ABSTRACT
Objective To study the clinical value of ultrasonography in the diagnosis of ketamine associated cystitis. Methods 60 cases were confirmed by pathological examination to determine the occurrence of ketamine associated cystitis in clinic, all patients underwent ultrasound examination, recording bladder morphology, wall thickness, cavity size (thickness, diameter, length and diameter), calculation of residual urine volume and bladder capacity according to the relevant data. The pictures were assigned to 2 or more specialists, and the double blind scan was used. The ultrasonographic findings of 60 patients with ketamine associated cystitis were recorded and compared with the pathological diagnosis. Results 60 cases of ketamine related cystitis were successfully examined with no interruption and withdrawal. The success rate of ultrasonography was 100.00％. The analysis showed that the coincidence rate of ultrasonography and pathological diagnosis was 60 (91.67％ and 8.33％) respectively, and there was no significant difference between the two groups. Conclusion the use of ultrasound has a detection rate of ketamine associated cystitis ideal, to provide a reliable basis for the diagnosis and treatment of ketamine associated cystitis doctor, has important value on the quality of life of patients with treatment effect and security.
ABSTRACT
Objective To study the long-term efficacy of bladder pressure expansion and perfusion therapy by bladder hydraulic expansion with alkalify lidocaine,heparin,dexamethasone for the treatment of ketamine correlation cystitis Methods From January 2008 to September 2011,the data from 19 male and 3 female patients,who were diagnosed as ketamine-associated cystitis was retrospectively analyzed.The mean age was (26 ± 5)years old.All patients accepted bladder pressure expansion under the spinal and epidural anesthesia.After expansion,the silicon three-channel catheters were left in those patients.2％ lidocaine (20 ml) and 5％ bicarbonate (10 ml) was perfused into the bladder.Meanwhile,the heparin (2.5 U) and dexamethasone (10 mg) were added into the solution,as well.After perfusion,the catheter was clamped until the patient could not tolerate.The perfusion was performed three times every day for 5 days.The volume of urine was recorded each time.The OABSS score,urine volume,maximum urine flow rate,day and night urination frequency were followed within 5 years.And the data was compared with those preoperative and postoperative 1 week,1 month,3 months,6 months.Results 22 patients accepted the procedure successfully.No complications,such as fever or bladder rupture,occurred.At the end of 5 years,the bladder volume daily urinating frequency,night urinating frequency,maximal flow rate,OABSS score were (238.3 ± 37.3) ml,9.2 ± 2.3,2.1-± 1.3,(18.2 ± 8.3) ml/s,4.4-± 2.4,respectively.Compared to the one week and one month after the operation,those results have significant difference (P ＜ 0.01).Compared to the 3 months after the procedure,the bladder volume has significant difference [(238.3-± 37.3) ml vs.(158.3-± 18.3) ml,P ＜ 0.01].No significant differences were noticed in those items 6 months after the procedure (P ＞ 0.05).Conclusion The long-term efficacy of bladder pressure expansion with alkaline lidocaine,heparin and dexamethasone the anesthesia in the treatment of ketamine associated cystitis is good.The outcome is stable,and no obvious complications.
