Incidental renal cell carcinoma-age and stage characterization and clinical implications : Study of 1092 patients (1982-1997)

OBJECTIVES To compare the epidemiologic, clinical, and pathologic characteristics of incidental and symptomatic renal cell carcinoma in a large series of patients, with emphasis on age distribution and its potential impact in defining groups of patients that may benefit from early detection programs. METHODS Records of 1092 patients with renal tumors from 1982 to 1997 were reviewed. Age, clinical presentation, and pathologic stage and grade were analyzed. Special attention was given to the age distribution and its relationship to the incidental or symptomatic diagnosis. RESULTS The overall mean age and proportion of patients older than 65 gradually increased (from 57 to 62.6 years and from 24.7% to 48.7%, respectively) from 1982 to 1997. The mean age in the incidental group rose steadily higher than in the symptomatic group. A progressive increase of incidental tumors from 13.0% in 1982 to 1983 to 59.2% in 1996 to 1997 was observed. A lower stage (74.3% versus 49.1%), grade (75.5% versus 56.9%), and percentage of metastases at presentation (10.4% versus 19.6%) were registered in the incidentally found neoplasms than in the symptomatic neoplasms. Eighty-two (80.4%) of 102 patients who underwent conservative surgery had incidental renal cell carcinoma. CONCLUSIONS Our data confirm a rapid and dramatic change in the epidemiologic and clinical characteristics of renal cancer, with an increasing number of incidentally found tumors presenting with lower stage, grade, and percentage of metastases. An unexpected but significantly higher rate of renal neoplasms was observed in older patients. The stage, grade, and patient age observed in our series of incidentally found tumors raises the question of whether to leave the current diagnostic approach unaltered, thus benefiting a subgroup of patients with clinically unrecognized and possibly indolent renal cell carcinoma, or to extend early detection programs to younger patients with potentially more aggressive tumors.

The Pathophysiology, Diagnosis and Therapy of the Transurethral Resection of the Prostate Syndrome

In this article, the authors analyze a syndrome first described by Creevy in the 1940s, which may occur during a transurethral resection of the prostate (TURP). The syndrome is characterized by cardiocirculatory and neurological problems due to rapid changes in intravascular volume and plasma solute concentrations caused by excess irrigating fluid absorption. This article reviews the available literature and reports on the experience of our clinic, a specialist department in the physiopathology, diagnosis, therapy and prevention of TURP syndrome.

Primary lymphoma of the epididymis: case report and review of the literature

Objective: To report an extremely rare clinical pathological observation of a case of primary lymphoma of the epididymis, without testicular or systemic involvement, and to update the relevant literature. Materials and Methods: A 25-year-old white male patient complaining of right scrotal pain was referred to our department. Clinical examination detected a hard painful mass at the right epididymal head. Epididymitis was diagonsed and conservative therapy with antibiotics and anti-inflammatory drugs was given. After 2 months of therapy the patient was admitted to our department because a tumor was suspected. Tumor markers were normal. Right scrotal exploration was performed through a standard inguinal incision. The epididymal head was completely replaced by a hard white mass. Fresh frozen sections indicated a malignant tumor. Right radical orchiectomy was performed. Results: High-grade primary epididymal non-Hodgkin’s lymphoma with diffuse large cells (group G according to the Working Fromulation) was diagnosed. Clinical pathological staging detected stage IE (extranodal) primary epididymal lymphoma. The patient was referred to the Hematologic Unit for combined chemotherapy, according to the VACOP-B protocol. After an 18-month follow-up the patient is well and disease free. Conclusions: When an epididymal mass does not benefit from medical treatment, scrotal exploration and fresh frozen sections of the lesion should be done. The possible bilateral involvement by primary epididymal lymphoma has to be kept in mind. Radical orchiectomy is the treatment of choice for primary lymphoma of the epididymis. Adjuvant chemotherapy is indicated in high-grade malignant lymphoma. Prognostic parameters of the disease may be the grade of malignancy and the size of the tumor.

Unilateral Laparoscopic Retroperitoneal Lymph Node Dissection for Clinical Stage I Nonseminomatous Germ Cell Testicular Neoplasm

Objective: The aim of this study is to evaluate the reliability of laparoscopic retroperitoneal lymph node dissection (LRPLND) in the management of clinical stage I nonseminomatous germ cell tumors (NSGCT). Methods: Since June 1993, unilateral LRPLND was performed in 6 patients diagnosed with clinical stage I NSGCT. All patients had undergone prior radical orchiectomy. The testicular cancer was left-sided in 3 cases and right-sided in the other 3 cases. Preoperative staging by means of tumor marker assessment, computerized tomography scan of the chest and abdomen and chest X-ray was unremarkable for metastatic disease. Results: All procedures were accomplished without any complications in a mean time of 325 min (275–420 min). The estimated perioperative blood loss was minimal (<50 ml), and none of the patients required blood transfusion. In the case of the first patient, the hospital stay was 18 days due to a widespread subcutaneous emphysema. In the remaining 5 cases, the average hospitalization was 4.8 days, ranging from 4 to 6 days. The patients resumed normal activities within 12–27 days (mean 16.16 days) postoperatively. The mean number of lymph nodes removed was 6.8, ranging from 5 to 9. Histologic examination of the dissected lymph nodes revealed microscopic metastases from embryonal carcinoma in 2 patients. Both of these patients received adjuvant chemotherapy. The mean follow-up period is 21.3 months, ranging from 6 to 36 months. To date, no relapses have been observed. Conclusion: In accordance with other reports, we believe that LRPLND is both feasible and effective. However, the definitive assessment of the efficacy and morbidity of this diagnostic procedure requires a larger and more comprehensive series as well as longer follow-up.

Considerations Regarding a Case of Leiomyoma of the Urinary Bladder

In spite of its rarity, leiomyoma of the bladder deserves to be better known as its diagnosis is not always obvious, depending as it does mainly on urography confirmed by anatomo-pathological examination, and particularly because its treatment is simple and the prognosis always favourable, a fact worthy of note in dealing with a tumour of the bladder.

Experience in the Surgical Treatment of Fraley’s Syndrome

Objective: To report our 20–year experience with nephron–sparing surgery in the treatment of Fraley’s syndrome.Materials and Methods: From September 1976 to July 1996, 6 women, 18–43 years old, underwent surgical treatment. All patients had been suffering debilitating right flank pain for at least 6 months before the operation. Diagnosis was in call cases made with the use of intravenous pyelography and renal arteriography, which showed a vascular impression on the superior infundibulum with secondary dilatation of the upper pole calyx. This was localized only on the right side in 5 cases, while in 1 it was bilateral though more severe on the right. Ipsilateral nephroptosis was observed in 2 of the patients. In 2 cases in whom the superior infundibulum was sufficiently long, an infundibulo–infundibulostomy with everted flaps was performed. In a case in whom a short infundibulum was compressed between a venous and an arterial branch, Fraley’s infundibulopyelostomy was carried out. In 1 patient in whom the infundibulum was compressed by the anterior–superior segmental artery, a Heineke–Mikulicz–type infundibulorrhaphy was combined to vasopexy. In the remaining 2 cases, the infundibulum was not cut: in one case, a simple vasopexy of two vascular branches was carried out, while in the other, a minor arterial branch was ligated and divided. In 4 patients, nephropexy was also performed.Results: No significant intra– or postoperative complications were observed. Follow–up averaged 102.5 months. Pain relief was complete in 5 cases, in whom disappearance of the vascular impression was also radiologically demonstrated. Only 1 patient, who underwent infundibulorrhaphy and vasopexy, experienced occasional flank pain and urinary infection after the operation, with just a slight improvement in the excretory urogram.Conclusions: Surgical treatment of Fraley’s syndrome is indicated only in symptomatic and/or complicated cases; in relation to the type of obstruction and the anatomy of the intrarenal structures, whether excretory or vascular, several effective nephron–sparing techniques can be selected.

Penetrating Trauma to the Scrotumand the Corpora cavernosa Caused by Gunshot

The authors describe a case of gunshot wound of the male genitalia by two low-velocity bullets. The first bullet caused a lesion of the right testicle and came out of the right hemiscrotum; the second one had penetrated the left gluteal region with no exit wound. The penile ultrasound confirmed the presence of the bullet at the root of the right corpus cavernosum. The patient underwent exploratory surgery, drainage of the voluminous bilateral scrotal hematoma, and suture of a laceration of the right-testicle cranial portion. Due to the absence of active bleeding, voluminous hematoma and serious injuries in the corpus cavernosum, no surgical removal of the bullet in the right corpus cavernosum was required. The patient regained a normal sexual function 1 month after the operation.

Argus-T Sling in 182 Male Patients: Short-term Results of a Multicenter Study

OBJECTIVE To evaluate the short-term results with Argus-T sling in patients with post-prostatectomy incontinence (PPI). MATERIALS AND METHODS A total of 182 patients with PPI were treated with Argus-T sling at 5 urologic centers from June 2008 to March 2013. The preoperative evaluation included medical history, pad count (1-2 pads: mild PPI; 3-5 pads: moderate PPI; >5 pads: severe PPI), visual analog scale on continence, quality of life score scale, physical examination, cystoscopy, and urodynamic evaluation. Postoperative evaluation was performed 6 weeks postoperatively, and late follow-up was achieved in April 2013. We considered a successful result when patients were cured (0-1 pads/24 hours) and or improved (1-2 pads/24 hours or a reduction in pad per day usage greater than 50%). RESULTS Twenty-one (11.8%), 96 (52.7%), and 65 (35.7%) patients have mild, moderate, and severe incontinence, respectively. At the median follow-up of 22 months, the overall success rate was 86.2%. We obtained successful results of 95% in mild incontinence, 78% in moderate incontinence and 70% in severe incontinence. In cured and improved patients, we observed a statistically significant amelioration of quality of life (P <.0001). Sling regulation was carried out in 42.9% of cases, whereas its removal occurred in 9.3% of cases. Postoperative complications were reported in 14.3% of patients. In patients with previous radiotherapy, we observed a successful result in 61.2% of cases. CONCLUSION This study represents the first report that shows short-term results of Argus-T positioning in a large population. Argus-T seems to offer good outcomes in patients with mild and moderate PPI.

Notice of Duplicate Publication

Upon close scrutiny of Figure 2 in the article by Webley and coworkers published in AJRCCM (1) and Figure 2 from the article by Cirino and coworkers published in BMC Infectious Diseases (2), we realized that the figure in BMC Infectious Diseases was a lower magnification of part of the same field as that used in the AJRCCM article. These figures both describe the growth of Chlamydia from clinical samples on the same tissue culture substrate (J774A.1 cells) and were in a single database of figures with different numeric designations. The experiments that led to the data for these two articles were generated around the same time and were compiled and stored in the same folder since pictures are taken in bulk at our microscopy facility where we pay a fee for the microscopy services. We believe that sometime during the compilation and annotation process, Figure 2 in the BMC Infectious Diseases article was incorrectly labeled as being generated from the normal donor project and was later used in that manuscript. In fact, this figure was taken from a culture coverslip that was infected with lysates from pediatric bronchial lavage samples. The AJRCCM figure was a 600 immunofluorescence image of a field on a coverslip, part of which can be seen in the lower magnification image (400 ) in the BMC Infectious Diseases article. The authors will supply the editor ofBMC Infectious Diseases with the appropriate representative culture image from normal donor infection of J774A.1 cells to replace the existing one. We deeply regret this error in image annotation and later image selection and hope that this will in no way detract from the important data contained in these two manuscripts.
