Most disorders of the lower urinary tract are functional, so diagnoses are typically based on urodynamic findings. Treatment is likely to fail if the pathology is not correctly diagnosed..
There are various diagnostic tests for lower urinary tract symptoms (LUTS). In this study, we evaluated the value of urodynamic testing to diagnose the causes of lower urinary symptoms in male patients..
Patients and Urodynamic tests were performed in 407 patients referred to the urology clinic in Baqiyatallah in 2014 with complaints of LUTS, and the diagnosis was based on the findings of the tests..
The mean age of patients in this study was 50.88 years, and most patients were in their third decade (20 - 30 years of age). Urinary frequency (28.8%), enuresis (22.22%), and incontinence (16.12%) were the most common complaints. The most prevalent disorder was bladder sensation disorder..
Patients made various complaints, and several pathologies were diagnosed, which emphasizes the importance of using urodynamic tests for subsequent medical approaches as a non-invasive, accessible, and inexpensive tool..

Childhood hypertension has been associated with target-organ damage in young adults. It is often asymptomatic in both children and adolescents; when persistent, and long-standing, it could be a significant risk factor for kidney damage and increased glomerular permeability..
Burden of hypertension and its impact on glomerular permeability were prospectively determined in randomly recruited primary school children..
Patients and Blood pressure (BP) measurement was performed by the auscultation method, and abnormal glomerular permeability was assessed by dipstick testing of urine for persistent proteinuria and/or hematuria for ≥ three months in hypertensive children..
Of 1,335 pupils aged 10.0 ± 2.4 (6.0 - 14.0) years, 33 (2.5%) were hypertensive. Overall mean systolic/diastolic BP was 125.6 ± 6.5/81.7 ± 3.3 (range: 114.0 - 140.0/80.0 - 90.0) mmHg. Nine (27.3%) had combined systolic and diastolic hypertension, 126.7 ± 5.7/80.0 - 80.0 ± 0.0 (120.0 - 130.0/80.0 - 80.0) mmHg. Isolated systolic hypertension, 125.4 ± 6.7 (114.0 - 140.0) mmHg, was present in 14 (42.4%), whereas 10 (30.3%) had isolated diastolic hypertension, 82.0 ± 3.5 (80.0 - 90.0) mmHg. Mean systolic and diastolic BP were 131.0 ± 3.3 (130.0 - 140.0) mmHg and 86.5 ± 4.43 (80.0 - 90.0) mmHg, respectively. According to the dipstick test, none of the hypertensive pupils showed urinalysis evidence of proteinuria and/or hematuria after three months of testing..
Although the burden of hypertension was 2.5%, the dipstick method did not detect any hypertension-related abnormal glomerular permeability in the school children..

Prostate traction is one way to control post-prostatectomy bleeding. The most popular method involves traction with a catheter fixed to the thigh with adhesive bands. However, this method has its own drawbacks..
We aimed to simplify this traction procedure and to overcome its disadvantages..
Patients and From 2007 - 2015, a new method was used to control post-prostatectomy bleeding in 152 patients. This technique involved inducing pressure on the prostate neck with an indwelling catheter attached to a partially filled urine bag to control bleeding after a prostatectomy..
The new method effectively controlled post-prostatectomy bleeding. A few patients required surgical intervention..
Post-prostatectomy catheter traction using a semi-filled urine bag was an acceptable alternative to the standard method to control post-operative bleeding..

Opioids are generally the preferred analgesic agents during the early postoperative period..
The present study was designed to assess and compare the multimodal analgesic effects of ketamine and tramadol in combination with intravenous acetaminophen after renal surgery..
Patients and This randomized, double-blinded, clinical trial was conducted on 80 consecutive patients undergoing various types of kidney surgeries in Sina hospital in Tehran in 2014 - 2016. After extubation, the patients were randomly assigned to receive intravenous paracetamol (1 gr) plus tramadol (0.7 mg/kg) (PT group) or paracetamol (1 gr) plus ketamine (0.5 mg/kg) (PK group) within ten minutes. Pain severity was assessed by the visual analog scale (VAS), and the level of agitation was assessed by the Ramsey sedation scale (RSS). Morphine consumption was assessed within the first six hours after drug injection, and hemodynamic parameters were assessed at 5, 10, and 20 minutes after infusion, at the time of transfer from recovery to the ward, and also at one and six hours after transfer to the ward..
Postoperative pain scores were significantly lower in the PK group than in the PT group during all study time points. The mean dose of morphine needed at recovery in the PK group was lower compared with the PT group (0.47 ± 0.94 mg versus 1.50 ± 1.35 mg/P = 0.001). The level of agitation based on the RSS score was significantly lower in the PK group than in the PT group at 10 and 20 minutes after drug administration. The total postoperative complication rate in the PK group was lower than in the PT group (20% versus 53.3%, P = 0.007). In this regard, catheter bladder discomfort was more frequent in the PT group than in the PK group (43.3% versus 3.3%, P The combination of intravenous paracetamol 1 gr and ketamine 0.5 mg/kg resulted in an overall reduction in pain scores, decreased postoperative analgesic requirements, and lower agitation score compared with intravenous paracetamol 1 gr and tramadol 0.7 mg/kg for patients undergoing renal surgery..

Chronic kidney disease (CKD) is a major public health problem. The eventual outcome of CKD is end-stage renal disease (ESRD). Early diagnosis and proper management play an important role in preventing CKD progression to ESRD. Dialysis and kidney transplantation are the only treatment options available for patients suffering from ESRD..
This study was designed to investigate the etiological role of recipient and donor characteristics on serum creatinine changes within the follow-up period, graft failure risk, and the impact of longitudinal serum creatinine levels on graft survival after renal transplantation..
Patients and This study was carried out at the department of nephrology, Baqiyatallah hospital, Baqiyatallah University, Tehran, Iran, between April 2005 and December 2008. During that time period, 461 patients who had undergone renal transplantation were entered in the current study. Time to graft loss and serum creatinine levels at each visit were the primary data gathered for the study. A joint modeling of survival and longitudinal nonsurvival data was used to assess the association between the two processes and investigate the influential factors..
Median follow-up time was 6.80 months. A linear decreasing trend in serum creatinine level over time was found (P The major finding of this study is that one unit increase in serum creatinine level suggests an increased risk of graft failure of up to four times..

Hemoglobin levels measured after hemodialysis, as compared to hemoglobin levels measured before hemodialysis, are suggested to be a more accurate reflection of the hemoglobin levels between hemodialysis sessions, and to be a better reference point for adjusting erythropoietin dosing..
The aim of this study was to compare the hemoglobin levels before and after hemodialysis, to calculate the required erythropoietin doses based on these levels, and to develop a model to predict effective erythropoietin dosing..
Patients and In this cross-sectional study, the hemoglobin levels of 52 patients with end-stage renal disease were measured before and after hemodialysis. The required erythropoietin doses and the differences in cost were calculated based on the hemoglobin levels before and after hemodialysis. A model to predict the adjusted erythropoietin dosages based on post-hemodialysis hemoglobin levels was proposed..
Hemoglobin levels measured after hemodialysis were significantly higher than the hemoglobin levels before hemodialysis (11.1 ± 1.1 vs. 11.9 ± 1.2 g/dL, P Using post-hemodialysis hemoglobin levels as a reference point for erythropoietin dosing can result in significant dose and cost reduction, and can protect hemodialysis patients from hemoconcentration. The prediction of the erythropoietin adjusted dosage based on post-hemodialysis Hb may also help in avoiding overdosage..

Chronic renal failure (CRF) causes a gradual decline in kidney function to the extent that CRF patients need long-term clinical care, which affects the patients’ family function and quality of life (QoL)..
The present study was conducted to study the effects of the family-centered empowerment model on QoL in children with CRF during 2012-2013..
Patients and In this quasi-experimental study, 68 children with CRF and their parents were randomly assigned to two groups, intervention and control, via a random numbers table. An empowerment program was then conducted over the course of seven 45-minute sessions, and a questionnaire to ascertain demographic characteristics and the core pediatric QoL Inventory (version 4) were administered to both groups before the sessions and one month after the last training session. The data were analyzed using SPSS 20..
The mean age of the children was 10.2 and 10.5 years in the intervention and control groups, respectively. The duration of the disease was five years in both groups. Furthermore, a significant difference was seen in the mean score of the children’s QoL from their own perspectives in the physical and psychosocial domains and the total QoL score in the intervention group before and after the training (P Since family-centered empowerment interventions can determine the training- and treatment-related needs of patients and are low cost and effective, they may help parents promote their children’s self-efficacy and QoL..

Increased rates of addiction and its broad societal complications are well known. One of the most important systems that may malfunction in drug abusers is the reproductive system, and evaluating patients for this potential risk may lead to increased awareness..
Thirty 60-day-old male rats were divided into control and target groups. The target group underwent 5 mg/kg intraperitoneal injections of morphine twice a day while the control group underwent normal saline injections (at the same dosage). After 60 days, the rats were anesthetized, and after blood sampling, they underwent bilateral orchiepididymectomy. Histological and hormonal evaluations were performed on the samples..
Levels of sex hormonal features and spermatogenesis were significantly reduced in the target group compared to the control group. LH levels showed a meaningful decrease in the target group, but FSH and testosterone levels did not. On histological section analysis, mature sperm were meaningfully decreased in the target group..
Chronic use of opioids may lead to alterations in sexual features and sexual hormones. Therefore, opioids have the potential to cause infertility. These changes may result from the effect of the drugs on the hypophysis or hypothalamus, the direct effect of the drugs on the seminiferous tubules, or a combination of both. The findings suggest that public awareness about addiction may cause decreased infertility rates..

Primitive neuroectodermal tumor (PNET)/Ewing’s sarcoma (EWS) belongs to a family of neoplasms that are presumed to originate from the neuroectodermal crest. PNET/EWSs are highly aggressive malignancies that usually present in the form of bone or soft tissue masses and usually affect adolescents and young adults. Primary PNET/EWS of the kidney is very rare..
We present the case of a 32-year-old female patient with primary renal PNET/EWS diagnosed nine years and eight months earlier. The patient presented with acute flank pain in the left lumbar region, hematuria, and episodes of high body temperature of 40°C. Abdominal ultrasound (US) and subsequently performed computed tomography (CT) revealed a large renal mass of heterogenous structure. The kidney tumor had central necrotic hypodense areas and strongly peripherally enhanced solid parts on postcontrast CT images. Immunohistochemistry revealed positivity for CD99 and neuron-specific enolase (NSE). Tumor cells were negative for CD3, CD 20, chromogranin, synaptophysin, vimentin, and neurofilament. Reverse transcription polymerase change reaction (RT-PCR) revealed EWS/FL1 translocation type 2. The patient underwent nephrectomy and polychemotherapy. The follow-up nine years and eight months after the diagnosis showed no evidence of tumor..
PNET/EWS should be included in the differential diagnosis of renal tumors in symptomatic young adults. Patients with localised PNET/EWS treated with a combination of surgery and chemotherapy have an excellent chance of long-term survival, as in the case we have presented..

Context: Nocturnal enuresis or bedwetting is the most common type of urinary incontinence in children. It has significant psychological effects on both the child and the family. Enuresis nocturna is defined as the inability to hold urine during the night in children who have completed toilet training. It is termed as being “primary” if no continence has ever been achieved or “secondary if it follows at least 6 months of dry nights. The aim of this review was to assemble the pathophysiological background and general information about nocturnal enuresis.
Evidence Acquisition: This review was performed by evaluating the literature on nocturnal enuresis published between 1970 and 2015, available via PubMed and using the keywords “nocturnal enuresis,” “incontinence,” “pediatric,” “review,” and “treatment.”.
Children with nocturnal enuresis produce urine at higher rates during the night, and may have lower bladder capacities. Some children with nocturnal enuresis may also have daytime urgency, frequency, and urinary incontinence. Treatment includes aggressive treatment of accompanying constipation or urinary tract infections, behavioral changes, and medical therapy. Alarm therapy remains the first-line treatment modality for primary nocturnal enuresis. High rates of patient compliance and relapse mean that alternative treatments remain on the agenda..
Nocturnal enuresis is a common problem that has multifaceted effects on both the child and the family. Due to multiple etiologic factors, nocturnal enuresis is still not clearly defined..
