Endoscopic management of seminal-vesical cyst with right renal agenesis causing acute urinary retention: Case report.

Seminal-vesicle cysts associated with renal agenesis are rare congenital or acquired lesions. We report a case of seminal-vesicle cyst causing urinary retention in a young patient with right renal agenesis who was treated successfully with transurethral unroofing. Magnetic resonance imaging aided us in making the conclusive diagnosis without the need for any invasive investigations.

A new cause of curvilinear renal calcification: calcified hydrocalycosis.

Although many causes of curvilinear renal calcifications have been described, calcified hydrocalycosis mimicking hydatid cyst has not previously been reported. We report a case of hydrocalycosis which was appeared as a curvilinear calcified cystic lesion resulted from staghorn calculus associated with xanthogranolomatous pyelonephritis (XGPN) on intravenous pyelography (IVU) and computed tomography (CT).

Failure of artificial insemination of husband's semen in the treatment of male infertility.

In the management of infertility, in case semen quality is found insufficient and could not be improved by medical means, handling the available spermatozoa in the most beneficial way has been aimed. Thus, artificial insemination with low quality semen has become a therapeutic alternative. In this study homologous artificial insemination has been used to treat infertility caused by oligoasthenospermia. Eighteen couples have been treated for 58 cycles by intrauterine or paracervical insemination using cervical cups. During the same period 42 cycles with timed vaginal intercourse have been assessed. Though no pregnancies could be obtained following artificial insemination, one pregnancy occurred during no-treatment cycles.

The role of arginine, indomethacin and kallikrein in the treatment of oligoasthenospermia.

We have treated 45 patients with various degrees of oligospermia and asthenospermia with arginine, indomethacin and kallikrein. Fifteen patients have received the amino acid L-arginine hydrochloride, 15 the antiinflammatory agent indomethacin, while 15 others the enzyme kallikrein. These drugs have been administered for at least 3 months to encompass a complete cycle of spermatogenesis. As a result, treatment with these drugs has increased sperm count and motility to some extent. Three pregnancies (20%) have been obtained by arginine and one pregnancy (6.6%) by indomethacin. Though arginine offers some hope for the future, improvement of the fertilizing capacity with these drugs is still controversial.

Urodynamic evaluation in spinal cord injuries.

Spinal cord injury, regardless of its level, causes flaccid paralysis during the shock phase affecting the detrusor and rectal musculature. Then, depending on the level and severity of the lesion, the bladder gains spasticity or remains flaccid. Monitoring the reflex behaviour of detrusor and sphincter activities helps to select the treatment modalities. Thirty patients with cord injuries of various levels have been urodynamically tested at 3-month intervals. The shock phase of the acutely tested patients lasted about 8-9 weeks. Eventually, 23 of the cases were hyperreflexic, while 7 cases remained areflexic: 2 had detrusor-sphincter dyssynergia. The response to treatment has been investigated by cystometrographical and electromyographical methods.
