Color doppler ultrasonography and spectral analysis of venous flow in diagnosis of varicocele.

OBJECTIVE: The standardization of diagnostic criteria for varicocele has not yet been established. This causes difficulty in evaluating both the incidence and clinical studies. Our aim was to establish diagnostic criteria for varicocele in Doppler procedures. METHODS: The characteristics of blood flow in the internal spermatic vein were investigated with color Doppler ultrasonography (CDU) and venous flow spectral analysis in 100 infertile men without clinical varicocele (group I), 100 infertile men with clinical left varicocele (group II), and 50 fertile men without clinical varicocele served as controls (group III). RESULTS: Three types of flow pattern were found in the spectral analysis of venous flow. If the venous flow was directed to the heart and did not change direction with an intra-abdominal pressure increase, it was classified as type I; venous flow directed to the heart, but changing direction with an intra-abdominal pressure increase, was classified as type II, and blood flow directed to the testicles and augmenting with an intra-abdominal pressure increase, was classified as type III. In group I, flow patterns were 39, 56 and 5% on the left side and 55, 42 and 3% on the right side for types I, II and III, respectively. In group II, flow patterns were 0, 35 and 65% on the left side and 61, 38 and 1% on the right side for type I, II and III patterns, respectively. In group III, the figures were 44, 54 and 2% for the left and 54, 46 and 0% for the right. Type II and III flow patterns were seen more frequently than type I in patients with clinical left varicocele (p<0.001). Whereas type I and II flow patterns were more common than type III in subjects without clinical varicocele (p<0.05). A type II flow pattern during normal breathing was seen at a lower rate in the control group than in the other groups (p<0.05). CONCLUSION: Spectral analysis of Doppler waves should be used in combination with CDU for the diagnosis of varicocele. Varicocele should not only be diagnosed with a type II flow pattern which occurs during valsalva. For the diagnosis of varicocele, the main criterion must be a type III pattern flow, as well as a type II pattern during normal breathing.

Serum PSA and age-specific reference ranges in patients with prostatism symptoms.

Prostatic specific antigen (PSA), a tumour marker helpful in the diagnosis and follow-up of prostate cancer, may rise due to causes other than prostate cancer (i.e. BPH, acute prostatitis, etc.). Investigations in order to increase the sensitivity and specificity of PSA in prostate carcinoma are being carried out. Serum PSA levels of patients with prostatism with regard to age as well as these levels in the male population at risk but without clinical prostatic disease (those above the age of 40) should be well documented. The aim of this study is to find age-specific values and ranges of PSA in patients with prostatism symptoms.

Echo-colour doppler ultrasonography in the diagnosis of varicocele.

The relationship between varicocele and infertility has long been defined. About a third of the male patients undergoing evaluation for infertility present with a varicocele. Sixty male patients between 17 and 35 years of age (mean 25.6) were examined with a colour-doppler flow imaging system. The diameters of the veins in the pampiniform plexus were measured by gray-scale sonography. Our findings were classified with regard to venous diameter, the existence or non-existence of reflux, the circumstances under which these findings were recorded (e.g. during normal respiration and standing position or during Valsalva manoeuvre and supine position). Finally our results suggest that: (a) the clinical significance of the presence of dilated veins or reflux during increased intraabdominal pressure and under similar circumstances should be regarded with caution; (b) positive findings during normal inspirium are highly significant (grades III and IV).

Fracture of the penis.

Fracture of the penis is a rare condition. The fracture is easy to recognize but treatment remains controversial. Between December 1991 and January 1997, eleven patients underwent emergency operation on the first day after penile fracture. Our operative plan consisted of immediate exploration, identification, debridement and primary repair of the tear in the tunica albuginea. The patients' mean age was 27 years (range 21-38 yrs.). Penile fracture was due to sexual manoeuvres in 8, manipulation in 2 and fall onto erect penis in one of 11 patients. The mean hospitalization time was 2.2 days (range 1 to 3 days). There was no significant early postoperative complication except wound infection in one patient. In the first postoperative month, there was a residual fibrosis due to nonabsorbable sutures in one patient and mild pain during coitus in the other one. All patients had full erection and no patient needed additional treatment. To avoid serious complications and preserve penile functions immediate surgical intervention is recommended.
