To investigate whether a Percutaneous nephrostomy (PCN) has any impact on the success rate of shock wave lithotripsy (SWL) and to estimate the probability of stone-free in SWL patients with upper ureter stones.

Overall, 236 patients who underwent SWL for upper ureter stones between 2015 and 2019 were evaluated. Forty-nine patients who underwent PCN during SWL were identified. Medical data of the patients were retrospectively reviewed, and possible prognostic features were evaluated.

Out of all patients, 147 patients were selected through propensity score matching. There were no significant differences between the PCN and no PCN groups, except for a lower stone-free rate (55.1% vs. 74.5%, p = .018) and one-session success rate (24.5% vs. 50.0%, p = .003) in the PCN group. In univariate analysis, a younger age, the female sex, a smaller size of stone, lower mean stone density (MSD), and absence of PCN were positive predictive factors of being stone-free in patients who underwent SWL. In multivariate analysis, a smaller size, lower MSD, and absence of PCN were positive predictive factors of being stone-free in patients who underwent SWL.

Stone size, MSD, and PCN were prognostic factors that influence the outcome of SWL. The presence of PCN during SWL is associated with adverse success rates in patients with upper ureter stones.

To compose a comprehensible and fluent Persian translation of the National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI), and to determine its linguistic validity in a Persian sample population.

The standard double-back translation method, provided by the previous studies were utilized by three professional linguists to translate the English version of the NIH-CPSI to Persian, and a group of 10 urologists fur-ther reviewed and translated questionnaire. The questionnaire was then presented to the sample study, comprised of 60 men with CP/CPPS and 60 controls with adverse urological history, and the collected data was analyzed through IBM-SPSS software to test its validity, evaluative, and discriminatory power, psychometric qualities and internal consistency.

A total of 80 subjects (42 CP/CPPS patients and 38 healthy controls) were considered eligible for this study. The total Persian NIH-CPSI scores and each subdomain showed significant difference (P < 0.001) between the two study groups, indicating a satisfactory discriminant validity for the index. Psychometric analysis estab-lished the index to benefit from a high internal consistency. The translation was also considered by both the sub-jects and the physicians to be easily comprehensible.

The Persian NIH-CPSI is a reliable and valid instrument for evaluating CP/CPPS symptoms in gener-al population, while also benefitting from high discriminatory power, and can be utilized with ease in both clinical practice and laboratory studies

  It remains unclear whether laparoscopic radiofrequency ablation (RFA) for primary treatment of small renal masses is similar to partial nephrectomy (PN) in terms of long-term oncological and renal function outcomes. We reviewed the long-term outcomes for patients with T1a renal masses treated with either laparoscopic RFA or
PN. This retrospective single-center study on 115 patients who were treated by laparoscopic RFA or PN for small (<4 cm) renal masses between January 2005 and October 2014 at Chungnam National University Hospital. Estimated glomerular filtration rate (eGFR) was measured before and 1–2 weeks after surgery and at last follow-up. The laparoscopic RFA and PN groups were compared in terms of clinical characteristics data and change in eGFR after surgery using the Chi-squared test or Student’s t-test. Survival data were analyzed using the
Kaplan-Meier method and the log-rank test. Of the 115 patients, 62 and 53 underwent laparoscopic RFA and PN, respectively. Their mean (range) follow-up duration was 60 (30–104) and 68 (30–149) months, respectively (P = 0.092). The RFA patients were older (P = 0.023) and had smaller tumors (P = 0.000). RFA associated with shorter operation and hospitalization times and less perioperative blood loss (all P<0.001). The groups did not differ in terms of change in eGFR 1–2 weeks after surgery (P = 0.252) or at the last follow-up (P = 0.395) or 5 year survival rates (P = 0.360). Laparoscopic RFA for small renal masses was comparable to PN in terms of oncological and functional outcomes and associated with shorter operative and hospitalization times and less perioperative bleeding.

This study was conducted to evaluate lower urinary tract symptoms (LUTS) change in patients with localized prostate cancer after radical retropubic prostatectomy (RRP) and examine the efficacy of anticholinergic drugs to treat patients suffering from storage symptoms.
Among 50 patients who underwent RRP for prostate cancer, 40 who did not undergo additional treatment that might affect their urination pattern were included in the analysis. The International Prostate Symptom Score (IPSS), quality of life (QoL) score, and uroflowmetry were analyzed prior to RRP and 12 months after RRP. Twelve months after RRP, patients desiring improvement of storage symptoms were administered anticholinergic drugs for 6 months; the effects of such treatments were analyzed 3 and 6 months later.
Preoperatively and at 12 months after surgery, the mean IPSS for patients were 10.9 ± 6.7 and 9.2 ± 5.7, respectively. The mean IPSS for patients desiring improvement of storage symptoms before and after administration of medication were 9.7 ± 5.9 and 9.0 ± 4.4, respectively. In particular, the mean storage symptom composites improved significantly after administration of medication. There were no statistically significant differences in frequency between baseline and 3-month, but frequency was improved significantly after 6 months. Urgency and nocturia were improved significantly after 3 months.
In patients undergoing RRP, urinary symptoms change over time, with worsening storage symptoms. Our results suggest that, in patients who had discomfort with storage symptoms after RRP, anticholinergic drugs significantly improved symptoms and QoL.
