Duplex System with Ectopic Ureter Opens into the Posterior Urethra: Case Report.

INTRODUCTION: Duplicated ureter or Duplex Collecting System is a congenital condition in which the ureteric bud, the embryological origin of the ureter, arises twice, resulting in two ureters draining a single kidney. This congenital anomaly is rare, and even rarer when the duplex system with ectopic ureter is present. This type of congenital anomaly is even more rarely diagnosed and surgically treated in adulthood. CASE REPORT: This case report presents a case of a 32-year-old male, who had a duplex collecting system with two ureters on the left side. Ectopic ureter, draining the upper pole of the left kidney, opened into the posterior urethra. In our patient, taking into account the clinical perspective, the renal tissue damaging of the upper pole which was not functional, partial nephrectomy and ureterectomy was successfully performed.

Correlation of serum and ionized calcium in patients with calcium nephrolithiasis.

INTRODUCTION: Pathogenesis of kidney stones includes many factors, whereas uroliths, as a generic term for kidney stones, are of a different composition. In pathogenesis of calcium urolithiasis hypercalcemia/hypercalciuria takes a significant place. Hypercalcemia exists when the serum calcium is of increased values, along with measurement and calculation of physiologically active calcium, when there are differences in the Ph of the blood or albumin. GOAL: the goal of this research is to determine the correlation of values of the serum (CaS) and ionized calcium (Ca++) in patients with the calcium nephrolithiasis, whom have been established not to have hyperparathyroidism and malign diseases. MATERIAL AND METHODS: the research was prospective and implemented at the Clinical Center in Banja Luka, at the Urology Clinic, in the period between 1(st) April 2012 - 1(st) January 2013 and it included 120 patients with the calcium lithiasis of the upper part of the urinary tract, divided into three age categories. Diagnosis of the calcium lithiasis of the upper part of the urinary tract was established on the basis of the ultrasonography of the urinary tract as well as native urinary tract/intravenous urography and chemical analysis of the stone in patients with spontaneous stone emission or after some of the methods for active removal of the stone. Chemical laboratory analysis of the serum and ionized calcium was done for all the patients, with 3ml of blood being taken for establishing the aforementioned parameters (1-2 ml of the serum) in vacuumed test tubes or glass tubes of capillary blood. Increased parathormone values (PHT) and history of malignity were excluding factors. RESULTS: out of the 120 patients observed, Cs(S) had the value in the reference interval with most of them, that is, in 110 patients (91.7%). Those, whose value was out of the interval, are of an older age (all above 40). Average value of this parameter amounted to 2.3017, with an average difference (the standard deviation) of 0.11391. Observing the value of Ca++, the value within the reference interval was found in 106 patients (88.3%). Out of the remaining 14 patients, only two simultaneously had the value of Ca(S) out of the permitted interval. The majority of this group consisted of older patients (a half of those whose values were outside the interval was over 60). Average value of Ca++ amounted to 1.22 mmol/L with an average difference of 0.06454. In the 2 aforementioned patients, who simultaneously had increased values of CaS and Ca++, the blood Ph was within the referential value limits, which suggests that, in line with the hyporcalcemia definition, only 2 patients with nephrolithiasis, in the total sample of 120 patients of our research sample, could have had a true hypercalcemia. CONCLUSION: the biggest number of patients with the calcium urolithiasis, who do not have hyperparathyroidism and history of malign diseases, do not have a real hypercalcemia.

Correlation of the body mass index and calcium nephrolithiasis in adult population.

INTRODUCTION: Prevalence of the kidney stones (renal calculi) increase in several countries in parallel with the increase of overweight, diabetes (type 2 diabetes) and hypertension. GOAL: The goal of our research was to evaluate the connection between the calcium nephrolithiasis and overweight, as quantified using the Body Mass Index (BMI) of the adult population, with a particular reflection on the age groups within it. MATERIAL AND METHODS: The research was prospective and it was implemented at the Clinical Center of Banja Luka, at the Urology Clinic in the period from 1(st) April 2012 to 1(st) January 2013. The trial encompassed 120 patients with calcium nephrolithiasis of the upper part of the urinary tract and 120 patients without nephrolithiasis. A group of patients with the calcium nephrolithiasis presented a working group, while a group of patients without nephrolithiasis presented a control group. The BMI obtained on the basis of bodily weight and height of the patient, where the age and sex of specific reference values of the BMI were developed by the Center for Disease Control and Prevention (CDC) were not used in the calculation of the BMI. RESULTS: Analyzing the values of the BMI in relation to age groups, where there was a statistically significant difference in the working group, whereas in the control group there was a statistically high significant difference, testing of statistical significance of the average value of the BMI was done by observed age groups of working and control group, as well as to the total sample of work and control group using the Chi-Square test and T-test for independent samples. Having observed the age group of 20-40 years, statistically significant differences have been noted at the level of risk of 10%, which confirms that there is a connection between the categories of the BMI and the group, which the patient comes from (Chi-Square test p-0.05), that is, T-test has shown that the values are different at the level of 10%, i.e. p<0.1 (p=0.073). Having observed the age group 40-60, there was no dependency between the category of the BMI and the group, that is, the differences are not statistically significant, p>0.05 (t-test p=0.314). In addition to this, the average BMI values are not significantly different, p>0.05 (t-test p=0.871). Having observed the age group of the older than 60, there was no dependency between the category of the BMI and the group, that is, the differences are not statistically significant, p>0.05 (Chi-square test p=0.167). Having observed the total sample of the working and control group, there was no dependency of the category of the BMI and the group (or urolithiasis), p>0.05 (Chi-Square test p=1.208), whereas the results of the T-test showed that there was no statistically significant difference of the arithmetic mean values of the BMI working group and control group, p>0.05 (t-test p=0.620). CONCLUSION: Overweight in younger age groups of adult population may be connected to the occurrence of calcium nephrolithiasis, thus we suggest that urolithiasis should be considered with them, as part of overweight, by which a change of living habits and the manner of food consumption could prevent this disease.

Treatment of vesicovaginal fistulas: an experience of 30 cases.

BACKGROUND: Vesicovaginal fistulas (VVF) are rare. In developed countries, the majority of vesicovaginal fistulas occur after gynecological procedures such as total hysterectomies. OBJECTIVE: The evaluation of successfulness of VVF surgical repairs with transvesical, transvaginal and transabdominal approach with omental flap in 30 patients. METHODS: This is a retrospective study of patients suffering from VVF who were treated with transvesical, transvaginal and transabdominal approach with omental flap from July 2004 until December 2012. During that period, 30 patients with VVF underwent a surgical treatment at the Clinic of Urology, University Clinical Center of Banjaluka. Ten patients had previously taken radiotherapy due to cervical cancer and as a consequence of that VVF developed. In 19 patients, fistula occurred after total hysterectomy, and in one patient it occurred after the cesarean section. In six patients, primary surgical repair was performed by supravesical urinary diversion. The average size of fistula was 14 mm. RESULTS: The primary repair of VVF was successful in 75.00% of patients (18/24). In six patients (25.00%), it was not successful, and they remained incontinent. The successfulness of primary repairs with transvaginal and transabdominal approach with the use of omental flap was 100%, and with transvesical approach, it was 68.42%. The secondary surgical repair was performed in the remaining five patients, and it was successful in two patients (40.00%), but cumulatively speaking, the successfulness was 83.33% (20/24). In the secondary repair, the successfulness of transvaginal approach was 50.00%, and of transvesical one, it was 33.33%. Three patients underwent the tertiary surgical repair and its successfulness was 0%, and the approaches were transvaginal in one patient, transvesical in another one, and combination of transvesical with additional stitches with transvaginal approach in the third patient. When the surgical repair was undertaken for the fourth time, the successfulness was 100%. In two patients, the approach was transabdominal with interposition of omental flap, and in one patient, the approach was transvaginal. When everything is taken into consideration, 23 out of 24 patients had a successful closure of fistula, and we lost track of one patient whose primary repair was unsuccessful. CONCLUSION: The selective approach to the repair of VVF mostly depends on the surgeons skill and experience. The successfulness of the repair depends on the excision of the pathological tissue, the closure of fistula in a well vascularized tissue and on urine drainage.
