RESUMO

Exstrophy variants are uncommon developmental anomalies of the bladder; the variants involving only the bladder neck are extremely rare. There are only three case reports of inferior vesical fissure (IVF) to date, and usually it's uncommonly associated with other malformations. A combination of inferior vesical fistula (IVF) as an exstrophy variant with urethral atresia and anorectal malformation has not been described previously. We report a case of IVF in a 4-year-old male previously operated for anorectal malformation who was managed with fistula closure with bladder neck reconstruction of lay open of stenosed urethra. Recognition of the exstrophy variant is important because the treatment and prognosis are very different.

RESUMO

In the present study, hexagonal structured borate phosphors BaLaB9 O16 were prepared using a combustion method with colour-tunable emission properties achieved by varying the doping concentration of Eu3+ and Tb3+ in the cluster. The as-prepared materials were analyzed for structural and morphological parameters through X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM) studies. Tuning of colour was predicted through the photoluminescence and photoluminescence excitation spectra of the materials that showed good green and red emissions when doped with Tb3+ and Eu3+ , respectively, whereas the emission of the co-doped sample (Eu3+ and Tb3+ ) can be varied from the green region to red region by varying the excitation range from 207 to 254 nm.

RESUMO

AIMS: There are few studies on the pathology of warty carcinoma (WC) of the penis and these have been from South America. Penile cancers are not uncommon in India. We reviewed the frequency of subtypes of penile squamous carcinoma (SC) and the pathological features and outcome of WC when compared to squamous carcinoma-not otherwise specified (SC-NOS). We also compared the clinicopathological features of WC in our series with those published earlier. MATERIALS AND METHODS: We studied 103 cases of penile cancers over 6 years. Cases were classified into different subtypes according to established histologic criteria. Clinicopathologic features were studied in detail and compared among the different subtypes, especially between WC and SC-NOS. The patients were followed-up and disease free survival in months was noted. RESULTS: SC-NOS constituted 75.7% of all penile cancer cases in our series. The frequency of other subtypes was WC: 9.7%, verrucous: 3.9%, basaloid type and papillary type: 0.97% each, and mixed types 8.7%. The average tumor size and depth of invasion did not differ significantly between the two subtypes. Frequency of lymphovascular emboli and percentage of lymph node metastasis in WC (30 and 10%) were lesser than in SC-NOS (49.37 and 26.58%), respectively. There were no recurrences after partial penectomy in the WC subtype. In the SC-NOS type, three cases had recurrence after partial/total penectomy. CONCLUSION: Warty carcinoma constitutes nearly 10% of all penile squamous cell cancers. These patients seem to have a less aggressive behavior than SC-NOS.

RESUMO

PURPOSE: To predict the outcome of redo-urethroplasty after failed single or multiple open urethral procedures for pelvic fracture urethral distraction defects. METHODS: From January 1997 to December 2006, 43 patients underwent redo-urethroplasty for pelvic fracture urethral distraction defect. Forty-one were referred from other centers. All had undergone open surgery along with an endoscopic procedure (one or more procedures in each patient) which included endoscopic internal urethrotomy, urethral stenting or urethral dilations. RESULTS: There were 43 men with mean age of 29 (range 11-52). Eleven had associated injuries: intraperitoneal bladder rupture (3), bladder neck (2), rectum (3), anal sphincter (2), combined bladder, rectum and anal sphincter (1). Trocar suprapubic cystostomy was performed in 22, rail-road procedures in 10 and open suprapubic cystostomy in 11 along with the management of associated injuries as immediate treatment. Of 43 patients, 28 had progressive perineal, and 12 had transpubic repair. Three patients had total bulbar necrosis, and they underwent prepuceal tube reconstruction (1) and staged substitution with BMG and standard scrotal inlay (2). Analysis of various factors like number of attempts at previous surgery and stricture length did not affect the outcome. A successful result was achieved in 36 (83.72%), improved and stable in five and failure in two. CONCLUSIONS: The overall result of redo-urethroplasty for pelvic fracture urethral distraction defect continues to be gratifying. Failures happen usually within the first 3 months. Substitution urethroplasty can be reserved for those who have long distraction defect. Long-term follow-up is essential using stringent criteria to measure success.

RESUMO

PURPOSE: To identify factors predicting the risk of inguinal metastasis in squamous cell carcinoma of the penis. The therapeutic advantages of early lymphadenectomy in squamous cell carcinoma of the penis must be counterbalanced against its post-operative morbidity. Loss to follow up is a major problem in developing countries. Generating a nomogram based on clinical lymph node status and histopathological findings in the primary tumor could facilitate clinical decision making in the management of penile cancer. METHODS: We prospectively studied 106 patients with penile squamous cell cancer treated from September 2001 to August 2007 at our institution. All patients were offered lymphadenectomy (LAD). A multivariate logistic regression model was used to develop a nomogram. We highlight the problems of loss to follow up in these patients. RESULTS: Of 53 who opted for LAD, 22 had nodal metastasis. The presence of high grade (P = 0.004), lymphovascular invasion (LVI) (P = 0.01) and palpable inguinal lymph nodes (P = 0.05) were the strongest predictors of metastasis. Of 51 who refused LAD, 22 were lost to follow up. Out of these, 16 were at high risk and 9 of them came back with inoperable fungating nodes. A nomogram predicting the risk of lymph node metastasis showed a bias corrected good concordance index (0.74) and good calibration. CONCLUSIONS: High grade and LVI in the tumor along with clinical stage of the inguinal nodes were the strongest predictors of metastasis. These features helped us to develop a nomogram to predict and to identify patients at risk of nodal metastasis.

RESUMO

Association of the anterior and posterior urethral valve is a rare congenital anomaly which can lead to various urinary tract symptoms. An 8-year-old boy was referred by his primary care physician for urinary dribbling, straining at micturition, and recurrent febrile urinary tract infection since the age of 2 years. Clinically, the bladder was palpable; both testes were normal, and, in addition, he had a subcoronal hypospadias. Diagnosis was confirmed by retrograde urethrogram and voiding cystourethrogram (micturating cystourethrogram) and urethroscopy. Cystoscopic ablation of both valves was done by electrocautery hook using low current at 5 o'clock and 7 o'clock directions. He voided with good flow and to completion. Urinary dribbling had completely subsided and renal function was normal at a follow-up period of 36 months with freedom from recurrent urinary tract infection. Both the anterior and posterior urethral valves develop from different embryological sources; thus, this association is rare. A case with this association has not been reported previously in the literature.

RESUMO

PURPOSE: To compare the clinical presentation of prostatic abscess and treatment outcome in two different time frames with regards to etiologies, co-morbid factors and the impact of multidrug resistant organism. MATERIALS AND METHODS: We retrospectively assessed the charts of 48 patients with the diagnosis of prostatic abscess from 1991 to 2005. The period was divided arbitrarily into two different time frames; phase I (1991-1997) and phase II (1998-2005). Factors analyzed included presenting features, predisposing factors, imaging, bacteriological and antibiotic susceptibility profile, treatment and its outcome. RESULTS: The mean patient age in phase I (n = 18) and phase II (n = 30) were 59.22 +/- 11.02 yrs and 49.14 +/- 15.67 respectively (p = 0.013). Diabetes mellitus was most common predisposing factor in both phases. Eleven patients in phase II had no co-morbid factor, of which nine were in the younger age group (22 - 44 years). Of these eleven patients, five presented with pyrexia of unknown origin and had no lower urinary tract symptoms LUTS. Two patients with HIV had tuberculous prostatic abscess along with cryptococcal abscess in one in phase II. Two patients had melioidotic prostatic abscess in phase II. The organisms cultured were predominantly susceptible to first line antibiotics in phase I whereas second or third line in phase II. CONCLUSION: The incidence of prostatic abscess is increasing in younger patients without co-morbid factors. The bacteriological profile remained generally unchanged, but recently multi drug resistant organisms have emerged. A worrying trend of HIV infection with tuberculous prostatic abscess and other rare organism is also emerging.

RESUMO

PURPOSE: We evaluated the effect of the alpha-blocker tamsulosin on stone clearance, analgesic requirements and steinstrasse in shock wave lithotripsy for solitary renal and ureteral calculus. MATERIALS AND METHODS: A prospective, double-blind, randomized placebo controlled study was performed during 1 year involving 60 patients with a solitary renal or ureteral calculus undergoing shock wave lithotripsy. The control group (30) received 0.4 mg tamsulosin and the study group (30) received placebo daily until stone clearance or for a maximum of 30 days. An oral preparation of dextropropoxyphene hydrochloride and acetaminophen was the analgesic used on an on-demand basis. The parameters assessed were stone size, position, clearance time, effect on steinstrasse and analgesic requirement. RESULTS: The overall clearance rate was 96.6% (28 of 29) in the study group and 79.3% (23 of 29) in the control group (p = 0.04). With larger stones 11 to 24 mm the difference in the clearance rate was significant (p = 0.03) but not so with the smaller stones 6 to 10 mm (p = 0.35). The average dose of analgesic used was lower with tamsulosin than with controls, without statistical significance. Steinstrasse resolved spontaneously in the tamsulosin group whereas 25% (2 of 8) required intervention in the placebo group. There was no difference between the 2 groups with regard to age, stone size or location. CONCLUSIONS: The alpha-blocker tamsulosin seemed to facilitate stone clearance, particularly with larger stones during shock wave lithotripsy for renal and ureteral calculus. It also appeared to improve the outcome of steinstrasse. Tamsulosin may have a potential role in routine shock wave lithotripsy.
