Primary renal carcinoid natural history of the disease for ten years: case report. (1/58)

BACKGROUND: Primary renal carcinoid is extremely rare and there are few reports on the natural history of the disease. CASE PRESENTATION: A 68-year-old male with a right renal mass who lost to follow-up for ten years has been presented. His only complaint was a mild flank pain. Upon admission to the hospital for his renal mass, he underwent a right radical nephrectomy and pathological examination revealed the diagnosis of primary renal carcinoid. CONCLUSIONS: In light of the presented case, primary renal carcinoma may have a prolonged natural history with no distant metastasis and any change in the quality of life of the patient.  (+info)

Hydronephrosis by an aberrant renal artery: a case report. (2/58)

Ureteropelvic junction obstruction is usually intrinsic and is most common in children. Aberrant renal arteries are present in about 30% of individuals. Aberrant renal arteries to the inferior pole cross anteriorly to the ureter and may cause hydronephrosis. To the best of our knowledge, although there are some papers about aberrant renal arteries producing ureteropelvic junction obstruction, there is no report of a case which is diagnosed by the new modalities, such as computed tomography angiogram (CTA) or magnetic resonance angiogram (MRA). We describe a 36-year-old woman with right hydronephrosis. Kidney ultrasonogram and excretory urogram revealed right hydronephrosis. CTA and MRA clearly displayed an aberrant renal artery and hydronephrosis. The patient underwent surgical exploration. For the evaluation of hydronephrosis by an aberrant renal artery, use of CTA and MRA is advocated.  (+info)

Correlation of radiological and clinical features of metanephric neoplasms in adults. (3/58)

The main objective was to determine the clinical and radiological features of metanephric neoplasms. The tumors were diagnosed on histopathological examination. The clinical data and imaging features were retrospectively analyzed. Between 1998 and 2003, 3 patients underwent radical nephrectomy for renal masses turning out as metanephric neoplasms on histopathology. Two of these tumors were metanephric adenoma (MA) and one was metanephric adenofibroma (MAF). Clinical and radiological features were reviewed. All patients were adult females who presented with flank pain. Tumor was detected on screening ultrasound as a hyperechoic lesion. In all cases CT showed a hyper-attenuating exophytic lesion with cystic areas that enhanced with IV contrast. Based on combination of clinical and imaging features it may be possible to prospectively identify metanephric neoplasms and thus avoid unnecessary radical nephrectomy in favor of conservative surgery.  (+info)

Duration of symptoms and follow-up patterns of patients discharged from the emergency department after presenting with abdominal or flank pain. (4/58)

BACKGROUND: Little is known about the duration of symptoms and follow-up patterns of patients seen in emergency departments for abdominal or flank pain. OBJECTIVE: We aimed to measure the duration of symptoms and follow-up rate of patients discharged home from the emergency department after presenting with non-traumatic abdominal or flank pain. METHODS: We conducted a single-centre, prospective descriptive study of adult patients who presented to our emergency department with non-traumatic abdominal or flank pain and were discharged from the emergency department. We gathered clinical data during the index emergency department visit and conducted telephone interviews of subjects 2-5 weeks later. RESULTS: We reached 63 of 90 subjects (70%). The median duration of pain was 3 days after the emergency department visit. During the follow-up period, only 41% had followed-up with their family physician or primary care provider, although an additional 21% had planned to. Persistence of symptoms was common in the 37% of subjects who did not follow-up. CONCLUSION: Of subjects discharged from the emergency department after visits for non-traumatic abdominal or flank pain, most improve within several days. Fewer than half follow-up with a family practitioner or a primary care provider. Emergency department revisits are uncommon and often for unrelated problems.  (+info)

Clinical and magnetic resonance imaging features of cricket bowler's side strain. (5/58)

The clinical features of 10 cases of lateral trunk muscle injury in first class cricket pace bowlers are described. Typically the injury occurs during a single delivery, is associated with considerable pain, and prevents the bowler from continuing. The clinical picture is typical of a muscular or musculotendinous injury. The most consistent clinical tests were focal tenderness on palpation and pain with resisted side flexion towards the painful side. The magnetic resonance image in 70% of cases was consistent with an injury to the internal oblique, the external oblique, or the transversalis muscles at or near their attachments to one or more of the lowest four ribs. The injury occurs on the non-bowling arm side. Recovery can be prolonged. The injury was a recurrence in six of the 10 cases. The biomechanics of the injury are not yet understood.  (+info)

Left flank pain as the sole manifestation of acute pancreatitis: a report of a case with an initial misdiagnosis. (6/58)

Acute pancreatitis is not an uncommon disease in an emergency department (ED). It manifests as upper abdominal pain, sometimes with radiation of pain to the back and flank region. Isolated left flank pain being the sole manifestation of acute pancreatitis is very rare and not previously identified in the literature. In this report, we present a case of acute pancreatitis presenting solely with left flank pain. Having negative findings on an ultrasound initially, she was misdiagnosed as having possible "acute pyelonephritis or other renal diseases". A second radiographic evaluation with computed tomography showed pancreatitis in the tail with abnormal fluid collected extending to the left peri-renal space. We performed a literature review and discussed this rare occurrence of acute pancreatitis. We also discussed the clinical pitfalls in this case.  (+info)

Prospective validation of a current algorithm including bedside US performed by emergency physicians for patients with acute flank pain suspected for renal colic. (7/58)

OBJECTIVE: The purpose of this study was to validate an algorithm recommended by current literature for the patients with acute flank pain and evaluate the validity of bedside ultrasonography (US) performed by emergency physicians (EP) as a part of this algorithm. MATERIALS AND METHODS: This prospective validation study was carried out over a 5 month period in a tertiary care hospital adult emergency department (ED) with annual attendance of 55,000. Adult patients presenting to the ED with unilateral acute flank pain during the study period were enrolled into the study consecutively. Oral consent was obtained after the protocol was briefly explained to the patient and before the administration of analgesia. A protocol form was recorded for each patient enrolled into the study, and patients were followed up under the guidance of a previously designated algorithm in the ED. Data were analysed with SPSS software. The chi2 test was used to compare the dichotomised data of patients, diagnosed with and without stones, and to select the significant parameters to be used in the logistic regression. RESULTS: Of the 227 patients enrolled, 176 were proven to have urinary tract stones. There were 122 patients discharged from ED without further investigation except urinalysis and bedside US. Of these 122 directly discharged patients, 99 had a urinary stone, and the others did not have a life threatening disorder. Four of the 227 patients were admitted to the hospital. The remaining 51 patients did not have stones detected, and their pain subsided. Having a previous history of stones, radiation of pain to the groin, accompanying nausea, and detection of pelvicalyceal dilatation using bedside US performed by the EPs were found to be the most significant parameters in determining urinary stones in logistic regression analysis. Sensitivity and specificity of these parameters were: previous history of stones 59% and 66%, radiating pain to the groin 68% and 49%, nausea 71% and 51%, and detection of pelvicalyceal dilatation by bedside US 81% and 37%. CONCLUSION: Bedside US performed by EPs could be used safely in the evaluation of patients with acute flank pain as a part of a clinical algorithm. Previous history of urinary stones, radiation of pain to the groin, accompanying nausea. and detection of pelvicalyceal dilatation are major parameters and symptoms of urinary stone disease, and could be used in the algorithms.  (+info)

Successful renal transcatheter arterial embolization in three patients with symptomatic hydronephrosis due to ureteral obstruction. (8/58)

BACKGROUND: Conventional treatments for symptomatic enlargement of a nonfunctional hydronephrotic kidney caused by obstructive uropathy include surgical treatments. METHODS: Patients included a 67-year-old woman whose obstruction was caused by a lower urinary tract stone complicating spinal tuberculosis (patient 1); a 52-year-old man with compressive complete congenital obstruction crossing the ureteropelvic junction from an aberrant renal artery (patient 2); and a 19-year-old woman with essentially complete idiopathic congenital obstruction at the ureteropelvic junction (patient 3), who required antibiotics for pyelonephritis before embolization. The renal artery was embolized using platinum microcoils. RESULTS: Although the sensation of abdominal fullness diminished within approximately two week after TAE, it took one to two years until the embolized kidney size shrank from 1377+/-634 cm3 (range, 829 to 2072) to 43+/-46 cm3 (42 to 94) by the evaluation of computed tomography. Fever after embolization persisted for 5 days in patient 1, 3 in patient 2, and 9 in patient 3. Flank pain resolved within 5 days in all. Pyelonephritis and complications of treatment have not occurred. CONCLUSION: Embolization for this indication was safe and effective.  (+info)
