Article: Prevalence and management of complications of ureteroscopy: a seven-year experience with introduction of a new maneuver to prevent ureteral avulsion.
[show abstract] [hide abstract]
ABSTRACT: To evaluate the prevalence and type of rigid ureteroscopy complications and suggest a new method for ureteral avulsion prevention. Between March 2002 and March 2009, we retrospectively evaluated 2955 patients who had undergone diagnostic or therapeutic ureteroscopy for asymptomatic hematuria, migrated ureteral stent, or transurethral lithotripsy. They were enrolled from four hospitals in Ahvaz, Iran. Complications were encountered in 241 (8%) patients, including transient hematuria (4.2%), mucosal erosion (1.4%), stone migration (1.3%), ureteral perforation (1.2%), and fever and/or sepsis (1.0%). Ureteral avulsion occurred in 6 (0.2%) patients. Mostly, complications were managed conservatively, using ureteral stenting. Ureteral avulsions were managed using a new technique. In our series, the complication rate is comparable with the literature. A new technique was used in case of ureteroscope entrapment in the ureter, to lessen the occurrence of ureteral avulsion.Urology journal 01/2012; 9(1):356-60. · 0.58 Impact Factor -
Article: Detection of recurrent bladder cancer: NMP22 test or urine cytology?
[show abstract] [hide abstract]
ABSTRACT: To assess the accuracy of voided urine cytology versus urinary nuclear matrix protein 22 (NMP22) qualitative assay in the diagnosis of various grades and stages of recurrent bladder transitional cell carcinoma (TCC). From July 2007 to February 2009, all patients with history of superficial bladder TCC were included in this multi-center study. Each patient provided three serial voided urine samples for cytologic examination and one sample for the NMP22 qualitative assay prior to urethrocystoscopy. The sensitivity and specificity of urine cytology and the NMP22 test were determined. The sensitivities of the NMP22 test and cytology for detection of recurrence were 78.8% and 44.2%, respectively (P = .001), while the specificities were 69.6% and 83.7%, respectively (P = .019). The NMP22 test showed significantly higher sensitivity than cytology in detecting recurrences in low-risk and intermediate-risk groups. The NMP22 assay could be used for detection of superficial bladder cancer, especially in low- and intermediate-risk groups; however, the value of the test is limited by its low specificity.Urology journal 01/2012; 9(1):367-72. · 0.58 Impact Factor
