Does the Simple Renal Cyst Treatment Improve Renal Function: A Pilot Study.

Background: The current study aims to assess the effects of the large simple renal cyst (SRC) surgery on renal function for the first time. Materials and Methods: This case-series study included 22 patients with larger than 50 mm single SRC who underwent laparoscopic cyst unroofing surgery. Twenty-four-hour urinary protein, creatinine, and volume along with plasma creatinine and estimated glomerular filtration rate (GFR) were measured in patients before and 1 month after surgery. Patients underwent abdominopelvic computed tomography-scan without contrast and parenchymal thickness diameter adjacent to the cyst was measured before and after surgery. Results: Mean age and weight of patients were 52.2 ± 8.9 years and 77 ± 10.9 akg, respectively. There was no significant difference between plasma creatinine and GFR before and after surgery (P = 0.25 and 0.37, respectively). Twenty-four-hour urinary volume, creatinine, and protein before and after surgery revealed no significant changes (P = 0.37, 0.08, and 0.31, respectively). The mean improvement of parenchymal thickness diameter after surgery was 10.4 ± 0.7 mm which was statistically significant (P = 0.001). However, it was not correlated with the mean estimated GFR change (r = 0.349, P = 0.13). Conclusions: Although laparoscopic unroofing of renal cyst recovered renal parenchymal thickness noticeably, it did not improve renal function significantly; therefore, the latter factor lonely should not be considered a reason for surgery decision. Observation can be chosen as a safe treatment strategy in large SRCs without concern about renal function.

Hypothyroidism is prevalent among adult women with chronic lower urinary tract symptoms.

OBJECTIVE: To define the prevalence of hypothyroidism in women with chronic lower urinary tract symptoms (LUTS) and to compare the severity of each symptom between patients with hypothyroidism and controls. SUBJECTS AND METHODS: In this prospective observational study, we screened all adult women who came to the urology clinic between March 2017 and September 2020, and enrolled patients with chronic LUTS in the study. We assessed thyroid function. We evaluated the severity of voiding and storage urinary symptoms by the International Prostate Symptom Score. We also assessed the severity of urge urinary incontinence (UUI) and stress urinary incontinence (SUI). For between-group analysis, we selected age-matched cases and controls and compared them regarding the distribution and severity of urinary symptoms. RESULTS: Seven hundred and twenty-five women with a mean age of 51.7 ± 14.0 years were included in the final analysis. Two hundred fifty-eight patients (35.6%) had hypothyroidism. Age-matched case and control groups consisting of 210 patients each were selected. There was no significant difference in the severity and distribution of voiding LUTS and UUI between the study groups (P values >0.05). The severity of storage symptoms was lower in patients with hypothyroidism (P = 0.04). Sixty-seven patients with hypothyroidism (31.9%) had SUI, which was significantly higher than controls (23.3%) (P = 0.03). CONCLUSION: More than one-third of women with chronic LUTS have hypothyroidism which is much more frequent than in the general population. We also suggest a possible relationship between hypothyroidism and the severity of SUI and an inverse relationship between hypothyroidism and storage symptoms.

The effect of caudal epidural block on the surgical complications of hypospadias repair in children aged 6 to 35 months: A randomized controlled trial.

BACKGROUND: Caudal epidural block (CEB) in hypospadias surgery has the benefit of reducing post-operative pain and possibly intra-operative bleeding. Some studies, however, have suggested that this technique may increase the rate of post-operative complications. Considering the uncertainty about the effect of CEB on surgical complications of hypospadias repair, the current study was performed. OBJECTIVE: The aim of this randomized clinical trial was to compare the complication rates between patients who receive CEB after hypospadias surgery and those who did not. STUDY DESIGN: This double-blind randomized controlled trial was conducted on boys aged 6-35 months, who underwent hypospadias repair surgery in a university hospital from March 2018 to March 2019. Sixty patients were randomly divided into two groups (group A: 31 and group B: 29). In group B, CEB was performed, using 0.5 mg/kg of 0.125% bupivacaine (Marcaine). Postoperative complications including fistula, meatal stenosis, dehiscence, and occurrence of bleeding were assessed during six months after surgery. RESULTS: The patients were assessed for possible complications at 24 h, one week, one, three and six months after surgery. No remarkable differences were observed between the patients in the two groups in terms of the frequency of dehiscence, fistula, and meatal stenosis (P > 0.05). Moreover, the difference in complication rates between the patients with proximal and distal hypospadias did not reach statistical significance (P = 0.549). DISCUSSION: Assessment of complications showed no significant difference between the two study groups in terms of dehiscence, fistula, and meatal stenosis (Clavien type III). In addition, complication rate was not significantly different according to severity of hypospadias between the two groups. Our study had limitations such as short follow up and small sample size, which resulted in insignificant difference in complication rate between proximal and distal hypospadias. These limitations request large studies with long term follow up. CONCLUSION: The current study showed that the use of caudal block anesthesia in comparison with general anesthesia did not increase surgical complications, which approved CEB protocol as a safe method in hypospadias repair.

Diagnostic yield of fusion magnetic resonance-guided prostate biopsy versus cognitive-guided biopsy in biopsy-naive patients: a head-to-head randomized controlled trial.

BACKGROUND: The combination of MRI-guided targeted biopsy (MRGB) with systematic biopsy (SB) provides the highest accuracy in detecting prostate cancer. There is a controversy over the superiority of fusion targeted biopsy (fus-MRGB) over cognitive targeted biopsy (cog-MRGB). The present head-to-head randomized controlled trial was performed to compare diagnostic yield of fus-MRGB in combination with SB with cog-MRGB in combination with SB. METHODS: Biopsy-naive patients with a prostate-specific antigen level between 2 and 10 ng/dL who were candidates for prostate biopsy were included in the study. Multiparametric MRI was performed on all patients and patients with suspicious lesions with Prostate Imaging Reporting and Data System score of 3 or more were randomized into two groups. In the cog-MRGB group, a targeted cognitive biopsy was performed followed by a 12-core SB. Similarly, in the fus-MRGB group, first targeted fusion biopsy and then SBs were performed. The overall and clinically significant prostate cancer detection rates between the two study groups were compared by the Pearson χ2 test. McNemar test was used to compare detection rates yielded by SB and targeted biopsy in each study group. RESULTS: One-hundred men in the cog-MRGB group and 99 men in the fus-MRGB group were compared. The baseline characteristics of patients including age, PSA level, prostate volume, PSA density, and clinical stage were similar in the two groups (p > 0.05). Both the overall and clinically significant prostate cancer detection rates in the fus-MRGB group (44.4% and 33.3%, respectively) were significantly higher than cog-MRGB group (31.0% and 19.0%, respectively) (p = 0.035 and p = 0.016, respectively). CONCLUSION: The accuracy of identifying overall and clinically significant prostate cancer by fus-MRGB in biopsy-naive patients with PSA levels between 2 and 10 ng/dL is significantly higher than cog-MRGB and if available, we recommend using fus-MRGB over cog-MRGB in these patients.

Minimally invasive open pyeloplasty in children: Long-term follow-up.

OBJECTIVE: Our aim was to report the long-term follow-up for minimally invasive open pyeloplasty in children. MATERIAL AND METHODS: A total of 213 children with a mean age 16.33 months underwent miniature open pyeloplasty for ureteropelvic junction obstruction between January 2010 and May 2016. Anderson-Hynes dismembered pyeloplasty was performed through a subcostal miniature incision. The intraoperative and postoperative parameters including surgical operative time, incision size, intraoperative blood loss volume, postoperative analgesic use, hospital stay, complications, and success rate were documented. RESULTS: The mean surgery time was 65 min (50-85 min), and incision size was 16.99 mm (12-36 mm). None of the patients required blood transfusion or narcotic analgesics in the postoperative period. The mean hospital stay was 21.97 h (10-48 h). Minor side effects included urinary tract infection (3.8%) and urinary leakage in one case (0.004%). Major complications were not observed. The mean antero-posterior pelvic diameter before and after surgery was 28.69 ± 11.54 mm and 15.89 ± 9.29 mm, respectively with a mean difference of 12.78 mm, which shows a significant decrease (P value = 0.001). The success rate was 98.1% with a mean follow-up of 21.43 months (3-56 months). Two of the recurrences occurred in the first postoperative year, another one after 1.5 years, and the last one after 4 years. CONCLUSION: Our study confirms minimally invasive open pyeloplasty in children as a safe and efficient procedure with the least complication and hospital stay rate in comparison with other minimally invasive techniques. Moreover, long-term follow-up is a requirement in pyeloplasty surgery.

Electrocoagulation Accounts for a Significant Portion of Discrepancy Between Preoperative Ultrasonography Prostate Size Estimation and Resected Tissue Weight.

Background and Objectives: Transurethral resection of the prostate (TURP) is considered to be the gold standard surgical procedure for medium-sized prostates. However, there is a drastic difference between the weight of resected tissue reported by the pathologist and the sonographic estimate of prostate weight before the operation. The present study investigates the role of electrocoagulation in tissue loss during monopolar (M-) and bipolar (B-) TURP. Methods: In this experimental in vitro study, 33 prostate glands removed from patients by open suprapubic prostatectomy were roughly divided in half and the weight of each half was recorded precisely. One half of the specimen was resected using a monopolar resectoscope and the other half was resected by bipolar resectoscope in an out-of-body simulated condition. The weight of obtained chips was measured and the amount of lost tissue was calculated. Data from prostates with final pathologic diagnosis of benign prostatic hyperplasia were included in the analysis. The mean difference of prostate weight before and after out-of-body resection and also the proportion of tissue loss between M-TURP and B-TURP were compared using t-test. Results: Data from 62 prostate halves were included in the final analysis. The mean weight of samples after M-TURP was considerably lower than before resection (38.0 ± 6.9 and 48.7 ± 9.0, respectively, p < 0.001). Similarly, the mean weight of prostate samples after B-TURP was lower than the weight before resection (36.2 ± 7.3 and 48.4 ± 9.1, respectively, p < 0.001). However, the ratio of tissue loss in B-TURP (25.3% ± 2.5%) was significantly higher than in M-TURP (21.3% ± 3.7%) (p < 0.001). Conclusion: Prostate resection using electrocoagulation leads to a significant prostate tissue loss due to heat effect. Furthermore, tissue loss in B-TURP is slightly more than M-TURP.

Impact of varicocelectomy on urine dopamine value in patients with premature ejaculation and varicocele.

Dopamine is an important regulator of male sexual function and behaviour. Decreased levels of this substance have been observed in blood and seminal plasma of infertile men. Hence, this study was carried out to determine the impact of varicocelectomy on 24-hr urine dopamine values in patients with both premature ejaculation (PE) and varicocele. In this prospective study, 55 consecutive patients with premature ejaculation and grade 2 or 3 varicocele were enrolled. The urine dopamine level was measured in a 24-hr sample by HPLC method in a single laboratory centre. Two samples were gathered from each patient, one before and the other 1 month after varicocelectomy. The mean initial and final 24-hr urine dopamine levels were 259.6 ± 86.3 and 602.9 ± 88.4 micrograms, respectively, showing statistically significant increase (p = .0001), while there was no statistically significant difference between urine volume and creatinine. However, the change in intravaginal ejaculation latency time value was not statistically significant at this short time visit. According to our findings, varicocelectomy results in a significant increase in 24-hr urine dopamine levels in patients with premature ejaculation and varicocele. However, the effect of this change on premature ejaculation in the long term has yet to be determined.

A comparison between dextranomer/ hyaluronic acid and polyacrylate polyalcohol copolymer as bulking agents for treating primary vesicoureteral reflux.

PURPOSE: In recent years, endoscopic subureteral injection has gained popularity as a therapeutic alternative to open surgery because of its high success rates and low morbidity. We compared the success and complication rates of Polyacrylate polyalcohol copolymer (PPC) and Dextranomer/Hyaluronic acid (Dx/HA) in the endoscopic treatment of VUR. MATERIALS & METHODS: We retrospectively reviewed the patients who underwent endoscopic correction of their VUR by subureteric injection of PPC or Dx/HA from Jan 2010 to April 2016. The injection technique was STING (subureteric), distal HIT (intraureteric), and double HIT according the hydrodistention (HD) grade. The success rate, injection technique, injection volume, VUR grade, and obstruction rate were evaluated and compared between two groups. RESULTS: 107 renal refluxing units (RRU) with a mean age 55.23±36.58 months and 64 RRU with a mean age 52.13±31.66 months were treated in Dx/HA and PPC groups, respectively. The PPC group showed a more successful outcome in comparison to the Dx/HA group (92.2% versus 75.7% of the RRU with P value<0.001) at 3 months follow up. The injection technique was not significantly different between two groups. In PPC group the success rate was decreased significantly with increasing reflux grade but this reduction was not statistically significant in Dx/HA group. The injected volume was significantly more in PPC group; in addition, there was statistically significant correlation between injected volume of the bulking agent and obstruction rate. However, the obstruction rate did not establish significant difference between the two groups (P value=0.83), however it was earlier in Vantris (4 months versus 22 months). CONCLUSIONS: Our investigation approved PPC as a more effective material, regardless of other confounding variables such as reflux grade, learning cure, and technique of injection, in endoscopic treatment of VUR. In addition, the other remarkable point is this effectiveness is not accompanied by more post-operation obstruction.

The effect of selenium supplementation on cystine crystal volume in patients with cystinuria.

BACKGROUND: Cystinuria as an autosomal recessive sickness is a relatively rare disease. Formation of cystine stones indicates cystinuria. Few studies are considered the cysteine crystal volume in management of cystinuria. Selenium may inhibit organization of crystal stone, growth and stone aggregation. Since the role of selenium on inhibition of cystine crystal formation is not known, the aim of this study was to evaluate the effect of selenium supplementation on cystine crystals volume in patients with cystinuria. MATERIALS AND METHODS: This double-blind clinical trial study was conducted on 48 patients in Al-Zahra hospital, Isfahan, Iran from 2015 to 2017. These patients received selenium (200 mg/ daily) for 6 weeks. The urine crystal volume was evaluated before and after treatment. Data were entered SPSS and analyzed by Paired sample T test, Spearman and Pearson coefficient correlation. P- value < 0.05 was considered significant. RESULTS: In current study, mean cystine crystal volume before and after treatment was 6787.4 ± 11902.6 and 3110.9 ± 7225.4, respectively. Significant difference was observed before and after treatment in terms of cystine crystal volume (p < 0.001). No relation was observed between the mean cystine crystal volume with sex, age and type of medical procedures (p > 0.05). CONCLUSION: In this study, selenium treatment affected cystine crystal volume. It seems that selenium had the potential value to alleviate the volume of cystine crystal. Therefore, since reducing of cystine crystal volume decreases crystal formation, selenium may be effective to cure patients with cystinuria. However, age, sex and type of medical procedures did not affect cysteine crystal volume.

Effectiveness of caudal epidural block on interaoperative blood loss during hypospadias repair: A randomized clinical trial.

BACKGROUND: Intraoperative blood loss is considered to be an important issue in hypospadias surgery. Some studies have demonstrated the utility of caudal epidural block (CEB) in this regard among pediatric patients with hypospadias. Though there is evidence in favor of the use of CEB as the only anesthetic method for pediatric surgeries, it is usually used in combination with general anesthesia. In this form of use, it could have more favorable outcomes for both intra- and postoperative periods. There are few studies regarding the effectiveness of CEB on intraoperative blood loss. OBJECTIVE: We aimed to evaluate the utility of CEB on blood loss, operation time, and analgesic use during hypospadias repairs of pediatric population referred to our university hospitals. STUDY DESIGN: In this randomized clinical trial, consecutive patients with hypospadias who were candidate for surgery were enrolled and randomly allocated to one of the two groups: group A received caudal epidural block (CEB) plus general anesthesia (GA) before surgery and group B received only GA. Intraoperative blood loss, operation time, and dose of fentanyl used during the procedure were recorded and compared. All surgeries were performed by a single pediatric urologist in two different university hospitals that was not blinded to the study groups. RESULTS: In this study, 57 pediatric patients with hypospadias who underwent surgical repair were studied, from which 29 and 28 patients were allocated to receive or not to receive preoperative CEB, respectively. The patients' age, weight, ASA, score and severity of hypospadias were not significantly different between the two groups. The operation time was significantly lower in the CEB before surgery group (p < 0.05). The mean dose of fentanyl and volume of blood loss during procedure were lower in the CEB group, although for fentanyl it approached but did not reach statistical significance. CONCLUSION: The findings of current study indicated that caudal epidural anesthesia in addition to general anesthesia has a favorable effect on reducing blood loss during operation, operation time, and analgesic use. Our data confirm the findings of previous studies in this field. Further studies are recommended to evaluate the effect of this type of analgesia in other outcomes of hypospadias repair surgery. Our results could be used for revising existing surgical guidelines for better management of hypospadias.

Reliability and Validity of the Persian Language Version of the International Consultation on Incontinence Questionnaire - Male Lower Urinary Tract Symptoms (ICIQ-MLUTS).

OBJECTIVES: Assessment instruments are essential for research, allowing diagnosis and evaluating treatment outcomes in subjects with lower urinary tract disorders of both genders. The purpose of this study was to translate the Male Lower Urinary Tract Symptoms (MLUTS) Questionnaire and determine its psychometric properties in Persian subjects. METHODS: After getting permission from the International Consultation on Incontinence Modular Questionnaire (ICIQ) web site, the forward and backward translation of the MLUTS questionnaire were carried out by researcher team. The content/face validity, construct validity and reliability were assessed in a sample of MLUTS Iranian patients by measuring with the Cronbach's alpha test. RESULTS: In total, 121 male patients were included in the study. The mean age of the patients was 60.5 years. Cronbach alpha value was 0.757, consecrated the internal consistency of the form (r > 0.7). The internal consistency of each question was examined separately and found to be over 0.7. For the evaluation of reliability test-retest was done, the test was administered to 20% of the patients for a second time with an interval of 1-2 weeks. The intraclass correlation coefficient (ICC) score was 0.901. The Correlation coefficient between the MLUTS and International Prostate Symptoms Score (IPSS) was 0.879. CONCLUSIONS: ICIQ-MLUTS is a robust instrument, which can be used for evaluating male LUTS in Persian patients. We believe that the Persian version of the MLUTS is an important tool for research and clinical setting.

Urinary carbohydrate antigen 19-9/creatinine ratio: A non-invasive marker for follow-up of unilateral ureteropelvic junction obstruction in children.

INTRODUCTION: Ureteropelvic junction obstruction (UPJO) is the most common cause of hydronephrosis in children. One major challenge in the management of UPJO is to select the patients that must be subjected to early obstruction relief. Currently, there is no gold standard for this assessment. Therefore, the aim of the present study was to evaluate the urinary levels of carbohydrate antigen (CA) 19-9 and normalized CA 19-9 (Ca 19-9/Cr ratio) in UPJO patients before and after surgery and compare them with a control group to assess their potential clinical application as an assisting tool in diagnosis of UPJO patients. MATERIAL AND METHODS: From Jan 2013 to Jun 2016, 30 children with history of inguinal hernia, circumcision, hydrocele, and undescended testis as the control group (group 1) and 30 children with unilateral congenital UPJO (group 2) were enrolled in the study. Random CA 19-9 and random creatinine were measured in the voided urine samples of control group and proven congenital UPJO group preoperatively (group 2A) and at 6 months after dismembered pyeloplasty (group 2B). In addition, the random urinary CA 19-9/CR ratio was evaluated as a marker to normalized urinary CA 19-9. DISCUSSION: The urinary CA 19-9/Cr ratio was significantly greater in the UPJO group than in the control group. The urinary CA 19-9 also was more in group 2A than in group 1; however, it was not statistically significant. The urinary CA 19-9/Cr ratio and renal pelvis anteroposterior diameter decreased significantly in the group 2B 6 month after complete relief of obstruction in comparison with group 2A preoperatively. Urinary CA 19-9 also decreased in 2B group though it was not significant. CONCLUSION: Urinary CA 19-9/Cr ratio is suggested as a non-invasive marker that can assist in diagnosis and long-term follow-up of UPJO patients. This ratio is superior to urinary CA 19-9 as it is more strongly correlated with UPJ obstruction.

Is there any Relationship Between Bladder Trabeculation and Efficacy and Safety of Intravesical Botulinum Toxin A Injection in Refractory Idiopathic Overactive Bladder Women?

BACKGROUND: Intradetrusor injection of botulinum toxin A (BTX-A) might serve as a minimally invasive substitute in patients with refractory idiopathic overactive bladder (RIOAB). The aim of this study was to evaluate the clinical outcomes related to two different doses of abo-BTX-A (AboBTX-A) in patients with RIOAB. MATERIALS AND METHODS: This prospective clinical trial was performed on 55 women with RIOAB. After determination of trabeculation grade, 300 (no or mild) or 500 (moderate or severe) unit of AboBTX-A (Dysport) was intravesicaly injected. Before 1, 3, and 6 months after intervention, lower urinary tract symptoms during 24 h were recorded. RESULTS: Of the study population, 62% had severe bladder trabeculation. The mean duration of overactive bladder (OAB) was 1.76 versus 5.85 years, for no or mild versus severe trabeculation, respectively. After injections of 300- and 500-unit dosage, there were 19% and 26% early complications such as urinary retention. There was a statistically significant difference between the two groups in OAB score after 1 month (P < 0.001) and duration of OAB symptoms, over three follow-up times (P < 0.001). The mean preinjection OAB scores between patients with and without recurrence were statistically significant (29.36 vs. 25.07; P < 0.03). Urinary tract infection as a late complication was distinguished in four patients. CONCLUSION: In RIOAB, by adjusted dosage of AboBTX-A related to the grade of bladder trabeculation, in addition to maintain efficacy, consequent complications might not be affected by dosage and the drug dosage could be increased to nearly 60% with less concern associated to complication.

Comparison of Two Treatment Methods "One Shot" and "Sequential" on Reduction the Level of Hemoglobin in Patients with Percutaneous Nephrolithotripsy in Al Zahra Hospital in 2012-2013.

BACKGROUND: Access dilation is the most important part of percutaneous nephrolithotripsy (PCNL) that is done by different methods, especially metal telescoping and one shot. In this study, two different methods of access dilation one shot and telescoping were compared. MATERIALS AND METHODS: In observational cross-sectional study, 240 patients who were a candidate for PCNL were selected and randomly divided into two groups. The first group was undergone one-shot method and the second group was undergone telescoping method. The decrease in hemoglobin (Hb), duration of hospitalization and the time of radiation exposure during access dilation was compared in two groups by SPSS software version 21, (SPSS Inc., Chicago, IL, USA). RESULTS: The decrease of Hb level after intervention in one-shot group was 1.08 ± 1.23 g/dl and in telescoping, group was 1.51 ± 1.08 g/dl with no difference statistically (P = 0.37). The mean duration of hospitalization in one shot and telescoping group were 2.36 ± 0.67 and 2.28 ± 0.61 days, respectively. According to t-test, there was no significant difference between the two groups (P = 0.37). Average radiation exposure in one shot group was 7.13 s and in telescoping, group was 35.75 s, and there was a significant difference between the two groups (P < 0.001). CONCLUSION: One-shot method is superior to telescoping method due to less time for radiation exposure and no more blood loss and other complications during PCNL.

Is it Necessary to Perform Nephrostography before Tube Removal after Percutaneous Nephrolithotomy.

BACKGROUND: The aim of this study is the caparison of the complications rate among the patients which underwent nephrostomy removal with and without performing nephrostography. MATERIALS AND METHODS: Between October 2010 and November 2011, 200 patients who underwent standard percutaneous nephrolithotomy (PCNL) procedures were included in this study. The patients were randomly assigned into two groups, Group A (n = 100) did not undergo the antegrade nephrostography on postoperative day 2 and the patients were discharged keeping the nephrostomy until postoperative day 3, while in Group B (n = 100) the nephrostomy tube was removed on postoperative day 3 after antegrade nephrostography demonstrating ureteral drainage down to the bladder. Postoperative complications in both groups were recorded and compared between two groups. RESULTS: A total of 200 patients were treated with standard PCNL. The persistent leakage of urine after removal of the nephrostomy tube was encountered in 5 (5.0%) and 3 (3%) of patients in Groups 1 and 2, respectively. Urinary leakage was resolved with conservative management in 3 and 2 patients of Groups 1 and 2, respectively, but a double-J stent was inserted in 2 and 1 patients in each group because of persistent leakage of urine more than 1-week. The two groups show comparable complications such as prolonged urinary leakage which managed in a similar manner, however, postoperative hospital stay was lesser in Group 1. CONCLUSION: Our results revealed postoperative performing nephrostogramy before tube removal changed the planning of complications such as prolonged urinary leakage and could be omitted in cases.

Addition of Ceftriaxone and Amikacin to a Ciprofloxacin plus Metronidazole Regimen for Preventing Infectious Complications of Transrectal Ultrasound-Guided Prostate Biopsy: A Randomized Controlled Trial.

Background. The objective of this study was to evaluate the efficacy of adding single doses of ceftriaxone and amikacin to a ciprofloxacin plus metronidazole regimen on the reduction of infectious complications following transrectal ultrasound-guided prostate biopsy (TRUS Bx). Materials and Methods. Four hundred and fifty patients who were candidates for TRUS Bx were divided into two groups of 225 each. The control group received ciprofloxacin 500 mg orally every 12 hours together with metronidazole 500 mg orally every 8 hours from the day prior to the procedure until the fifth postoperative day. In the second group, single doses of ceftriaxone 1 g by intravenous infusion and amikacin 5 mg/kg intramuscularly were administered 30-60 minutes before TRUS Bx in addition to the oral antimicrobials described for group 1. The incidence of infection was compared between the groups. Results. The incidence of infectious complications in the intervention group was significantly lower than that in the control group (4.6% versus 0.9%, p = 0.017). Conclusion. The addition of single doses of intramuscular amikacin and intravenously infused ceftriaxone to our prophylactic regimen of ciprofloxacin plus metronidazole resulted in a statistically significant reduction of infectious complications following TRUS Bx.

Efficacy of Long-Acting Octreotide on Reducing Mucus Production in Patients With Ileal Neobladder.

PURPOSE: To evaluate the efficacy of long-acting-release octreotide (trade name Sandostatin) on decreasing mucus secretion, thus reducing catheter obstruction after radical cystectomy and orthotopic reconstruction. PATIENTS AND METHODS: In this double-blind, placebo-controlled study, we treated 73 cases of radical cystectomy between the years 2008 and 2014; 65 were deemed eligible for the study. Cases were randomly divided into 2 groups. Group A (n = 32) received 2 doses of 20 mg intramuscular long-acting-release octreotide 4 weeks before and on the day of surgery, while group B (n = 33) received placebo. Catheter irrigation was only performed when there was an obstruction due to a mucus plug. The need for catheter irrigation and the volume of mucus produced by the neobladder were evaluated and compared between the 2 groups. RESULTS: The average number of neobladder irrigations required to treat mucus plugs was 2.3 ± 1.5 in group A and 9.5 ± 4.3 in group B (P < .001) before hospital discharge. This number changed to 2.5 ± 1.5 versus 11.4 ± 2.7 in groups A and B, respectively (P < .001), after discharge from the hospital. The 24-hour mucus production at the end of the first week was 5.4 ± 2.7 mL versus 21.5 ± 5.6 mL in groups A and B, respectively (P < .001). At the end of the third week, this amount changed to 5.5 ± 2.3 mL versus 21.8 ± 5.6 mL in groups A and B, respectively (P < .001). CONCLUSION: Two injections of long-acting-release octreotide can dramatically reduce mucus production and hence catheter obstruction due to mucus plugs after radical cystectomy and orthotopic reconstruction.

The efficacy of fibrin glue injection in the prostatic fossa on decreasing postoperative bleeding following transurethral resection of prostate.

BACKGROUND: To evaluate the efficacy of fibrin glue injection in the prostatic fossa at the end of transurethral resection of prostate (TURP), in decreasing postoperative bleeding in patient with benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: In this prospective randomized clinical trial, sixty patients with BPH, who were a candidate for TURP, were randomly divided into two equal groups. In the intervention group, 10cc of fibrin glue was injected in the prostatic fossa at the end of the surgery; through a 5 Fr feeding tube attached to Foley catheter and its tip was proximal to the balloon of catheter. The other thirty patients created the control group. Hemoglobin (Hb) level and lower urinary tract symptoms (LUTS) score were recorded before and 6, 24, 48 h, and 5 days after TURP. RESULTS: The mean age of the patients and prostate volumes were comparable between the groups. The mean Hb level before and 6 h after TURP were not different between the two groups, however, 24 and 48 h and 5 days after TURP, there was a significant difference as well as a higher decrease in the mean Hb level of the control group (P = 0.023). The mean LUTS score was not statistically different between the two groups. CONCLUSION: Fibrin glue injection in the prostatic after TURP reduces postoperative bleeding without any effect on LUTS score in patients with BPH.

Outcomes of Patients with Glanular Hypospadias or Dorsal Hood Deformity with Mild Chordee Ttreated by Modified Firlit's Technique.

PURPOSE: To assess the success and complication rates of glanular hypospadias or dorsal hood deformity surgery,using a modified Firlit's technique without glanuloplasty. MATERIALS AND METHODS: Between May 2013 and December 2015, 41 patients with glanular hypospadias or dorsalhood deformity without hypospadias and mild ventral chordee underwent surgery. Thirty-eight who completedthe 1 week and 6-month follow-up were retrospectively evaluated. Exclusion criteria were complete absence ofcorpus spongiosum resulting in very thin distal urethra, moderate to severe ventral chordee or deep urethral platethat seemed to be better served by tubularization techniques. Modified Firlit's technique (a submeatal inverted Vincision in addition to the classic technique) was applied to all patients. RESULTS: The mean age was 20.4±13 months (range: 6-52 months). The only complication was a narrow-bandventral skin necrosis in 1 patient (2.6%) that was replaced by new skin growth without need for further intervention.No other complications including unresolved chordee, urethrocutaneous fistula, meatal stenosis, hematoma,infection or post-operative bleeding was observed. Defining the satisfactory result as the glanular position of themeatus and the absence of residual chordee, all patients had satisfactory outcome. CONCLUSION: Modified Firlit's technique is a simple method with excellent cosmetic results and low complicationrate that avoids unnecessary glans dissections. When prepucioplasty is not desired, this technique can be consideredas a viable option.

Potential risk factors associated with stress urinary incontinence among Iranian women.

BACKGROUND: Stress urinary incontinence (SUI) is considered as one of the major hygienic problems among women. The main aim of the study is to assess the potential risk factors associated with SUI among Iranian women. MATERIALS AND METHODS: This study was conducted on 90 married women with history of SUI diagnosed by an urologist and were selected randomly. Their pelvic muscles contraction (PMC) and the history of the subjects were assessed for some of risk factors such as age, height, weight, body mass index (BMI), pregnancy history, miscarriage, type of delivery (normal vaginal delivery or cesarean section), number of offspring born healthy in addition to other risk factors such as chronic cough, constipation and hypothyroidism by use of POP Questionnaire. Data were analyzed using Pearson correlation coefficient and SPSS version 18 Software. RESULTS: There was a significant relation between SUI and height (P < 0.05, r = 0.45), vaginal delivery (NVD) (P < 0.05, r = 0.2), number of genitourinary surgery (P < 0.05, r = 0.42), hypothyroidism and constipation (P < 0.05). An inverse relatively strong significant relation was found between SUI and cesarean section (P < 0.05, r = -0.50) No significant relation was found between SUI and weight, BMI, age, chronic cough and miscarriage, and other study parameters. An inverse significant relation between PMC and weight (P < 0.05, r = -0.52), BMI (P < 0.05, r = -0.42) and number of genitourinary surgery (P < 0.05, r = -0.18). CONCLUSION: Cesarean section had a preventive effect on SUI versus normal vaginal delivery. The rate of SUI was higher in taller women or those suffering from hypothyroidism or constipation or who had genitourinary surgery. The women with high BMI had lower pelvic floor muscles strength.
