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 < 0.05. Operative findings of 38 stented patients were outlined. Results Significant risk factors for emergency stenting were noted in males with larger (>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.

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, > 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.

PURPOSE: Define a group of patients with newly diagnosed prostate cancer, whose risk of bone metastasis is low enough to omit a bone scan staging study. MATERIALS AND METHODS: From 2003 to 2009, the medical records of patients who were newly diagnosed with prostate cancer were retrospectively reviewed. The data collected included: age, digital rectal examination, serum prostate specific antigen (PSA), Gleason score, clinical T stage, and bone isotope scan. Patients were divided into two groups according to the results of bone isotope scan; positive group and negative group. A univariate and multivariate binary logistic regression was used to analyze the results. RESULTS: Of the 106 patients, 98 had a complete data collection and were entered into the study. The median age of the patients was 70.5 years and patients with a positive bone scan was 74 years, significantly higher than for patients with negative scans (69 years) (p = 0.02). Bone metastasis was detected in 39 cases (39.7%). In all patients with clinical T1-2 stage, a Gleason score of < 8 and PSA = 20 ng/mL, the bone isotope scans were negative. In univariate analysis, PSA (> 20 ng/mL) and Gleason score (> 7) were independently predictive of positive bone scan, while clinical stage was not. CONCLUSION: Staging bone scans can be omitted in patients with a PSA level of = 20 ng/mL, and Gleason score < 8. Our results suggest that by considering the Gleason score and PSA, a larger proportion of patients with prostate cancer could avoid a staging bone scan.
