The role of extracorporeal shockwave lithotripsy in an asymptomatic special patient group with small renal calculi.

BACKGROUND AND PURPOSE: Data concerning extracorporeal shock wave lithotripsy (SWL) management of small (< or = 5 mm) asymptomatic renal caliceal stones are lacking in the literature. In this study, we aimed to determine the effectiveness of SWL in a special group of patients who had very small (< or = 5 mm) asymptomatic renal caliceal stones. The group of patients consisted of pilots, gendarmes, and soldiers, such as commandos, for whom treatment was obligatory and who had to be stone free because of their military duties. PATIENTS AND METHODS: We retrospectively examined SWL data and retrieved information for 84 patients with small asymptomatic renal caliceal stones. The SWL sessions were performed with a Siemens Lithostar lithotriptor. The mean age of the patients was 34 +/- 13 years. The mean stone size was 4.8 +/- 0.4 mm. The mean numbers of shockwaves and energy used were 2707 +/- 1742 and 18 +/- 2 kV, respectively. The location of stones were: 11 right upper calix, 10 right middle calix, 17 right lower calix, 13 left upper calix, 16 left middle calyx, and 17 left lower calix. Eighty-four patients underwent 101 SWL sessions. Only eight patients had second and three patients had third SWL treatments. SWL was performed five times for only one patient. All mean values were realized with an SPSS 10.0 statistical program. RESULTS: After the first, second, and third SWL sessions, the stone-free rate was calculated as 87%, 93% and 94%, respectively. Only five patients with lower renal caliceal stones were not stone free. The reported complications were macroscopic hematuria necessitating medical attention in four patients, skin ecchymosis in seven patients, severe colic pain in two patients, and urinary-tract infection in one patient. There was no need for hospitalization for these complications. CONCLUSION: SWL is effective and safe in patients with very small (< or = 5 mm) asymptomatic renal caliceal stones in all locations.

Renal papillae metastasis of sigmoid colon adenocarcinoma.

Colonic carcinoma metastatic to the kidney is very rare. The usual anatomical localization for secondary renal neoplasms is the renal cortex. We report a case of sigmoid colon carcinoma with unilateral kidney metastasis localized only in the renal papillae without obvious metastatic disease.

Penile prosthesis extrusion due to gonococcal infection.

Gonococcal infection of a penile prosthesis is a rare presentation of a common disease. Here we report two cases of penile prosthesis extrusion due to gonococcal infection.

Nephrogenic adenoma of the bladder in a girl with Turner's syndrome: an unusual association.

We describe a nephrogenic adenoma of the bladder in a 14-year-old girl with Turner's syndrome. The patient also had a past history of urological surgery for vesicoureteral reflux. In this case, the multifocal lesions were successfully treated by transurethral resection.

Fibroepithelial polyp originating from the glans penis in a child.

A fibroepithelial polyp is a benign neoplasm that occurs throughout the urinary tract. In this article, we report a pediatric case of a fibroepithelial polyp originating from the glans penis. To our knowledge, this is a previously unreported lesion arising from the glans penis.

Accessory scrotum attached to a perineal lipoma in an adult male.

Accessory scrotum is a condition in which a scrotum is located in the perineal region, in addition to the presence of normally located primary scrotum, testes and penis. The condition is extremely rare and the majority of reported cases have been diagnosed in infants. Herein, we present a case of accessory scrotum attached to a perineal lipoma in a 40-year-old man. The perineal mass was present at birth and grew very slowly over the years. There were no other congenital abnormalities or problems related to this anomaly. The case was easily managed by complete excision of the accessory scrotum and perineal lipoma. Gross and microscopic examination of the surgical specimen revealed an accessory scrotum attached to an encapsulated perineal lipoma. The present case demonstrates an adult prognosis of a patient born with this type of abnormality. To our knowledge, it is the first case of its kind to be reported in the literature.

Priapism in a patient receiving long-term chlorpromazine therapy. A case report.

Priapism is an uncommon urologic emergency with a variety of known etiologies including the use of psychotropic medications. We report a priapism case who has taken chlorpromazine for 3 years.

Retrospective analysis of 74 cases of seminoma treated with radiotherapy.

BACKGROUND: Standard post-orchiectomy radiotherapy (RT) is accepted as a standard management option for stage I seminoma. METHODS: Retrospective evaluation of 74 patients with stage I seminoma was performed according to the Royal Marsden staging system. All of the patients underwent RT in the Radiation Oncology Department of Gülhane Military Medical Academy between 1974 and 1995. The median age of patients was 27 years (range, 20-56). Radiotherapy was applied to all of the patients after orchiectomy for adjuvant purposes. Sixty-nine patients underwent RT while five patients who had recurrence received chemotherapy following radiotherapy. RESULTS: After a mean follow-up period of 54 months, the 5-year overall survival rate was 98.61%, which complied with the literature. The disease-free survival rate was 90.54%. According to the World Health Organization toxicity scale, acute enteritis was 9.4% for grade I and 5.4% for grade II, while nausea/vomiting was 36.4% for grade I and 5.4% for grade II. CONCLUSION: To avoid acute toxicity related to RT, prognostic risk factors should be well-known and patients with low risk factors should be monitored carefully after orchiectomy. RT should be directed to the para-aortic +/- ipsilateral pelvic lymph nodes in high risk patients. Although post-orchiectomy RT is a traditional management option for clinical stage I seminoma, the results of RT should be well-known to compare it with other treatment options (e.g. RPLND, adjuvant chemotherapy and surveillance).

Intraurethral prostatic cyst: a rare cause of infravesical obstruction.

A case is reported here of symptomatic intraurethral anterior midline prostatic cyst in a 52-year-old man whom transurethral resection of the cyst was performed successfully establishing the resolution of voiding symptoms.

Extracorporeal shock wave lithotripsy treatment in paraplegic patients with bladder stones.

BACKGROUND: Spinal cord injury patients are at increased risk of developing urolithiasis and many will require treatment, most commonly with extracorporeal shock wave lithotripsy (ESWL). METHODS: We examined 20 consecutive spinal cord injury patients (all male) undergoing ESWL for the treatment of bladder stones between April 1992 and May 2000. The mean number of shock waves administered in these 20 patients was 3600 and the shock power was 19 kW/s. All patients were treated without anesthesia. After ESWL, the bladder was irrigated with povidone iodine solution and stone fragments were evacuated through a 22F endoscopic sheath. RESULTS: All patients became stone-free after ESWL. Stone fragments were observed in the urethra of 3 patients, which were removed by urethroscopy. No major complication was observed; however, 5 patients had minor hematuria (which subsided within 24 h) and subfebrile fever (37.2-37.5 degrees C). CONCLUSION: ESWL and transurethral bladder irrigation is a safe, effective and simple modality for the treatment of bladder stones in spinal cord injury patients.
