PATHOLOGICAL CHANGES OF TESTICULAR PARENCHYMA IN THE EVENT OF TESTICULAR TORSION AND ITS RESULTS ON FERTILITY
Androgens and bladder outlet obstruction: a correlation with pressure-flow variables in a preliminary study
OBJECTIVES
To determine the relationship between androgens, lower urinary tract
symptoms (LUTS) and urodynamic variables of bladder outlet obstruction
(BOO) in patients with LUTS/benign prostatic hyperplasia (BPH), as
androgens are important in the pathogenesis of LUTS.
PATIENTS AND METHODS
Twenty-five men with symptomatic BPH were enrolled in the study and had
a complete urodynamic investigation, establishing BOO. Age,
prostate-specific antigen level, prostate volume and postvoid residual
volume were recorded and the International Prostate Symptom Score (IPSS)
was estimated. Detrusor pressure at maximum flow (P(det)Q(max)), at
urethral closure (PdetCl, the pressure at the end of urinary flow) and
maximum detrusor pressure (P-detmax) was recorded, while detrusor
overactivity (DO) was noted when present. Blood samples were collected
to measure total testosterone (T), and free T (FT) was calculated.
Patients were grouped according to FT levels as low (< 72 pg/mL) and
normal (FT >= 72 pg/mL).
RESULTS
Ten patients had a low FT level, with a mean (SD) of 54.3 (16.5) pg/mL,
and 15 a normal level of FT, of 90.5 (11) pg/mL. FT was negatively
correlated with PdetCl, and P(det)Q(max); the mean PdetCl and
P(det)Q(max) differed significantly between patients with low and normal
FT levels. Fourteen patients had DO and they had significantly lower
levels of FT than those with no DO. All patients with a FT level of < 60
pg/mL had DO, and the presence of instability differed significantly
from the rest of the group.
CONCLUSIONS
Low T levels in clinical BOO correlated negatively with PdetCl and
P(det)Q(max), while promoting DO. Androgen seems to have an ameliorating
role in lower urinary tract function
Tamsulosin versus transurethral resection of the prostate: Effect on nocturia as a result of benign prostatic hyperplasia
Our objective was to compare the effect of tamsulosin versus
transurethral resection of the prostate (TURP) for the management of
nocturia in previously untreated men with lower urinary tract symptoms
(LUTS) suggestive of benign prostatic hyperplasia (BPH) and no other
predisposing factors for nocturia. The study group included 66 patients
(mean age 68.9 years, range 52-81) randomized to receive either
tamsulosin 0.4 mg per os daily (n = 33) or TURP (n = 33). Nocturia was
assessed at baseline, after 3 months and after 1 year, by the number of
nocturnal awakenings and hours of undisturbed sleep (HUS) obtained from
a 72-h Frequency Volume Chart (FVC). Furthermore, the International
Prostate Symptom Score (IPSS), the International Consultation on
Incontinence Questionnaire Nocturia (ICIQ-N) and the International
Consultation on Incontinence Questionnaire Nocturia Quality of Life
(ICIQ-NQoL) were recorded. At baseline, there were no statistically
significant differences between the two groups. ICIQNQoL and ICIQ-N
scores correlated with the number of awakenings and HUS, respectively.
Both tamsulosin and TURP improved all examined parameters during the
follow up. TURP was associated with a statistically significant
improvement in the number of nocturnal awakenings and in the IPSS,
ICIQ-N and ICIQ-NQol scores in comparison with tamsulosin. HUS increased
in both groups, but without any statistically significant difference. In
conclusion, TURP is superior in comparison with tamsulosin for the
management of BPH-related nocturia
Burned-out testicular tumor with retroperitoneal lymph node metastasis: a case report
Abstract Introduction A burned-out seminoma of the testis is an exceptionally rare clinical entity, with few reports found in the literature. Case presentation A case of burned-out tumor of the testis in a 31-year-old man is reported. The tumor presented as a retroperitoneal mass with histological characteristic of a seminoma. The testes on clinical examination were normal, and a suspicious lesion in the scrotum was only identified after ultrasound. Incision of the abdominal mass was decided, followed by orchectomy. Histological examination of the testis revealed a suspicious lesion with characteristics of spontaneous regression of germ cell tumors. Conclusion We describe one of very few cases worldwide, where spontaneous regression of a primary testicular tumor occurred after demonstration of retroperitoneal lymph node metastasis, a phenomenon known as burned-out seminoma, which is hard to recognize and incompletely characterized by physicians.</p
