Papillary adenoma of the prostatic urethra: report of two cases.

Papillary adenoma of the prostatic urethra is a rare cause of hematuria, hemospermia and lower urinary tract obstruction, especially in young adults. We report two cases of papillary adenoma and their endoscopic views. One of the patients had a lesion located on the verumontanum and presented with hematuria, hemospermia and symptoms of lower urinary tract obstruction. The other patient had papillary lesions located in the paramontanal gutter and presented with persistent painless hematuria. The origin of both lesions was proven to be prostatic epithelial differentiation using immunohistochemical identification of prostate-specific antigen. Papillary adenoma is believed to be benign, therefore, both lesions were carefully excised and fulgurated transurethrally.

Simple dorsal plication near the 12 o'clock position for the correction of congenital ventral penile curvature.

Fourteen patients with congenital penile curvature without hypospadias were treated with a modified Essed dorsal plication method between 1998 and 2002 in our clinic. Patient age ranged between 20 and 25 years (mean 22.2). Eight cases (57.1%) had ventral curvature only and six had an additional lateral curvature. There were no significant postoperative complications. One (7.1%) patient had early suture breakage on the 21st postoperative day during erection and underwent re-operation after 9 months. After a mean follow-up period of 23.2 months (range 3-46) all patients were satisfied with the procedure except for one patient (7.1%) who had a residual curvature of 20 degrees. Four cases (28.6%) had minimal shortening of the penis. The overall satisfaction rate with the procedure was 93%. Simple dorsal plication near the 12 o'clock position is a minimally invasive and effective method for the treatment of congenital ventral penile curvature.

Management of ureteral stones with pneumatic lithotripsy: report of 500 patients.

PURPOSE: To evaluate the results of pneumatic lithotripsy (PL) with ureteroscopy in the treatment of ureteral stones. PATIENTS AND METHODS: We reviewed, retrospectively, the records of 500 patients (366 male, 134 female) with ureteral calculi treated by PL with the Swiss Lithoclast. Of these patients, 124 (24.8%) were treated primarily and 376 (75.2%) were treated secondarily after unsuccessful extracorporeal shockwave lithotripsy (SWL). The results were evaluated 3 months after treatment by excretory urography, ultrasonography, or both. RESULTS: The over-all stone-free and fragmentation rates were 94.6% and 96.8%, respectively. These values were 97.1% and 98.5% for stones 10 mm, respectively. The main complications were stone migration (2.0%), urosepsis (3.0%), and ureteral perforation (1.4%). CONCLUSIONS: While SWL is generally excepted as a first-line treatment option in ureteral stones because of its noninvasive nature, in situ lithotripsy, and especially PL, has higher success rates with minimal morbidity. Thus, PL seems to be a good alternative in patients in whom SWL was unsuccessful or not indicated and in patients who need early stone removal.

The importance of re-evaluation in patients with cystitis glandularis associated with pelvic lipomatosis: a case report.

Pelvic lipomatosis is a rare, proliferative disease involving an overgrowth of normal fat in the pelvic retroperitoneal space. Cystitis glandularis, cystitis cystica, or cystitis follicularis can be observed in 75% of patients with pelvic lipomatosis. We describe a 58-yr-old man with pelvic lipomatosis in whom adenocarcinoma of the bladder was diagnosed in the second transurethral resection of the bladder 1 month after the first operation. This proliferative disease can cause obstruction of the bladder drainage leading to a proliferative cystitis because of an altered environment rich in protein fluid. Because the association of this proliferative disease with adenocarcinoma of the bladder is frequent, we recommend close follow-up of these patients to detect the associated adenocarcinoma of the bladder.

Case report: Incidental primary transitional cell carcinoma of the prostate treated with transurethral prostatectomy only.

A 65-year-old man presented with a history of painless gross hematuria and severe obstructive symptoms. Abdominal ultrasonography and intravenous urogram revealed the absence of any disease in the urinary tract except benign prostatic hyperplasia. He underwent a transurethral resection of the prostate and was found to have incidental primary transitional cell carcinoma of the prostatic ducts localized to the gland. Radical cystoprostatectomy was offered but the patient was hypertensive, had a history of cerebrovascular accident and refused another major operation. Since also his general condition was not good enough for further therapy, he was treated with transurethral prostatectomy only. After 16 months he is still alive and free of disease.

The impact of pelvicaliceal anatomical variation between the stone-bearing and normal contralateral kidney on stone formation in adult patients with lower caliceal stones.

OBJECTIVE: We aimed to investigate the effect of pelvicaliceal anatomical differences on the etiology of lower caliceal stones. MATERIALS AND METHODS: Records of adult patients between January 1996 and December 2005 with solitary lower caliceal stone were reviewed. After exclusion of patients with hydronephrosis, major renal anatomic anomalies, non-calcium stones, history of recurrent stone disease and previous renal surgery, 78 patients were enrolled into the study. Lower pole infundibulopelvic angle (IPA), infundibulovertebral angle (IVA), infundibular length (IL), width (IW), number of minor calices and cortical thickness of the lower pole together with other caliceal variables obtained from the whole pelvicaliceal anatomy of both stone-bearing and contralateral normal kidneys were measured from intravenous pyelogram of the patients. Total pelvicaliceal volume was also calculated by a previously described formula for both kidneys. RESULTS: There were statistically significant difference between two kidneys in terms of IW (p < 0.001) and IL (p = 0.002) of the upper calyx, IW (p = 0.001) and IVA (p < 0.001) of the lower calyx), pelvicaliceal volume (p < 0.001), IPA of middle calyx (p = 0.006) and cortical thickness over the lower pole (p < 0.001). However there was no difference between stone-bearing and contralateral normal kidneys in terms of lower pole IPA (p = 0.864) and IL (p = 0.568). CONCLUSION: Pelvicaliceal volume but not lower caliceal properties seem to be a risk factor for stone formation in lower calyx.

Serum interleukin-18 and nitric oxide activity in bladder carcinoma.

BACKGROUND: Both interleukin-18 and nitric oxide are multifunctional molecules that are involved in the different steps of carcinogenesis. METHODS: In the present study, we measured serum interleukin-18 and nitric oxide activity in 51 bladder cancer patients with different tumor stage and grade, and in 8 healthy controls. Serum nitrite-nitrate levels were measured as an index of nitric oxide generation. RESULTS: Serum interleukin-18 levels were significantly higher in bladder cancer patients when compared to the control subjects (p > 0.05). Serum interleukin-18 levels were found to be higher in patients with Ta stage than patients with T1 and T2, T3, T4 stages and in patients with grade 1 tumors than patients with grade 2 and grade 3 tumors, but this was not statistically significant (p > 0.05). There was no significant difference in serum nitrite + nitrate levels between bladder cancer patients and control subjects. CONCLUSIONS: Elevated serum interleukin-18 levels in bladder carcinoma patients may be a result of host defence mechanism against the growth and progression of bladder cancer cells.
