[Angioleiomyoma of the ureter]
SO - Urologiia 2001 May-Jun;(3):43-5
Angioleiomyoma of the urinary excretory tract is an unusual, but benign
condition. A case of pure angioleiomyoma of the ureter is reported.
Renal tract ultrasonography showed hydronephrosis on the right side in a
15-year-old boy without urinary symptoms. Subsequent retrograde biopsy
suggested leiomyoma. Nephrureterectomy was performed. Histologically,
the removed specimen indicated ureteral angioleiomyoma. Difficulties in
diagnosis and surgical treatment are discussed.

Nephrourete-rectomy with excision of a bladder cuff has been the
standard treatment of the upper urinary tract transitional cell
carcinoma. The very indolent behavior (GI, II, Ta, T1) of more than 50%
and up to 82% of the upper urinary tract tumors treated with
nephroureterectomy in different series in conjunction with the advent of
sophisticated endourological techniques have permitted in certain cases
alternative treatments using a conservative approach with either
ureteropyeloscopy or percutaneous access. Ureteroscopy is reserved for
ureteral tumors and small, simple tumors of the renal pelvis (< 1.5 cm)
while large or multiple tumors of the renal pelvis are approached in a
percutaneous way. During 14 years 64 patients with transitional cell
carcinoma of the upper urinary tract were treated percutaneously at our
department at Long Island Jewish Medical Center, 15 (23.5%) with grade
I, 26 (40.6%) with grade II and 23 (35.9%) with grade III and IV. After
a mean follow-up of 51 months, percutaneously treated patients had a
tumor specific survival of 85.6%, being 100% for GI tumors, 96.1% for
GII and 60.8% for GIII. Recurrence of grade I tumors were observed in
20%, 26.9% for grade II and 56.5% for Grade III. In conclusion, with a
rigorous follow-up transitional cell carcinoma of the upper tract with
low and moderate grades (GI, GII, Ta, T1) can be treated endorologically
even in the presence of a normal contralateral kidney with low morbility
and a long term efficiency comparable to a nephroureterectomy. An
elective endorologic management for GIII tumors is not recommended.
Endoscopic conservative surgery can be offered when the criteria of good
prognosis are found for Ta (such as absence of carcinoma in situ,
presence of diploidy, low p53 expression and a single tumor) and in the
cases of a solitary kidney or chronic renal insufficiency or for poor
surgical candidates for T1. Patients with stage T2-T3 should be offered
a nephroureterectomy.

The BTA stat test: a tumor marker for the detection of upper tract
transitional cell carcinoma.
SO - Urology 2001 Oct;58(4):532-5
AD - Department of Urology, Belfast City Hospital, Belfast, Northern Ireland,
UK.
OBJECTIVES: To conduct a prospective evaluation to determine the utility
of the BTA stat test in the detection of upper tract transitional cell
carcinoma (UTTCC). Monitoring for UTTCC currently relies on invasive
procedures such as upper tract imaging, ureteral washing cytology (UWC)
and/or ureteroscopy, or voided urine cytology (VUC). The BTA stat test
is a sensitive qualitative immunoassay that detects human complement
factor H-related protein in voided urine. METHODS: A total of 81
patients participated, 27 with histopathologically confirmed UTTCC, 26
with upper tract calculi, and 28 with microscopic hematuria but no
evidence of urologic disease. Voided specimens collected before surgery
or treatment were tested with the BTA stat test and VUC. UWC was
performed in specimens collected by a ureteral catheter. RESULTS: The
BTA stat test was significantly more sensitive and specific than VUC or
UWC. The overall sensitivity for each was 82%, 11%, and 48%; the
specificity was 89%, 54%, and 33%. The positive predictive value for the
BTA stat test was 79% and the negative predictive value was 91%, both
the highest of the three tests. CONCLUSIONS: The BTA stat test was
superior to VUC and UWC in the detection of UTTCC. These results may
support the adoption of a less aggressive follow-up policy when
monitoring for UTTCC when the BTA stat result is negative. If cystoscopy
is negative and the BTA stat test is positive, upper tract
investigations should be expedited and, if the bladder is in place,
bladder biopsies performed.

Kidney morcellation in laparoscopic nephrectomy for tumor:
recommendations for specimen sampling and pathologic tumor staging.
SO - Am J Surg Pathol 2001 Sep;25(9):1158-66
AD - Department of Pathology, University of California, San Francisco 94143,
USA. josra@itsa.ucsf.edu
Laparoscopic nephrectomy is a novel approach for small renal tumors in
selected patients; however, removal of the kidney through the small
laparoscopic abdominal wall incision site requires the kidney to be
morcellated into small fragments while still in situ. Morcellation
presents two problems for the pathologist. First, guidelines for optimal
sampling of morcellated fragments have not been described. Second,
morcellation precludes complete pTNM tumor staging, in particular, tumor
size, margins, and renal vein involvement. Based on our initial
experience with 23 laparoscopic nephrectomies/nephroureterectomies (13
clinically suspected neoplasms, confirmed pathologically as renal cell
carcinoma [RCC, n = 7], urothelial carcinoma of the renal pelvis [n =
3], angiomyolipoma [n = 1], and cystic nephroma [n = 1], and 10
clinically benign entities) and a conservative statistical model, we
present a decision analysis model of various specimen sampling protocols
that optimize cost, labor, or time to diagnosis (single vs sequential
sampling). Using the tumor-to-kidney volume ratio (TKR), calculated from
preoperative radiologic imaging and specimen gross weight, several
specimen sampling algorithms were compared. For the average situation in
which TKR is > or =0.15, the algorithm that most significantly optimizes
cost and labor is one that initially samples 5% of the morcellated
specimen. However, additional sampling may be required in one fourth of
the cases. The optimal amount of sampled tissue may indeed be less than
5% because this assumes no suspicious tissue is grossly visible and in
all our cases of RCC grossly visible tumor was identified. Additional
nomograms for a spectrum of TKR, sampling success, and cost are
presented to allow pathologists their own discretion in determining
optimal sampling of the morcellated kidney. Tumor staging is severely
limited by morcellation. Tumor size, renal capsule involvement, and
renal vein involvement cannot be fully pathologically evaluated for RCC,
whereas invasion cannot be definitively assessed for urothelial
carcinoma of the renal pelvis. Knowledge of the radiologic features
(lesion size, capsule, and vein involvement) is important in sampling
and staging morcellated kidneys removed laparoscopically.

Cross-sectional imaging in ureter tumors: findings and staging accuracy
of various modalities.

AD - Department of Radiology, School of Medicine, Ankara University, Ibn-i
Sina Hospital, 06100, Sihhiye-, Ankara, Turkey. cetinatasoy@hotmail.com
We present cross-sectional imaging findings in eight patients with
ureter tumors. Eight patients were examined by computed tomography (CT),
seven by ultrasonography (US), and five by magnetic resonance imaging
(MRI). All the lesions were detected by the three modalities. All
modalities were accurate in excluding the periureteral invasion and
lymphadenopathy in Stages 1 and 2 tumors. While CT and MRI identified
the periureteral invasion and lymphadenopathy in four patients with
advanced tumors, US failed to show the local invasion in three of four
patients. Nevertheless, enlarged retroperitoneal lymph nodes could be
detected sonographically in the three Stage 4 tumors. CT and MRI appear
to have a high diagnostic sensitivity and staging accuracy in ureter
tumors. Although US detects ureter tumors efficiently, this technique
seems to be unreliable in showing local invasion in a substantial number
of patients.

Center, Durham, North Carolina 27710, USA. michael.zenn@duke.edu
BACKGROUND: Introital stenosis from both bony and soft tissue
contracture is an unusual clinical problem not well addressed in the
literature. CASE: A woman with a history of pelvic irradiation at age 1
for malignancy presented with severe introital stenosis unresponsive to
conservative topical and dilatational therapy. She ultimately required
staged bony resection of her infantile pelvis and soft tissue
reconstruction to reestablish her introital aperture to an adequate and
functional size. CONCLUSION: Introital stenosis from childhood requires
a different treatment because development of the pelvis may not have
been normal, and bony narrowing may exist in conjunction with soft
tissue contracture. A staged multispecialty approach is recommended to
treat this interesting variant of introital stenosis.

Urothelial malignant disease and Chinese herbal nephropathy.

We have previously reported occurrence of a specific type of nephropathy
due to ingestion of Chinese herbs (Chinese herbal nephropathy [CHN]) in
two patients in the UK. These cases highlighted the role of aristolochic
acid in causing this nephropathy, which was first described in a Belgian
cohort. We now report development of invasive transitional cell
carcinoma of the urinary tract associated with the presence of
aristolochic acid-DNA adducts in one of these patients. This work
clearly shows the carcinogenic potential of aristolochic acid in this
new type of nephropathy.

Expression of telomerase catalytic subunit (hTERT) mRNA does not predict
survival in patients with transitional cell carcinoma of the upper
urinary tract.

Telomerase is a ribonucleoprotein enzyme that synthesizes telomeric
repeats onto chromosomal ends using a segment of its RNA component as a
template. Its activity has become an established indicator of the
diagnosis, biological behavior, and prognosis of several tumors.
However, few studies have investigated the diagnostic and prognostic
importance of the expression of telomerase catalytic subunit (hTERT)
mRNA in transitional cell carcinoma of the upper urinary tract
(TCC-UUT). We investigated the expression of hTERT mRNA using in situ
hybridization in 125 cases of TCC-UUT, and also its relation with the
expression of telomerase RNA component (hTERC), proliferating cell
nuclear antigen (PCNA) immunoreactivity, clinicopathologic parameters,
and clinical outcome. A positive expression of hTERT mRNA was recognized
in 93.6% of the samples and was apparent within the cytoplasm of tumor
cells. In the normal urothelium examined in a few cases, its expression
was barely detected. hTERT mRNA scores showed a significant association
with hTERC score. However, no relationship was found between the
expression of hTERT mRNA and clinicopathologic findings, PCNA index, or
prognosis. These results suggest that the expression of hTERT mRNA does
not predict prognosis in TCC-UUT.

The endoscopic approach to the distal ureter in nephroureterectomy for
upper urinary tract tumor.
SO - J Urol 2001 Dec;166(6):2017-22
AD - Department of Urology, University Medical Center St. Radboud, Nijmegen,
The Netherlands.
PURPOSE: We reviewed the current status of the endoscopic distal
ureteral approach to nephroureterectomy for transitional upper urinary
tract cancer. MATERIAL AND METHODS: We reviewed the English, French and
Spanish literature using a PubMed and MEDLINE search, and compared the
stripping and pluck techniques. Statistical analysis was done using
Fisher's exact test. Individual case reports are discussed but they were
not included in the statistical analysis. RESULTS: The mean rate of
bladder carcinoma recurrence after ureteral resection and detachment is
19.3% for the stripping and 24% for the pluck technique. This difference
is not statistically significant. In 3.1% of cases invasive bladder
cancer has been noted but only after distal ureteral resection using the
pluck technique. CONCLUSIONS: The endoscopic approach to the distal
ureter during nephroureterectomy is feasible. Bladder cancer recurrence
was similar after each technique. However, isolated case reports
illustrate the need for cautious selection of surgical candidates.

upper pole of the left kidney and atrophic right kidney. Systemic
chemotherapy with CDDP, MTX and ADR was performed preoperatively. Then,
hemi-left nephrectomy underwent with the diagnosis of renal pelvic tumor

A cytogenetically detectable form of gene amplification, presumably
oncogene amplification, double minute chromosomes, has been found in 11
out of 45 specimens (24%) of moderately and poorly differentiated,
deeply infiltrating transitional cell carcinoma of the bladder and
ureter. None of the 75 low-grade low-stage tumors contained this
karyotypic anomaly. It is obvious that double minutes are not a rare and
sporadic phenomenon in this type of tumors; additionally there is strong
evidence that they are involved in tumor progression, i.e. they are
associated with tumor aggressiveness and unfavorable prognosis.

We used comparative genomic hybridization to analyze 10 primary tumor
samples from patients with transitional cell carcinoma of the renal
pelvis. The most frequent loss was located at 9q, that is, in 50% of the
tumors. Gains of DNA sequences were most frequently observed in
chromosome regions 1q21 approximately q23, 2p23 approximately p25,
8q21.1 approximately q22 and in the whole chromosome 20. High level
amplifications at 1q21 approximately q25, 6p22 approximately p23, 8q21
approximately q22, 8q22 approximately q24.1, 11q13, and 12q14
approximately q21 were detected. Most of these regions have previously
been reported to be involved in transitional cell carcinoma of the
bladder, thus confirming the importance of an increasing number of
chromosome imbalances in the development and progression of this type of
tumors.

Transitional cell carcinoma of the renal pelvis is relatively uncommon,
and only 5% of all urothelial carcinomas occur in the renal collecting
system. Invasive tumors are often aggressive in their biological
behavior and show a high tendency for systemic progression. Conservative
therapy should only be considered an option in patients with imperative
indications (solitary functioning kidney, bilateral tumor, renal
insufficiency). In some cases, organ-sparing techniques such as open
resection or endourological treatment (percutaneous or by ureteroscopy)
can be performed. However, nephroureterectomy with excision of a bladder
cuff is considered to be the standard treatment and should be performed
whenever possible.

Nephroureterectomy is the standard treatment of tumors in the upper and
middle third of the ureter. Whereas, resection of the distal ureter and
uretercystoneostomy is the treatment of choice of tumors in the lower
third, as long as there is enough renal function which is worthwhile to
be preserved. Lymphadenectomy should be performed in all patients
suspicious for invasion of the ureteral wall since already 10% of
patients with pT1 and pT2 tumors will present with metastases to the
lymphnodes. In case of functional or anatomic single kidney therapy has
to be adapted to the patient and tumor appropriately. Endoscopic
resection, partial or complete resection of the ureter with substitution
by ileum or autotransplantation with pyelovesicostomy are the operative
options. Elective endoscopic treatment of ureteral tumors should be done
in patients with G1 tumors only. However, the recurrence rate is as high
as 30 to 60% and the mean interval to recurrence is about 9 months.
Regular followup by means of cytology and endoscopy is mandatory.
Laparoscopic nephroureterectomy is still a experimental treatment at
present time and should be not considered in the treatment of ureteral
tumors because of the complexity of the procedure and the risk of tumor
spillage.

pedunculated polyp) is a rare benign epithelial tumour, more frequently
encountered in males and in the posterior urethra. When it appears in
females it is usually located in the external meatus and normally
asymptomatic, although it can also present with a mictional syndrome,
terminal hematuria or urethral hemorrhage. The differential diagnosis
includes other benign epithelial tumours of the urethra, such as the
caruncula, mainly the granulomatous, very difficult to differentiate,
the squamous papilloma and the acuminated chondiloma. A clinical
examination and histological study are necessary for a correct
diagnosis, and treatment consists of surgical resection.

We report a new case of simultaneous occurrence of renal cell carcinoma
and transitional cell carcinoma into ipsilateral ureter. A review of the
literature to date indicates this is the 45 world-wide case and the 8 in
the Spanish publications.
