Emergency double-J stent insertion following uncomplicated Ureteroscopy: risk-factor analysis and recommendations

Purpose Emergency double-J (DJ) stenting following “uncomplicated” ureteroscopic (UURS) stone treatment is both morbid and costly. Our study aims at identifying those patients who are more likely to require such an extra procedure. Handling of this complication will also be highlighted. Materials and Methods 319 cases of UURS cases were selected out of 903 patients, who were admitted for URS stone treatment at King Abdullah University Hospital during the period from May, 2003 to December, 2010. Thirty-eight of them (11.9%) had emergency post-URS DJ stenting within 24 hours of discharge. The medical records of all UURS cases were retrospectively reviewed. Comparison in demographic and stone-related variables was made using 2-paired t-test with P 1.5 cm) and proximal stones (38 stented vs. 281 unstented). Operative risk factors among the 38 patients were: initial procedure time > 45 minutes (42.1%), ureteral wall edema (21.1%), repeated access for stones > 1.5 cm (21.1%), impacted stone (10.5%) and ignored or missed stones/fragments (4.6%). Conclusions The need for emergency DJ stenting following UURS stone treatment is not uncommon. The routine insertion is impractical and weakly-supported. With risk-factor stratification, selective and individualized DJ stenting policy is recommended

Does the duration of infertility affect semen parameters and pregnancy rate after varicocelectomy?: a retrospective study

OBJECTIVES: The most common indication for treatment of varicocele is still male subfertility. The aim of this study was to explore the effect of infertility duration on semen parameters and spontaneous pregnancy rate after varicocelectomy. MATERIALS AND METHODS: The medical records of 183 infertile patients with clinical varicocele were retrospectively reviewed. The patients were divided into three groups according to the duration of infertility (group I, 1-3 years, group II, 3-6 years and group III, &gt; 6 years). Total sperm motility counts (TMCs) before and after varicocelectomy and spontaneous pregnancy rate among these groups were statistically compared. RESULTS: The greatest changes, regarding preoperative and postoperative TMCs and spontaneous pregnancy rate were noticed between group I and III. Preoperative TMCs in group I and III was 15.2 ± 1.2, 7.8 ± 1.4, respectively (p < 0.05). Postoperative TMCs in group I and III was 33.7 ± 2.5, 25.2 ± 1.9, respectively (p < 0.05). An overall spontaneous pregnancy rate of 34.4% was achieved after inguinal varicocelectomy. The greatest spontaneous pregnancy rate was achieved in Group I (37.3%), and the lowest pregnancy rate in Group III (26.3%) (P < 0.05). CONCLUSIONS: Surgical varicocelectomy improves the total sperm motility counts especially in patients who have a TMCS more than 5 million and improves the spontaneous pregnancy rates. The improvement in the spontaneous pregnancy rates after varicocelectomy correlates negatively with the duration of infertility. Therefore, duration of infertility should be considered in treating a patient with a varicocele as a cause of infertility

Urodynamic Detrusor Overactivity in Patients with Overactive Bladder Symptoms

Purpose To evaluate the relationship between urodynamic detrusor overactivity (DO) and overactive bladder (OAB) symptoms in men and women. Methods We reviewed the records of adult males and females who attended a tertiary referral center for urodynamic evaluation of OAB syndrome symptoms with the presence or absence of DO. DO was calculated for symptoms alone or in combination. Results The overall incidence of DO was 76.1% and 58.7% in male and female OAB patients, respectively. Of men 63% and 61% of women with urgency (OAB dry) had DO, while 93% of men and 69.8% of women with urgency and urgency urinary incontinence (OAB wet) had DO. Of women, 58% who were OAB wet had stress urinary incontinence symptoms with 26.4% having urodynamic stress incontinence. 6% of men and 6.5% of women with OAB symptoms had urodynamic diagnosis of voiding difficulties with postvoid residual greater than 100 mL. Combination of symptoms is more accurate in predicting DO in OAB patients. The multivariate disease model for males included urge urinary incontinence (UUI) and urgency while for females it included UUI and nocturia. Conclusions There was a better correlation in results between OAB symptoms and the urodynamic diagnosis of DO in men than in women, more so in OAB wet than in OAB dry. Combination of symptoms of the OAB syndrome seems to have a better correlation with objective parameters from the bladder diary, filling cystometry, and with the occurrence of DO
