with a Foley catheter or clean intermittent catheterization(CIC)at the time of surgery.At baseline we found patients who voided had a detrusor pressure at Qmax(Pdet@Qmax)of 10.05±6.45 cmH2O compared to 16.78±12.17 cmH2O in those who did not void(p=0.071).Postoperatively,96(90.6%,mean age 76.9±26.2 years)of patients voided successfully while 10(9.4%,mean age 80.52±9.61 years)of patients remained in urinary retention.Mean baseline Qmax was 4.895±5.452 mL/s and 2.900±3.356 mL/s(p=0.087)in those who voided and did not respectively.PVR was 319.23±330.62 mL in those who voided and 276.88263.27 mL(p=0.344)in those who did not void.No UDS parameter predicted who would void postoperatively or improvements in QoL.Conclusions:The patients with DU and BPE might be able to successfully void after undergoing PVP regardless of UDS findings.All men who voided had improved international prostate symptom score and QoL scores compared to baseline and these parameters were durable up to 12 months. | Dominique Thomas Kevin C.Zorn Nadir Zaidi Stephanie Ashley Chen Yiye Zhang Alexis Te Bilal Chughtai | 2019 | Asian Journal of Urology2019，6，3： | 8 |
| 2 | The role of photovaporization of the prostate in small volume benign prostatic hyperplasia and review of the literature显示文摘Objective:Our objective was to characterize the safety and efficacy of the 180 W XPS-GreenLight laser in men with lower urinary tract symptoms secondary to a small volume benign prostatic hyperplasia(BPH).Methods:A retrospective analysis was performed for all patients who underwent 180 W XPSlaser photoselective vaporization of the prostate(PVP)vaporization of the prostate between 2012 and 2016 at two-tertiary medical centers.Data collection included baseline comorbidities,disease-specific quality of life scores,maximum urinary flow rate(Qmax),postvoid residual(PVR),complications,prostate volume and prostate-specific antigen(PSA).The secondary endpoints were the incidence of intraoperative and postoperative adverse events.Complications were stratified using the Clavien-Dindo grading system up to 90 days after surgery.Results:Mean age of men was 67.8 years old,with a mean body mass index of 29.7 kg/m2.Mean prostate volume as measured by transrectal ultrasound was 29 mL.Anticoagulation use was 47%and urinary retention with catheter at time of surgery was 17%.Mean hospital stay and catheter time were 0.5 days.Median follow-up time was 6 months with the longest duration of follow-up being 22.5 months(interquartile range,3-22.5 months).The International Prostate Symptom Score improved from 22.8±7.0 at baseline to 10.7±7.4(p<0.01)and 6.3±4.4(p<0.01)at 1 and 6 months,respectively.The Qmax improved from 7.70±4.46 mL/s at baseline to 17.25±9.30 mL/s(p<0.01)and 19.14±7.19 mL/s(p<0.001)at 1 and 6 months,respectively,while the PVR improved from 216.0±271.0 mL preoperatively to 32.8±45.3 mL(p<0.01)and 26.2±46.0 mL(p<0.01)at 1 and 6 months,respectively.The PSA dropped from 1.97±1.76 ng/mL preoperatively to 0.71±0.61 ng/mL(p<0.01)and 0.74±0.63 ng/mL at 1 and 6 months,respectively.No patient had a bladder neck contracture postoperatively and no capsular perforations were noted intraoperatively.Conclusion:The 180 W GreenLight XPS system is safe and effective for men with small volume BPH.PVP produced improvements in symptomatic and clinical parameters without any safety concern.It represents a safe surgical option in this under studied population. | Dominique Thomas Kevin C.Zorn Malek Meskawi Ramy Goueli Pierre-Alain Hueber Lesa Deonarine Vincent Misrai Alexis Te Bilal Chughtai | 2019 | Asian Journal of Urology2019，6，4： | 6 |
