Urethral reconstruction after total penectomy for urethral cancer.

A 59-year-old white man developed a ventral ulcer with irregular limits in the middle portion of the penis. The result of the pathologic analysis was compatible with invasive squamous cell urethral carcinoma. A total penectomy was performed. In these cases, the usually recommended urinary diversion is perineal urethrostomy. However, due to the specifications of the case, perineal urethrostomy could not be performed. The literature did not offer any other alternative for patients with this same condition. Therefore, a urethral reconstruction using a groin skin flap had to be performed.

Malacoplakia or prostate cancer? Similarities and differences.

Malacoplakia is a granulomatous inflammatory disorder clinically and ultrasonographically very similar to prostatic adenocarcinoma. Symptoms and physical findings are similar to prostatism and in half of the patients the differential diagnosis includes malignancy, mainly because of the presence of a hard nodule on digital rectal examination. Additionally, cases of malacoplakia can show hypoechoic nodes on transrectal ultrasound mimicking adenocarcinoma. We report a case of malacoplakia of the prostate with emphasis on its similarities and differences with prostate adenocarcinoma.

[Treatment of hemangioma of the glans penis using Nd:Yag laser. Apropos of a case]. / Traitement de l'hémangiome du gland par laser Nd:Yag. A propos d'un cas.

Hemangioma of urinary tract are unusual, being about 2% of all hemangiomas. We present a case of a glans penis hemangioma. There is controversy concerning their treatment and outcome. Our patient was treated with a Neodymium: Yag laser irradiation, with complete morphological recuperation.

[Urinary flow in children: correlation with age, body height and body surface area]. / Débitmétrie dans l'enfance: corrélation avec l'âge, la taille et la surface corporelle.

Peak flow rate data (Qmax) are important for diagnosis of lower urinary tract obstruction. However, the lack of uroflowmetry studies in children, makes their interpretation difficult. With this aim, we studied 167 boys classified in four groups according to their age (G1: n = 48, 6-7 years; G2: n = 43, 8-9 years; G3: n = 37, 10-11 years; G4: n = 39, 12-14 years). We studied in all children, weight, height, body surface area, peak flow rate (Qmax) and the correspondant urinary volume (Vol). Means and standard deviations of Qmax (ml/sec) were: 15 +/- 5 (G1), 15 +/- 5 (G2), 17 +/- 5 (G3) and 22 +/- 7 (G4) respectively. Corresponding urinary volumes (Vol) (mean standard deviation-in ml) were: G1 = 123 +/- 75; G2 = 122 +/- 79; G3 = 158 +/- 96 and G4 = 162 +/- 101. We found a significant correlation (p < 0,01) between Qmax and Vol in groups G2, G3 and G4; and between Qmax and height in groups G1 and G4. The authors demonstrated a positive correlation between maximum flow and voided volume, and an increase of Qmax with age.
