Malignancy is a common complication after renal transplantation. However, limited data are available on post-transplant malignancy in living kidney transplantation. Therefore, we made a plan to evaluate the incidence and types of malignancies, association with the main risk factors and patient survival in a large population of living kidney transplantation. We conducted a large retrospective multicenter study on 12525 renal recipients, accounting for up to 59% of all kidney transplantation in Iran during 22 years follow up period. All information was collected from observation of individual notes or computerized records for transplant patients. Two hundred and sixty-six biopsy-proven malignancies were collected from 16 Transplant Centers in Iran; 26 different type of malignancy categorized in 5 groups were detected. The mean age of patients was 46.2±12.9 years, mean age at tumor diagnosis was 50.8±13.2 years and average time between transplantation and detection of malignancy was 50.0±48.4 months. Overall tumor incidence in recipients was 2%. Kaposis' sarcoma was the most common type of tumor. The overall mean survival time was 117.1 months (95% CI: 104.9-129.3). In multivariate analysis, the only independent risk factor associated with mortality was type of malignancy. This study revealed the lowest malignancy incidence in living unrelated kidney transplantation.
Background:The treatment of urethral stricture in female patients is through dilatation of the urethra by tubes of increasing diameter. There are two main methods: intermittent dilatation and on demand dilatation.Objectives:The main aim of this study was to compare the results of these two methods, and to determine the best one.Patients and Methods:In this clinical trial study, we reviewed the documents of women diagnosed with urethral stricture, who came to the Baqiyatallah Clinic from 2007 and 2012. According to the method of dilatation, the patients were divided into two groups: intermittent dilatation and on demand dilatation. Patients’ data were then collected and analyzed.Results:Eighty-six patients were enrolled in the study. The mean age of the participants was 48.13 years (between 44 and 79 years). The mean urinary residual and maximum urinary flow speed changes, before and after on demand dilatation, were higher than in the intermittent method.Conclusions:For treating urethral stricture, on demand urethral dilatation is more effective than intermittent dilatation.
Serum level of HbA1c could not be used as a predictor for the development of POAF.
BackgroundStress Urinary Incontinence (SUI) is one of the most reported health dilemmas of women suffering from lower urinary tract symptoms.AimTo determine the relation between hysterectomy and severity of female SUI using Valsalva Leak Point Pressure (VLPP).MethodsThis case-control study was conducted at a public urology clinic in Tehran in 2015. The study population was all female with SUI complaints who visited the clinic during 2015. We compared Valsalva leak point pressure in two groups of female SUI patients with and without hysterectomy history. The inclusion criteria were: not taking any alpha-blocker or anti-cholinergic medicines two weeks prior to the urodynamic test as well as no history of pelvic surgery or cesarean delivery in their lifetime. All qualified patients were invited to participate in the study randomly, and among them, 120 qualified patients agreed to participate by filling out the informed consent form. Data was gathered through direct interview, and double checked by patients’ medical records. All the study variables including age, BMI, delivery number, hysterectomy and UTI history were entered and analyzed by estimating ordered logistic regression and by using Stata14.1 software.ResultsThe mean of VLPP was 70.17 cmH2O in the group with hysterectomy history, and 94.55 cmH2O in those without hysterectomy history. The difference of VLPP pressure between the two studied groups were significant (p<0.05), even after control of confounding variables. Also, the odds of severe SUI among hysterectomy group patients was 6.3 times more than no hysterectomy (OR=6.32, p<0.001).ConclusionsOur study confirms significant relation between hysterectomy and SUI severity measured by Valsalva leak point pressure. Hysterectomy patients are more likely to suffer from more severe grades of SUI.
Introduction: Uric acid is one of the most significant uremic toxins accumulating in chronic renal failure patients treated with standard dialysis. Its clearance has not any exact relation with urea and creatinine clearance. Objectives: The aim of this study was to investigate the relationship between adequacy of dialysis and serum level of uric acid in dialysis patients of some dialysis centers in Iran. Patients and Methods: In this study 1271 hemodialysis patients who have been treated for more than 3 months were evaluated. Their information and examinations from their files in all over the country were gathered and analyzed using SPSS versin18.0. Results: In this study, a significant relationship between dialysis duration and serum level of uric acid was not detected, however, a significant relationship between patients Kt/V and uric acid (R=0.43, P=0.029) was seen. Patients who had higher adequacy of dialysis had a higher level of plasma uric acid. Conclusion: For better controlling of plasma uric acid level of hemodialysis patients, increasing of the adequacy of dialysis or its duration is not effective. Other modalities of decreasing of serum uric acid like, changing diet or lifestyle or medical therapy may be necessary.
Objective: To present our experience with laparoscopic management of symptomatic simple renal cysts. Methods: From April 2004 to November 2006, 21 patients (10 men; 11 women) underwent laparoscopic decortication for simple renal cysts at our department and were included in the analysis. All procedures were carried out by one surgeon using a transperitoneal approach. Patients underwent radiological follow-up with computerized tomography and/or ultrasonography. Procedural success was defined as no recurrence of the cyst and complete pain relief. Symptomatic success was defined as a significant pain decrease. Results: All 21 procedures were completed laparoscopically, without major complications or conversion to open surgery. Estimated mean blood loss during surgery was about 50 mL. Patients were hospitalized for a mean of 1.9 Ϯ 1.1 (range: 1-5) days. Age of the patients and size and location of the cysts, had no relationship with the duration of operation as well as the length of hospital stay (P > 0.05). Patients who experienced complete pain relief had significantly larger cyst sizes compared with patients with a partial pain decrease (7.3 Ϯ 1.1 vs 9.1 Ϯ 2.0, respectively; P = 0.023, F = 0.606). All patients had negative cytological and pathological findings for malignancy or any other abnormalities. At 16.6 months of mean follow up, none of the patients reported symptomatic and/or radiologic failure. Conclusions: Laparoscopic transperitoneal decortication represents an effective and safe treatment option in the management of symptomatic renal cysts.
Aim. In this study we report our experience with microhematuria and its relation with bladder tumors in Iranian women. Materials and Methods. Overall 249 women were evaluated. Microscopic hematuria was defined as three or more red blood cells per high-power field on at least two different occasions. Patients with a history of gross hematuria or coagulation disorders, having organic diseases, urinary stones, urinary tract infections, nephrological diseases, and local lesions such as urethral caruncle were excluded from the study population. Final diagnosis of malignant tumors was done with cystoscopy and biopsy specimen pathological assessment in all cases. Results. Age for the study population was 49.7 ± 11.8 years. 95 (38%) of patients were identified during routine check up and presenting symptoms in other patients were frequency, dysuria, stress urge incontinence, urge incontinence, feeling of incomplete urine emptying, and flunk pain, respectively. Finally, 7 (2.8%) of study subjects were confirmed as having bladder tumors. One of tumor cases was diagnosed 24 months after initial assessments. Patients with bladder tumor were significantly older; more frequently had diverticulum in their bladder wall (P < .05). Conclusion. Female microscopic hematuria is relevant and deserves evaluations, especially in elderly patients. Patients whose reason for microhematuria would not be diagnosed at the initial evaluations should be followed.
