Long-term urinary dysfunction after mesorectal excision: a prospective study with intraoperative electrophysiological confirmation of nerve preservat…
2006
Bladder dysfunctions are well-recognized complications after nerve-sparing mesorectal excision for rectal cancer. This study sought to symptomatically analyze the extent of recovery from major and minor urinary symptoms in patients with signs of bladder denervation.Sixty-two patients with mesorectal excision for rectal cancer were investigated prospectively. Pelvic autonomic nerve preservation (PANP) was assessed macroscopically and with the aid of intraoperative electrical stimulation of pelvic autonomic nerves (INS). Bladder function was evaluated with the International Prostate Symptom Score (IPSS) and the Quality of life index (Qol). Median follow-up was 20 months (range 3-40 months).Fo…
Transposition of the left renal vein for treatment of the nutcracker phenomenon: long-term follow-up
2002
Abstract Objectives To assess the therapeutic value of left renal vein transposition for treatment of the nutcracker phenomenon in long-term follow-up. Methods Eight patients (4 women and 4 men) between 23 and 58 years old (mean 39.1) underwent transposition of the left renal vein for treatment of the nutcracker phenomenon associated with recurrent gross hematuria and flank pain. The postoperative follow-up was 41 to 136 months (mean 66.4). Results No perioperative complications were encountered. The postoperative complications comprised deep vein thrombosis (n = 1), retroperitoneal hematoma necessitating surgical revision (n = 1), and paralytic ileus that resolved with conservative managem…
Treatment of idiopathic oligozoospermia with tamoxifen--a randomized controlled study.
1992
There is no conclusive evidence of the usefulness of tamoxifen in the treatment of idiopathic oligozoospermia (OAT-syndrome), as it has been used mostly in uncontrolled studies. We herein report on the controlled treatment of OAT-syndrome with tamoxifen versus placebo following a randomized design. Seventy-six men with sperm counts of 2-20 x 10(6) ml-1, sperm motility of 20-50%, and sperm morphology (abnormal cells) between 50 and 80% were involved in the study. Patients with varicocele, a history of testicular maldescent or genital inflammation were excluded. Thirty-nine patients received tamoxifen (30 mg daily), 37 patients placebo. There was a statistically significant increase in the me…
Nephron-sparing surgery of renal cell carcinoma with a normal opposite kidney: long-term outcome in 180 patients
2000
Abstract Objectives. To investigate the long-term outcome of an organ-saving approach for renal cell carcinoma (RCC) with a normal opposite kidney (elective indication). Methods. Since 1979, 180 patients have undergone nephron-sparing surgery at our institution for RCC in the presence of a normal contralateral kidney. The mean age was 56 years (range 23 to 83), and the mean follow-up was 4.7 years (maximum 14.8). Most of these tumors were found incidentally, with a mean tumor diameter on ultrasound of 3.3 cm (range 1.0 to 8.6). Results. The postoperative course was unremarkable in 173 patients. Postoperative bleeding was encountered in 4 patients and urinary extravasation in an additional 3…
Conservative surgery of renal cell tumors in 140 patients: 21 years of experience.
1992
Operative method, course and complications were analyzed retrospectively in 140 patients who underwent a conservative operation for renal tumor between June 1969 and December 1990. In 53 patients (20 women and 33 men, mean age 61.2 years, range 38 to 77 years, with 49 renal cell carcinomas and 4 benign renal tumors) there was an imperative indication for an organ preserving operation because nephrectomy would have made dialysis obligatory. In 87 patients (29 women and 58 men, mean age 53.7 years, range 27 to 74 years, with 72 renal cell carcinomas and 15 benign renal tumors) the tumor was conservatively resected in the presence of a normal contralateral unit (elective indication) and 68 of …
Radical cystectomy with or without adjuvant polychemotherapy for non-organ-confined transitional cell carcinoma of the urinary bladder: prognostic im…
1996
To analyze the effectiveness of adjuvant polychemotherapy after radical cystectomy for non-organ-confined transitional cell bladder cancer (Stages pT3b, pT4a, and/or pN1 or pN2).Of 166 consecutive patients undergoing cystectomy at two institutions from 1987 to 1993, 80 received adjuvant polychemotherapy with methotrexate, vinblastine, and cisplatin plus doxorubicin (MVAC) or epirubicin (MVEC), whereas 86 had cystectomy only. The patients were evaluated for relapse-free survival and length of progression-free interval on the basis of follow-up data obtained in 1995 and 1996.Kaplan-Meier analysis revealed a significantly higher progression-free rate for patients after adjuvant chemotherapy (P…
The Mainz pouch II (sigma rectum pouch).
1993
A low pressure rectosigmoid reservoir for urine is created obviating the need for colostomy, augmentation or extensive bowel surgery. Antimesenteric splitting of the intestine at the rectosigmoid junction and subsequent side-to-side anastomosis are performed. Urodynamic data demonstrate that the detubularization is effective in rendering high pressure bowel contractions ineffective. Without the risk of damaging the mesentery the pouch is fixed at the promontory, which lessens the risk of ureteral kinking and upper urinary tract dilatation. The technique is indicated not only in cases of failed ureterosigmoidostomy but also for primary urinary diversion. All 47 patients who underwent the ope…
NEPHRON SPARING SURGERY FOR CENTRAL RENAL TUMORS: EXPERIENCE WITH 33 CASES
2000
Purpose: Nephron sparing surgery is standard treatment for small, peripherally located renal cell carcinoma. In patients with a solitary kidney, bilateral tumors or impaired renal function nephron sparing surgery provides the only option to nephrectomy and subsequent hemodialysis or transplantation. We retrospectively investigated the value of nephron sparing surgery for centrally located renal cell carcinoma. Materials and Methods: Between 1969 and 1997, 311 renal tumor enucleations were performed at our institution. The tumor was centrally located in 33 cases. The indication for enucleation was elective in 7 cases and imperative in 26, including bilateral tumor in 16 (metachronous in 9 an…
Microcirculation in the healing of surgical wounds in the oral cavity.
2013
Abstract. The aim of this research is to evaluate in vivo the characteristics of microcirculation after taking a biopsy sample from the oral mucosa. 20 patients were recruited to the study and all underwent an oral mucosa biopsy for the excision of benign neoformations. The modifications in the oral microcirculation were evaluated in vivo in correspondence to the surgical site through videocapillaroscopy at three different times: 30 min before the biopsy; 48 h after the biopsy; and 7 days after the biopsy. The statistical significance was checked with the Mann–Whitney U-test (P < 0.05). The analysis of videocapillaroscopic patterns showed statistically significant variations relative to the…
Incomplete Conventional Colonoscopy: Magnetic Resonance Colonography in the Evaluation of the Proximal Colon
2005
Background and Study Aims: The purpose of this study was to evaluate dark-lumen magnetic resonance (MR) colonography prospectively in patients with incomplete conventional colonoscopy. Patients and Methods: Thirty-two patients with incomplete conventional colonoscopy underwent same-day dark-lumen MR colonography on the basis of a standard protocol. The depiction of colorectal diseases was assessed in the following colon segments: cecum, ascending colon, transverse colon, descending colon, sigmoid colon, and rectum. The reasons for incomplete colonoscopy included high-grade stenosis in 26 patients (four with occlusive cancer, 12 with fibrotic stenosis based on recurrent sigmoid diverticuliti…
