1/39. Acute retention of urine due to prolapsed ectopic ureterocele in an adult male.A case is presented of prolapsed ectopic ureterocele which produced severe urinary retention in a 31-year-old male patient. The usefulness of lumbar transcutaneous puncture is emphasized in a case associated with a non-functioning upper pole of a duplex kidney.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
2/39. Common sheath reimplantation with ureteral plication: a useful technique for the management of ectopic ureterocele.BACKGROUND: When salvaging the upper pole kidney in duplex ectopic ureterocele, primary bladder level surgery with common sheath ureteral reimplantation has the definite advantage of allowing the reconstruction of the entire collecting system through a single lower abdominal incision. However, there are several complications associated with a common sheath reimplantation in a child with a very dilated upper pole ureter, such as vesicoureteral reflux or ureterovesical stenosis. methods/RESULTS: To avoid these complications, ureteral plication over the common ureteral sheath in two children with duplex ectopic ureterocele was used. Postoperatively, neither child showed reflux or recurrent urinary tract infection and both showed a marked improvement of the upper pole collecting system. CONCLUSION: This technique allows for a simple and definitive reconstruction in cases of duplex ectopic ureterocele, particularly with dilated upper pole ureter.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
3/39. 49,XXXXY syndrome with hydronephrosis caused by intravesical ureterocele.A 1-month-old boy was referred to our hospital with right hydronephrosis. Excretory urography showed poor visualization of the right kidney and a filling defect in the bladder. Chromosomal analysis of peripheral blood revealed a karyotype of 49,XXXXY, and a diagnosis of 49,XXXXY Klinefelter s syndrome associated with hydronephrosis caused by intravesical ureterocele was made. 49,XXXXY Klinefelter s syndrome with anomalies of the urinary tract is extremely rare, and only 2 cases have been reported so far.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
4/39. Evaluation of ureterocele with Doppler sonography.ureterocele is a common disorder characterized by cystic dilatation of the terminal submucosal portion of 1 or both ureters. Conventional imaging modalities for the diagnosis of ureterocele include intravenous urography and voiding cystourethrography; gray-scale sonography, augmented by color Doppler and spectral analysis studies, can be useful in diagnosing and managing this condition as well. We describe the diagnosis of ureterocele using transvaginal gray-scale and color Doppler sonography with spectral analysis in 2 women. color Doppler sonography demonstrated urine flow into the bladder, and spectral analysis was used to measure the flow velocity. Together, these modalities can provide additional information about urinary flow dynamics, aid in implementing treatment for patients with ureterocele, and eliminate the need for invasive diagnostic procedures.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
5/39. Outcome of patients with prenatally detected duplex system ureterocele; natural history of those managed expectantly.PURPOSE: We assessed the outcome of patients treated for prenatally detected duplex system ureterocele with particular reference to those treated expectantly. MATERIALS AND methods: We reviewed the records of 52 consecutive patients treated between 1984 and 1999 with a median followup of 8 years (range 1 to 16.2). RESULTS: Of the 38 patients who underwent surgical treatment 13 subsequently required unplanned secondary procedures. A total of 14 cases satisfying currently defined criteria, including less than 10% upper renal pole function, an unobstructed lower pole (absent nonrefluxing hydroureteronephrosis), lower pole vesicoureteral reflux not exceeding grade III and unobstructed bladder outflow, were managed expectantly with a median followup of 8 years (range 1.6 to 12.8). In this group of patients prophylactic antibiotics were routinely prescribed until the completion of toilet training or age 5 years in those with persistent reflux on repeat cystography. None has required surgery or had symptoms or urinary infection. In 6 cases followup ultrasonography showed substantial resolution of upper pole hydronephrosis with a collapsed ureterocele. Furthermore, 7 of the 38 patients who underwent surgical treatment early in our series would have been treated expectantly had the current criteria been applied. CONCLUSIONS: In 14 of the 52 patients (approximately 27%) with prenatally detected duplex system ureterocele the natural history of the complaint is essentially benign within the currently available followup.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
6/39. pseudohypoaldosteronism associated with ureterocele and upper pole moiety obstruction.A 2-month-old girl was diagnosed with a febrile urinary tract infection. Subsequent studies revealed a right renal duplication anomaly with a poorly functioning upper pole moiety subtended by an intravesical ureterocele. The patient was also found to have hyperkalemia, hyponatremia, and elevated serum aldosterone. After antibiotic therapy, the urinary tract infection resolved, although the electrolyte and hormonal abnormalities persisted. At 4 months of age, a right upper pole heminephrectomy was performed. The patient's electrolyte and hormonal levels normalized. This case represents an unusual case of pseudohypoaldosteronism presenting with urinary tract infection and obstructed upper pole moiety that resolved after surgical intervention.- - - - - - - - - - ranking = 3keywords = urinary (Clic here for more details about this article) |
7/39. Unusual presentation of cecoureterocele.A three-year-old female had a nephroureterectomy for a hydronephrotic left kidney with a total duplicated collecting system. Postoperatively urinary retention developed which was found to be secondary to a previously nonobstructive cecoureterocele. A brief review of cecoureteroceles is given along with the possible cause of this unusual presentation.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
8/39. Endoscopic management of a ureterocele in complete ureteric duplication of an infant.A 2-month-old female infant with an initial symptomatic presentation of fever suffered from persistent febrile urinary tract infections and was treated with antibiotics. Further evaluation including voiding cystourethrography (VCUG), Tc-99m dimercaptosuccinic acid (DMSA) scan, intravenous urography (IVU) showed a ureterocele and hydroureteronephrosis in the upper moiety of a left duplicated kidney. Endoscopic incision of the ureterocele was successful in treating the ureterocele, urinary tract infection and salvaging the function of the upper moiety of the kidney in a 1-year follow-up visit.- - - - - - - - - - ranking = 2keywords = urinary (Clic here for more details about this article) |
9/39. Percutaneous antegrade pyelography in small infants and neonates.Percutaneous antegrade pyelography is a safe and useful alternative to retrograde pyelography in the investigation of urinary-tract malformations in the neonate or very young infant. It is preferred to arteriography in the infant with a loin mass. Satisfactory delineation of hydronephrosis or cysts is simply and directly accomplished by this method, so that more complex and less definitive investigations can often be avoided. In addition, a variety of ureteric abnormalities may be displayed.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
10/39. diagnosis of ureterocele with transvaginal sonography.We report here the case of a 49-year-old Japanese woman who presented to the clinic for uterine cervical cancer screening and who had a history of repeated cystitis. Normal imaging demonstrated no abnormalities of the genital organs; however, transvaginal ultrasound revealed ureterocele. Given the lack of ureterocele-related symptoms and the absence of hydronephrosis, the patient was followed up using repeat sonographic studies and intravenous pyelography. In conclusion, transvaginal sonography is a useful tool in the diagnosis of urinary diseases. In patients with recurring urological symptoms, it is important to check for gynecological diseases as well as urologic diseases. This can be provided well with transvaginal sonography.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
