Inverted papilloma of the renal pelvis associated with renal cell carcinoma: a case report.

Twenty-one cases of inverted papilloma of the renal pelvis have been described in the literature. A 71-year-old man was admitted to our hospital to examine a right renal mass. We diagnosed a right renal tumor on the basis of the findings from excretory urogram (IVP), computerized tomography (CT) and magnetic resonance imaging (MRI). Surgical material revealed an inverted papilloma in the renal pelvis. We report on the first case of an invested papilloma of the renal pelvis associated with renal cell carcinoma.

[Inflammatory myofibroblastic tumor of the renal pelvis].

Inflammatory myofibroblastic tumor (IMT) of the genitourinary tract is rare and has been classified into separate groups based on their anatomical site and postulated aetiology. Herein, we present a case of IMT of the renal pelvis. A 44-year-old man presented with gross hematuria. Abdominal computed tomography (CT) and magnetic resonance imaging (MRI) revealed a tumor of the left renal pelvis. Under the diagnosis of left renal pelvic tumor, he underwent left nephrectomy and ureterectomy. Microscopic examination revealed fascicular spindle cell proliferation in an oedematous myxoid background with an infiltrate of plasma cells. The spindle cells were strongly positive for smooth muscle actin (SMA) and vimentin, and negative for desmin and anaplastic lymphoma kinase (ALK). Diagnosis of the lesion was IMT of the renal pelvis.

[Diagnosis and treatment of gluteal muscle contracture associated with unequal leg length caused by pelvis obliquity].

OBJECTIVE: To investigate the pathogenesis, diagnosis, and treatment of the gluteal muscle contracture associated with an unequal leg length caused by the pelvis obliquity (GMC-PO). METHODS: The retrospective analysis was made on the clinical features and the follow-up results in 132 patients who had been admitted from January 1990 to December 2004 for GMC-PO. Among them, 73 were male and 59 were female with a range in age from 5 to 26 years (average, 11 yr). All the patients were characterized by unsymmetrical contracture of the gluteal muscles, including unilateral and bilateral contracture. Of the patients, 89 had a clear limping and 78 had a clearly-unequal leg length. The X-ray examination revealed pelvis obliquity in 97 cases and an increased angle of the femur neck in 11 cases. The arc longitudinal incision was made into the posterolateral area nearby the greater trochanter and then lysis of the gluteal muscles was performed, combined with the skin traction of both legs and exercise training. RESULTS: Of the 132 patients with unequal gluteal muscle contracture before operation, 13 had a relative length difference of 0.5-1.5 cm between the 2 legs, 1 had a difference of 3.0 cm, and the remaining 118 patients had an equal leg length. Excellent and good results were achieved in 118 and 13 patients, respectively after the surgical release of the gluteal muscle contracture by the arc longitudinal incision into the posterolateral area nearby the greater trochanter, combined with postoperative skin traction and functional exercises. Only 1 patient had a poor result. The follow-up for 3 months to 14 years showed that the cure rate was as high as 99.2%. CONCLUSION: The gluteal muscle contracture associated with an unequal leg length caused by the pelvis obliquity is a result of the unequal gluteal muscle contracture between the 2 hips and it can be cured with a comprehensive therapeutic method including the surgical release of the gluteal muscle contracture by the are longitudinal incision into the posterolateral area nearby the greater trochanter, and postoperative skin traction as well as the functional exercise.

[Tubulovillous adenocarcinoma of the renal pelvis. Case report].

OBJECTIVE: To present a case of tubulovillous renal pelvis adenocarcinoma. METHODS/RESULTS: An 81 year-old patient presented at Emergency Department with sepsis. CT scan showed a staghorn calculus with signs suggestive of pyonefrosis. A nephrectomy was performed and pathological exam revealed tubulovillous renal pelvis adenocarcinoma. CONCLUSIONS: Renal pelvis adenocarcinoma is a rare disease. It is usually accompanied by chronic urinary infections, on inflammatory state and staghorn calculi. The best therapeutic option is nephrectomy and the prognosis is poor.

[Predicting the outcome of labor in women with contracted pelvis].

The authors suggest that the coefficient, representing the ratio between the sizes of the small pelvis section and fetal head section, be used for the prediction of labor outcome for the fetus in women with a contracted pelvis. When the coefficient values K1-K4 were lower than 1.32, 1.35, 0.68, and 0.79, more than 90% of the newborns developed signs of cerebral circulation disorders, this prompting the use of cesarean section for this group of pregnant women. Timely correction of the policy of labor management with due consideration for the anatomical features of the pelvis helped reduce the perinatal mortality in multigravidae to 5/1000, mainly at the expense of carrying out planned cesarean section and monitoring in labor.

[Transitional cell carcinoma of the renal pelvis in a woman discovered at childbirth].

We report a case of transitional cell carcinoma of a renal pelvis in a woman discovered after childbirth. A 38-year-old woman, who delivered an immature male infant in cesarean section 29 days prior to hospitalization, was admitted complaining of asymptomatic gross hematuria. Excretory urography and retrograde pyelography showed a filling defect of the right renal pelvis, Spontaneous urine cytology indicated class 5. Renal computed tomographic scan demonstrated a mass lesion in the right kidney. Right total nephroureterectomy and partial cystectomy was performed for diagnosis and treatment. Pathological diagnosis was papillary transitional cell carcinoma (grade 2). This is the first case of transitional cell carcinoma of the renal pelvis occurring in a childbearing woman in Japan.

[Diagnosis of kidney pelvis cancer].

The new imaging procedures should improve the preoperative assessment of patients with renal pelvis carcinoma. At the Department of Urology, University of Freiburg from 1976-1986 48 patients with renal pelvis carcinoma were treated. 92% of tumors (69% looked like renal pelvis carcinoma preoperatively, 23% like kidney tumors without histological determination) were detected preoperatively. Advanced tumor stages (T4N+M1) (21%) were diagnosed correctly in 7/10 cases preoperatively and have a poor prognosis.

[A case of emphysematous pyelonephritis with septic shock recovered by transurethral drainage of pelvis].

A case of emphysematous pyelonephritis with septic shock was present in a 58-year-old diabetic woman. The spontaneous production of gas was present within the right renal pelvis in kidney-ureter-bladder X-ray. The patient's condition deteriorated rapidly after admission, became complicated with acute renal failure, disseminated intravascular coagulation and acute respiratory failure. Transurethral drainage of the pelvis using a 6 Fr. UPJ occlusion balloon catheter and endotracheal intubation with respiratory assistance were performed as a life-saving procedure. The optimal therapy with surgical or conservative approach for such a severe condition is discussed. The use of transurethral drainage of pelvis as a non-invasive treatment is suggested.

[The primary mucinous adenocarcinoma of renal pelvis: a case report].

A case of primary mucinous adenocarcinoma of the renal pelvis is reported. A 55-year-old man visited our clinic with lumbar pain. He had a history of left renal stone and had left partial nephrectomy four years previously. Physical examination revealed a hard, child-head-sized, unmovable and uneven tumor in the left side of the abdomen. Intravenous pyelography revealed the non-functioning left kidney with calcification, in which hydronephrosis was detected by computed tomography. In transabdominal sonography a huge mass with mixed echo pattern was observed. Aspiration biopsy under interventional ultrasound was performed, aspirating yellow-white semi-transparent mucinous substance, which was highly suspicious of malignancy by cytology. He died 74 days after the first admission. Autopsy revealed primary mucinous adenocarcinoma of the renal pelvis. This was thought to be the 14th case of primary mucinous adenocarcinoma of the renal pelvis reported in the Japanese literature.

[Spontaneous rupture of the renal pelvis: a case report].

A 63-year-old man admitted to our hospital with severe pain in his right flank on June 4, 1987. After admission, his pain increased progressively and he complained of tenderness from the right flank to the right lower quadrant. Computerized tomography and intravenous pyelography demonstrated spontaneous rupture of the right renal pelvis. A retrograde ureteral catheter was indwelling into the right renal pelvis. Because extravasation had disappeared on the retrograde pyelogram, the Catheter was withdrawn after 12 days. After removal of the ureteral catheter, he did not complain of pain. The 42 patients with spontaneous rupture of the renal pelvis reported in the Japanese literature and our one case were discussed.

Extrarenal pelvis mimicking obstructive uropathy in nine years of serial bone scintigraphies.

A woman who underwent mastectomy for left breast carcinoma has been followed-up yearly with bone scintigraphy using Tc-99m diphosphonate compounds for nine years. In the bone images of the initial three years (first, second, and third years postmastectomy), radiotracer accumulation in the right renal upper collecting system had been interpreted as obstructive uropathy. Then the patient underwent initial (third year postmastectomy) and repeat (fifth year postmastectomy) intravenous contrast pyelography (IVP), which revealed an extrarenal pelvis with no significant interval changes. The fourth and fifth bone scintigraphs and the subsequent four consecutive bone scintigraphs showed the same pattern radiotracer retention in the right renal collecting system. Thus, while interpretation of an accumulation of radiotracer in the upper renal collecting systems on a single bone scintigraphy may provide difficulty in making a differential diagnosis between obstructive uropathy and extrarenal pelvis, IVP is important for definitive diagnosis. Alternatively, a review of the previous consecutive bone studies, if available, may also aid in this differentiation, since obstructive uropathy may manifest as progressive renal dysfunction, while extrarenal pelvis may have the same pattern of radiotracer accumulation in the collecting system persistently.

[A case of a primary localized amyloidosis (amyloid tumor) of the renal pelvis and ureter].

A 62-year-old woman complaining of asymptomatic hematuria was hospitalized. Although a cytologic examination of the urine was negative, abnormal findings in the right renal pelvis by DIP, RP and CT led us to suspect a pelvic tumor, and a right nephroureterotomy was performed. Light microscopy revealed deposits of amorphous, eosinophilic material in the pelvis and proximal portion of upper ureter, however tumor cells were not found. Electron microscopy revealed that these materials were aggregates of linear, non-branching fibrils, measuring about 8 nm in diameter. Histochemically, these were seen to be consistent with amyloid, producing an apple-orange birefringence with Congo red staining under a polarized light. Alkali Congo red staining after pretreatment of KMnO4 demonstrate that this amyloid protein was composed largely of AA protein in addition to lesser amounts of non-AA protein, and a primary localized amyloidosis (amyloid tumor) was diagnosed. A clinicopathologic study that was performed on 12 cases of primary localized amyloidosis of the pelvis, including our case, also is reported.

[Squamous cell carcinoma of renal pelvis: a case report and review of the Japanese literature].

Squamous cell carcinoma of renal pelvis is relatively rare and its prognosis is very poor. A 72-year-old man was introduced to our institute because of macroscopic hematuria. He had no history of urolithiasis or urinary tract infection. Excretory urography showed a nonfunctioning right kidney. Cytologic examination of urine was positive for malignant cell from squamous cell carcinoma. Preoperative diagnosis was made as right renal pelvic tumor, but it appeared to be renal tumor on the roentgenogram. Right radical nephrectomy and transurethral ureterectomy was performed. Radiation therapy was done after operation. Pathological diagnosis was squamous cell carcinoma of renal pelvis extensively infiltrating to the renal parenchyma. The patient is alive with no recurrence or metastasis for eight months after operation. Statistical analysis was made on 136 cases of squamous cell carcinoma of renal pelvis reported in the Japanese literature including our case, and this disease is also briefly reviewed.

[Primary papillary adenocarcinoma of renal pelvis: a case report and review of the literature].

A rare case of primary papillary adenocarcinoma of the renal pelvis is reported. A 75-year-old man was introduced to our institute because of chance hematuria. He had no history of urolithiasis or urinary tract infection. Excretory urography showed a space taking lesion at the lower position of left renal pelvis with low function. Because of advanced stage with paraaortic lymphnode invasion, simple nephrectomy followed by irradiation and systemic chemotherapy with 5-FU was done. He died of pneumonia and acute heart failure after subtotal gastrectomy for peptic ulcer four months after the nephrectomy. Excised specimen revealed papillary adenocarcinoma of the renal pelvis without mucin production. This case was the 51st case reported in the literature. A short review of the disease is also reported.

Exfoliative cytology of a primary adenocarcinoma of the renal pelvis. A case report.

The cytologic features of a primary adenocarcinoma of the renal pelvis in a 64-year-old woman are reported. Cytologic examination of voided urine revealed an ordinary papillary pattern, characterized by clumping of cells with nuclear overlapping, eccentric position of nuclei and cytoplasmic vacuolization due to mucus production. Leukocytes and micro-organisms were also present. Multiple lesions of papillary adenocarcinoma were subsequently found in the right renal pelvis and ureter. The histogenesis of the primary adenocarcinoma seemed to be closely related to columnar-cell metaplasia of lining of the renal pelvis of this patient, who had previously been treated for tuberculosis of the urinary bladder.
