1/158. Ureteral compromise after laparoscopic Burch colpopexy.ureteral obstruction occurred in two patients after laparoscopic Burch cystourethropexy. Both women experienced right flank pain and right hydronephrosis. cystoscopy revealed transmural passage of suture anterior and lateral to the ureteral orifice on the right side. One patient was managed by suprapubic cystoscopy to release the suture; the other was managed by preperitoneal laparoscopy to release suture at the bladder neck. In both patients efflux of urine was seen immediately from the ureteral orifice after suture release. Ultrasound confirmed prompt resolution of hydronephrosis. cystoscopy with confirmation of patent ureters should be performed after every case of retropubic cystourethropexy. Retrograde rigid cystoscopy may not afford adequate access to remove transmural sutures. Placement of sutures at the bladder neck from medial to lateral may avoid entrapment of the intramural portion of ureter.

2/158. Ureterocystoplasty in a patient with a single kidney.Ureterocystoplasty (UCP) has now been widely used for bladder augmentation, with and without unilateral nephrectomy. Many techniques have been described to incorporate portions of the upper renal tract, but none have yet described UCP in a child with unilateral renal agenesis.- - - - - - - - - - ranking = 0.74615371149667keywords = upper (Clic here for more details about this article) |
3/158. De novo direct duplication of 15q15-->q24 in a newborn boy with mild manifestations.Duplication of distal 15q results in a recognizable clinical phenotype. We report here on a 25-day-old boy with a de novo interstitial duplication of chromosome region 15q15-q24. The manifestations in this patient are milder than those of previously described patients and include minor facial anomalies, velopharyngeal insufficiency, branchial cleft cyst, and hydronephrosis. fluorescence in situ hybridization (FISH) using a chromosome 15 painting probe confirmed that the extra material is of chromosome 15 origin. Further analysis with the SNRPN probe demonstrated that the duplication is telomeric to the Prader-Willi/angelman syndrome critical region. This case delineates a broader spectrum for patients with duplication 15q syndrome.- - - - - - - - - - ranking = 1keywords = pain (Clic here for more details about this article) |
4/158. Poorly differentiated sarcoma of the prostate causing obstructive acute renal failure: a case report.A 12-year-old boy presented to the Naha Municipal Hospital complaining of back pain. After intravenous pyelography, computed tomography, magnetic resonance imaging, ultrasonography and biopsy, he was suspected to have sarcoma of the prostate and was referred to the University of the Ryukyus Hospital. Acute renal failure of the post renal type was evident, accompanied by minimal hydronephrosis. Emergency hemodialysis and right ureterostomy were performed, as was a transurethral prostate biopsy. The specimen showed a poorly differentiated sarcoma not otherwise classifiable. After recovery from surgery, chemotherapy was attempted over 2 months, but the patient died of tumor 250 days after admission.- - - - - - - - - - ranking = 1.0584702691434keywords = pain, back (Clic here for more details about this article) |
5/158. Geriatric ureteropelvic junction obstruction: the possible role of an arteriosclerotic lower pole branch of renal artery: report of two cases.An 83-year-old woman presented with left flank pain and high grade fever. After left ureteral catheterization and intensive chemotherapy with hemoperfusion, surgical exploration revealed the lower pole branches of the renal vessels were obstructing the ureteropelvic junction (UPJ), and dissection of the vessels released the obstruction. An 82-year-old man presented with right flank pain. angiography demonstrated UPJ obstruction caused by the lower pole branch of the renal artery. Arterial dissection with dismembered pyeloplasty resulted in improvement of obstruction. In both cases, the patients had a long history of hypertension with mild to severe arteriosclerosis. arteriosclerosis associated with fixation of the UPJ, may be one of the important factors leading to progressive hydronephrosis in geriatric patients.- - - - - - - - - - ranking = 2keywords = pain (Clic here for more details about this article) |
6/158. Cloacal outlet obstruction with an ectopic ureter.Cloacal malformation occurs in approximately 1 in 50,000 live female births. Prenatal ultrasound may lead to the diagnosis in selected cases. We report an unusual case of prenatally detected single-system hydronephrosis with a nonvisible bladder and worsening oligohydramnios. Labor was induced at 35 weeks' estimated gestational age. On physical examination, a single perineal opening was noted consistent with cloaca. endoscopy revealed an obstructed ectopic ureter at the level of the sphincter, an undeveloped bladder and vagina, and a fistula to the rectum. A low loop cutaneous ureterostomy and right upper quadrant loop colostomy were performed. The absence of a typical fluid-filled pelvic structure may confound the prenatal diagnosis of cloaca.- - - - - - - - - - ranking = 0.74615371149667keywords = upper (Clic here for more details about this article) |
7/158. The appendix as right ureteral substitute in children.PURPOSE: The appendix has occasionally been used to replace sections of the right ureter. We reviewed the literature of the last 25 years on the use of the appendix as right ureteral replacement and report our experience with right ureteral substitution using the appendix. MATERIALS AND methods: We retrospectively reviewed the charts of 3 children who underwent appendiceal replacement of the right ureter. The appendix replaced the upper third of the ureter and the lower ureter in 1 and 2 cases, respectively. RESULTS: Followups of 4, 7 and 15 years, respectively, demonstrated that the appendix transports urine satisfactorily and permits renal function to be maintained with no evidence of obstruction. CONCLUSIONS: We believe that our small series supports the use of the appendix as a right ureteral substitute in select cases.- - - - - - - - - - ranking = 0.74615371149667keywords = upper (Clic here for more details about this article) |
8/158. milk of calcium in the inferior calyx of a hydronephrotic kidney in a tetraplegic patient - a diagnosis to be made before scheduling for extracorporeal shock wave lithotripsy.STUDY DESIGN: A Case Report of renal milk of calcium in a tetraplegic subject. OBJECTIVES: To increase the awareness of renal milk of calcium in spinal cord injury (SCI) physicians. Renal milk of calcium contains a colloidal suspension of calcium crystals. Since upright views of the kidneys are not performed in tetraplegic subjects, the renal milk of calcium may be misinterpreted as renal lithiasis by routine radiography taken in supine position. SETTING: Regional spinal injuries Centre, Southport, england. METHOD: In a 41-year-old male with traumatic tetraplegia, X-ray of abdomen in supine position showed multiple opacities in the region of the left kidney. These radio opaque shadows were interpreted as renal calculi. Subsequently, computed tomography (CT) of the kidneys was performed. RESULTS: CT confirmed the presence of calculi in the mid-polar calyx. However, the density situated in the inferior calyx of the hydronephrotic left kidney exhibited a horizontal upper edge. This specific radiological finding as observed in the CT of kidneys, provided the clue to the presence of milk of calcium in the inferior calyx of the hydronephrotic left kidney. CONCLUSION: As plain film of the abdomen in standing position is not performed in SCI patients, physicians caring for SCI patients should have a high index of suspicion for renal milk of calcium. Prompt diagnosis of renal milk of calcium will help to avoid unnecessary surgery, or extracorporeal shock wave lithotripsy.- - - - - - - - - - ranking = 0.74615371149667keywords = upper (Clic here for more details about this article) |
9/158. Zonisamide - induced urinary lithiasis in patients with intractable epilepsy.We report here three patients with intractable epilepsy who developed urinary lithiasis during zonisamide (ZNS) treatment. abdominal pain due to left-sided hydronephrosis was the initial symptom in the first patient, and it was resolved after the excretion of a stone. The second patient, who had no specific symptoms, was found to have a thick sludge of calcium phosphate in the bladder when he suffered from aspiration pneumonia and dehydration. The third patient, who had a history of recurrent urinary obstruction, was also found to have a thick sludge of calcium oxalate in the bladder. The urinalysis of the three patients revealed alkaline urine and hypercalciuria. Although their urinary lithiasis was resolved by discontinuation of ZNS and supportive therapy, routine examination of urine parameters such as pH and sediments, and daily urine-output checks are thought to be necessary during treatment with ZNS, especially for patients who are bedridden for a long time and receive multiple antiepileptic drugs.- - - - - - - - - - ranking = 1keywords = pain (Clic here for more details about this article) |
10/158. Functional urinary tract obstruction developing in fetuses with isolated gastroschisis.OBJECTIVE: To evaluate the frequency and natural history of urinary tract abnormalities developing in fetuses presenting with initially isolated gastroschisis. methods: Serial ultrasounds were performed prospectively on fetuses identified by our prenatal diagnosis program as having a gastroschisis. When abnormalities in the urinary tract were identified prenatally, newborns were evaluated by a pediatric urologist. RESULTS: Over a 1-year period four out of 12 fetuses with gastroschisis developed deformations of the urinary tract. In three fetuses the bladder herniated through the abdominal wall defect. Two also had upper tract dilatation. A fourth fetus developed bilateral hydronephrosis with a normally situated bladder. Once the gastroschisis was repaired none of the newborns had evidence of structural obstruction of the urinary tract, however, hydronephrosis with or without reflux persisted for several months. CONCLUSIONS: Deformations of the fetal urinary tract can develop secondary to gastroschisis. They do not appear to represent separate malformations and evaluation with fetal karyotyping may not be indicated. When hydronephrosis is present ongoing urologic evaluation of the neonate is indicated.- - - - - - - - - - ranking = 0.74615371149667keywords = upper (Clic here for more details about this article) |
