    Objective This study was carried out to evaluate the urodynamic characteristics of the Camey II, Kock's and W-configured ileal reservoirs utilized for orthotopic urinary diversion. Patients and Methods Between January 2000 and 2002, 42 male patients prospectively underwent radical cystoprostatectomy for bladder cancer followed by orthotopic urinary diversion at the urology department of Cairo University hospitals. All cases were evaluated clinically, bacteriologically, radiologically and urodynamically including uroflowmetry, medium-fill and voiding enterocystometry and urethral pressure profilometry, which was done in the early and late postoperative period (at 3-6 months and 6-18 months). Patients were divided into four groups: Group I: 11 cases with preservation of the prostatic apex and creation of a W-neobladder. Group II: 11 cases without prostatic apex preservation and creation of a W-shaped ileal pouch. Group III: 12 cases without prostatic apex preservation and creation of a Camey II pouch. Group IV: 8 cases without prostatic apex preservation and creation of a Kock's pouch. Results The patients of Group I had a larger mean neobladder capacity (699 ml) and volume at which the first contraction occurred (315 ml) and a larger amount of residual urine (224 ml) as compared to Group II (511.1, 285 and 77.5 ml, respectively), Group III (375, 200 and 55 ml, respectively) and Group IV (563, 266 and 600 ml, respectively). Also Group I with a preserved prostatic apex had a higher mean intraluminal opening pressure (55 cm H2O) and a higher pressure at maximum flow (62.36 cm H20) as compared to the patients with complete prostatic resection. Conclusion We conclude that the patients with a preserved prostatic apex (Group I) had a statistically significant higher mean residual urine in the early and late postoperative period and a significantly higher mean maximum cystometric capacity in the late postoperative period as compared to those recorded in patients with complete prostatic resection (Groups II, III, IV). A higher incidence of upper tract deterioration was detected in Group I (35%) vs. 4.6%, 27.8% and 12.5% in Groups II, III and IV, respectively.

Matériel et Méthodes De Janvier 2000 a 2002, 42 patients de sexe masculin ont bénéficié d'une cysto-prostatectomie radicale pour cancer de la vessie suivie d'une dérivation urinaire orthotopique au Département d'Urologie des HÎpitaux Universitaires du Caire. Tous les cas ont été évalués aux plans cliniques, bactériologiques, radiologiques et urodynamiques incluant une débit-métrie, entérocystométrie de milieu de remplissage et mictionnelle et une profilométrie qui a été realisée en post-opératoire immédiate et tardif (à 3-6 mois et à 6-18 mois). Les patients étaient divisés en 4 groupes : Groupe I : 11 cas avec préservation de l'apex prostatic et création d'un réservoir en W. Groupe II : 11 cas sans préservation de l'apex et création d'une poche iléale en W. Groupe III : 12 cas sans préservation de l'apex prostatique et création d'une poche de type Camey II. Groupe IV : 8 cas sans préservation de l'apex et création d'une Poche de Kock. Résultats Les patients du Groupe I ont eu une plus grande capacité néo-vésicale moyenne (699 ml), un premier besoin plus tardif (315 ml) et un résidu post-mictionnel plus important (224 ml) comparé au Groupe II (511.1, 285 et 77.5 ml, respectivement), au Groupe III (375, 200 et 55 ml, respectivement) et au Groupe IV (563, 266 et 600 ml, respectivement). Aussi les patients du Groupe I avec préservation de l'apex prostatique ont une pression de clÎture moyenne plus élevée (55 cm H2O) et une plus grande pression urinaire maximale (62,36 cm H20) comparé aux patients avec ablation complÚte de la prostate dans les Groupes II, III et IV, qui ont respectivement une pression de clÎture de 32,67 et 35,3 cm H2O. Conclusion Nous concluons que les patients avec préservation de l'apex prostatique (Groupe I) ont, de façon statistiquement significative, un résidu post-mictionnel moyen plus élevé aussi bien en post-opératoire immédiat que tardif et une capacité néo-vésicale moyenne plus élevée en post opératoire tardif comparés aux patients avec ablation complÚte de la prostate (Groupes II, III et IV). Une plus grande fréquence de détérioration du haut appareil urinaire a été détectée dans le Groupe I (35 %) versus 4,6%, 27,8% and 12,5% respectivement dans les Groupes II, III et IV.

    Introduction and objectives: Despite being uncommon, infantile kidney stone remains a major health problem due to its higher recurrence rate and morbidity. The parents usually notice that their infants have recurrent fever and failure to thrive of unknown origin. Those patients comprise a big challenge for the urologist in management. Therefore, this study aimed to evaluate the outcome of shockwave lithotripsy (SWL) in management of renal stones in infants. Subjects and methods: A retrospective analysis of prospectively collected data performed between January 2009 and December 2012 for infants underwent SWL for single radio-opaque renal stones ≀15 mm at a single stone center. SWL was performed with Dorneir S lithotripter with a maximum of 1500 shocks per session. A single session was indicated for each infant, but a second session was performed when satisfactory disintegration was not achieved. Follow-up based on urinalysis, urine culture and sensitivity, plain X-ray kidney ureter bladder (KUB) and abdominal ultrasonography (US) was carried out 2 weeks post SWL and monthly for 3 successive months. Multislice Computed tomography (MSCT) was performed 3-months post-SWL to confirm the stone-free status. Results: A total of 87 infants, less than 24 months of age were enrolled in this research. SWL success was defined as absence of any residual fragments on MSCT 3-months after the last session. Stone free rate was 93.1% after the first SWL session and reached 100% after the second session. Rate of retreatment with second session of SWL was 6.9%. Urinary tract infection (UTI) was detected in 10.3%, transient renal obstruction with low grade fever in 4.6% of infants and no major complication had been recorded. Conclusion: The new generation of SWL technology with a precise focal area seems to be safe and effective in management of kidney calculi in infants
