Abstract:
Objective To discuss the surgical treatment of contracted bladder caused by ketamine abuse. Methods Twenty-five ketamine male abusers were included in this study.The ages were from 19 to 28 years old and mean age was 24 years old.AIl of them had abused ketamine history for 0.7 tO 4.0 years,and presented with severe lower urinary tract symptoms.including severe frequency,urgency,urge incontinence,and painful haematuria.Urine cultures were negative.Hepatic function and renal function were normal.B ultrasound examination of 23 cases demonstrated the presence of bilateral hydronephrosis,the separation of renal pelvic was(1.8±0.7)cm.B ultrasound examination of 22 cases demonstrated residual urine was 45-1 50 ml,mean 80 m1.Twenty-three IVU investigations demonstrated the presence of bilateral hydronephrosis with calyces renales minores cycloidal expansion and bladder contraction.All the patients took the urodynamies with bladder capacity was (89±34)ml,end filling detrusor pressure was(48±26)cm H2O,Qmax was(7.8±2.3)ml/s,residual urine volume was(82±47)m1.All patients had cystoscopies and random biopsies performed showed ulcerative cystitis only.All patients were required to withdraw the narcotics and the experimental medicines were given without symptoms alleviated.Sigmoid cystoplasty was performed in all the 25 patients. Results The mean follow up was 18 months(rang 6 to 36).Compared with that before operation, bladder capacity increased to (375 ±53)ml, end filling detrusor pressure reduced to( 13 ±9)cm H2O, Qmax increased to(17.6±5.8)ml/s, residual urine volume reduced to(20±10)ml.Compared with the preoperative, there were statistically significant differences.There was no complained of urinary incontinence, enuresis, frequency, urgency.Urine routine examination was normal.IVU showed the vesicoureteral reflux disappeared in all patients, and calyces renales no expansion or calyces renales minores light degree expansion.B ultrasound examination that the separation of renal collecting was(1.0 ±0.5)cm. Conclusions Sigmoidcystoplasty could increase bladder capacity and compliance, lower the intravesieal pressure.It could improve the patients' quality of life.
