ABSTRACT

PURPOSE: Penile carcinoma is a rare but mutilating malignancy. In this context, partial penectomy is the most commonly applied approach for best oncological results. We herein propose a simple modification of the classic technique of partial penectomy, for better cosmetic and functional results. TECHNIQUE: If partial penectomy is indicated, the present technique can bring additional benefits. Different from classical technique, the urethra is spatulated only ventrally. An inverted "V" skin flap with 0.5 cm of extension is sectioned ventrally. The suture is performed with vicryl 4-0 in a "parachute" fashion, beginning from the ventral portion of the urethra and the "V" flap, followed by the "V" flap angles and than by the dorsal portion of the penis. After completion of the suture, a Foley catheter and light dressing are placed for 24 hours. CONCLUSIONS: Several complex reconstructive techniques have been previously proposed, but normally require specific surgical abilities, adequate patient selection and staged procedures. We believe that these reconstructive techniques are very useful in some specific subsets of patients. However, the technique herein proposed is a simple alternative that can be applied to all men after a partial penectomy, and takes the same amount of time as that in the classic technique. In conclusion, the "parachute" technique for penile reconstruction after partial amputation not only improves the appearance of the penis, but also maintains an adequate function.

ABSTRACT

Introduction: Two positions have been reported for ureteroscopy (URS): dorsal lithotomy (DL) position and dorsal lithotomy position with same side leg slightly extended (DLEL). The aim of the present study was to compare the outcomes associated with URS performed with patients in DL vs. DLEL position. Material and Methods: A total of 98 patients treated for ureteral calculi were randomized to either DL or DLEL position during URS, and were prospectively followed. Patients, stone characteristics and operative outcomes were evaluated. Results: Of the 98 patients included in the study, 56.1 percent were men and 43.9 percent women with a mean age of 42.6 ± 16.8 years. Forty-eight patients underwent URS in DL position and 50 in DLEL position. Patients' age, mean stone size and location were similar between both groups. Operative time was longer for the DL vs. DLEL group (81.0 vs. 62.0 minutes, p = 0.045), mainly for men (95.2 vs. 63.9 minutes, p = 0.023). Mean fluoroscopy use, complications and success rates were similar between both groups. Conclusions: Most factors associated with operative outcomes during URS are inherent to patient's condition or devices available at each center, and therefore cannot be changed. However, leg position is a simple factor that can easily be changed, and directly affects operative time during URS. Even though success and complication rates are not related to position, placing the patient in dorsal lithotomy position with an extended leg seems to make the surgery easier and faster.

ABSTRACT

OBJECTIVE: No consensus has yet been established regarding the best minimally invasive access for radical ablation of renal tumors. Our objective was to prospectively compare the surgical results and oncologic management of two currently used endoscopic techniques. MATERIAL AND METHODS: Over a four-year period, 50 patients with renal tumors and clinical stage T1b-T2, smaller than 12 cm, underwent a radical nephrectomy at two reference institutions, 25 underwent retroperitoneoscopic radical nephrectomy (RRN) and 25 a hand-assisted laparoscopic radical nephrectomy (HALRN). Mean follow-up of both cohorts was 50 months. Operative parameters and oncological management were compared. RESULTS: The mean operative time was 180 min in RRN and 108 min in HALRN (p < 0.001). The time required to access the renal pedicle in RRN was 30 min. and in HALRN 40 min., Learning curve was shorter in HALRN than RRN. Mean blood loss was 100 mL in RRN and 242 mL in HALRN. Mean incision size for specimen retrieval in RRN was 6.5 cm and in HALRN 7.5 cm. One patient with intra operative occurrence of ascites and subsequent pathological stage pT2N0M0 grade 3 operated via HALRN, had neoplasic implants in the Hand-port incision 3 months after surgery followed by death 4 months after recurrence. One patient, with pathological stage pT3N0M0 grade 3 in RRN had metastasis after 36 months. CONCLUSION: Both, RRN and HALRN techniques are accepted minimally invasive options for endoscopic radical nephrectomy with equivalent long term oncological outcome in the treatment of renal tumors.

ABSTRACT

OBJECTIVES: Describe and illustrate a new minimally invasive approach for the radical resection of inguinal lymph nodes. SURGICAL TECHNIQUE: From the experience acquired in 7 operated cases, the video endoscopic inguinal lymphadenectomy (VEIL) technique was standardized in the following surgical steps: 1) Positioning of the inferior member extended in abduction, 2) Introduction of 3 work ports distal to the femoral triangle, 3) Expansion of the working space with gas, 4) Retrograde separation of the skin flap with a harmonic scalpel, 5) Identification and dissection of the long saphenous vein until the oval fossa, 6) Identification of the femoral artery, 7) Distal ligature of the lymph node block at the femoral triangle vertex, 8) Liberation of the lymph node tissue up to the great vessels above the femoral floor, 9) Distal ligature of the long saphenous vein, 10) Control of the saphenofemoral junction, 11) Final liberation of the surgical specimen and endoscopic view showing that all the tissue of the region was resected, 12) Removal of the surgical specimen through the initial orifice, 13) Vacuum drainage and synthesis of the incisions. COMMENTS: The VEIL technique is feasible and allows the radical removal of inguinal lymph nodes in the same limits of conventional surgery dissection. The main anatomic repairs of open surgery can be identified by the endoscopic view, confirming the complete removal of the lymphatic tissue within the pre-established limits. Preliminary results suggest that this technique can potentially reduce surgical morbidity. Oncologic follow-up is yet premature to demonstrate equivalence on the oncologic point of view.

ABSTRACT

PURPOSE: To make an objective controlled comparison of pain tolerance in transrectal ultrasound-guided prostatic biopsy using intrarectal topic anesthesia, injectable periprostatic anesthesia, or low-dose intravenous sedation. MATERIALS AND METHODS: One hundred and sixty patients were randomized into 4 groups: group I, intrarectal application of 2 percent lidocaine gel; group II, periprostatic anesthesia; group III, intravenous injection of midazolam and meperidine; and group IV, control, patients to whom no sedation or analgesic was given. Pain was evaluated using an analogue pain scale graded from 0 to 5. Acceptance of a repetition biopsy, the side effects of the drugs and complications were also evaluated. RESULTS: 18/20 (90 percent) and 6/20 (30 percent) patients reported strong or unbearable pain in the group submitted to conventional biopsy and topical anesthesia (p = 0.23, chi-square = 1.41); whereas those submitted to periprostatic blockade and sedation, severe pain occurred in only 2/60 (3 percent) patients (p < 0.001, chi-square = 40.19) and 3/60 (5 percent) patients (p < 0.001, chi-square = 33.34). Acceptance of repetition of the biopsy was present in only 45 percent of the patients submitted to conventional biopsy, 60 percent of those that were given topical anesthesia (p = 0.52, chi-square = 0.4), compared to 100 percent of those submitted to periprostatic anesthesia (p < 0.01, chi-square = 15.17), and 95 percent of those who were sedated (p < 0.001, chi-square = 25.97 percent). CONCLUSIONS: Transrectal ultrasound-guided prostatic biopsy is an uncomfortable experience; however application of periprostatic blockade and intravenous analgesia are associated to higher tolerance of the exam and patient comfort. Low dose sedation by association of intravenous meperidine and midazolam is an emerging and safe outpatient option.

ABSTRACT

INTRODUCTION: We describe our experience with hand-assisted laparoscopy (HAL) as an option for the treatment of large renal specimens. MATERIALS AND METHODS: Between March 2000 and August 2004, 13 patients candidate to nephrectomies due to benign renal conditions with kidneys larger than 20 cm were included in a prospective protocol. Unilateral nephrectomy was performed in cases of hydronephrosis (6 patients) or giant pyonephrosis (4 patients). Bilateral nephrectomy was performed in 3 patients with adult polycystic kidney disease (APKD) with low back pain refractory to clinical treatment previous to kidney transplant. The technique included the introduction of 2 to 3 10 mm ports, manual incision to allow enough space for the surgeon's wrist without a commercial device to keep the pneumoperitoneum. The kidney was empty, preferably extracorporeally, enough to be removed through manual incision. We have assessed operative times, transfusions, complications, conversions, hospital stay and convalescence. RESULTS: The patients mean age (9 women and 4 men) was 58 years. Mean operating time was 120 n 10 min (hydronephrosis), 160 n 28 min (pyonephrosis) and 190 n 13 min (bilateral surgery for APKD). There was a need for a conversion in 1 case and another patient needed a transfusion due to a lesion in the renal vein; 2 patients had minor complications. CONCLUSION: HAL surgery is a minimally invasive alternative in the treatment of large renal specimens, with or without significant inflammation.

ABSTRACT

OBJECTIVE: To present results obtained with laparoscopic correction of incisional lumbar hernia in patients with minimum follow-up of 1 year. MATERIALS AND METHODS: We prospectively studied 7 patients diagnosed with incisional lumbar hernia after physical examination and computerized tomography. We used laparoscopic transperitoneal access through 3 ports. One polypropylene mesh was introduced in the abdominal cavity and fixed by titanium clamps to the margins of the hernia ring following release of the peritoneum. RESULTS: All cases were successfully completed with no conversion required. Mean surgical time was 120 minutes and discharge from hospital occurred between the 1st and the 2nd postoperative days. There were no intraoperative complications or hernia recurrence in any case. Postoperatively, we had 2 minor complications: one case of seroma that resolved spontaneously after 60 days and one patient presenting lumbar pain that persisted until the 3rd postoperative month. The return to usual activities occurred on average 3 weeks following intervention. Of the 7 patients, 6 were satisfied with the esthetical and functional effect produced by the procedure. CONCLUSIONS: The surgical correction of incisional lumbar hernia by laparoscopic access is an excellent option for a minimally invasive treatment, with adequate long-term results.

ABSTRACT

OBJECTIVE: To describe surgical and functional results with extraperitoneal laparoscopic radical prostatectomy with duplication of the open technique, from the experience obtained in the treatment of 28 initial cases. MATERIALS AND METHODS: In a 36-month period, we prospectively analyzed 28 patients diagnosed with localized prostate cancer undergoing extraperitoneal laparoscopic radical prostatectomy. RESULTS: Mean surgical time was 280 min, with mean blood loss of 320 mL. As intraoperative complications, there were 2 rectal lesions repaired with laparoscopic suture in 2 planes. There was no conversion to open surgery. Median hospital stay was 3 days, with return to oral diet in the first post-operative day in patients. As post-operative complications, there were 3 cases of extraperitoneal urinary fistula. Two of these cases were resolved by maintaining a Foley catheter for 21 days, and the other one by late endoscopic reintervention for repositioning the catheter. Five out of 18 previously potent patients evolved with erectile dysfunction. The diagnosis of prostate cancer was confirmed in all patients, with focal positive margin occurring in 3 cases. During a mean follow-up of 18 months, 2 patients presented increased PSA, with no clinical evidence of disease. CONCLUSION: Laparoscopic radical prostatectomy is a laborious and difficult procedure, with a long learning curve. Extraperitoneal access is feasible, and it is possible to practically duplicate the principles of open surgery. The present technique can possibly offer advantages in terms of decreased blood loss, preservation of erectile function and prevention of positive margins.

ABSTRACT

We present a case of retrocaval ureter featuring laparoscopic technique treatment using extraperitoneal access and extracorporeal suture of the ureteral stumps. Surgical time was 130 minutes, and the anastomosis was performed in 40 minutes. There were no intra- or postoperative complications, and the patient was discharged from hospital on the second postoperative day. The medium-term outcome featured similar results to pure laparoscopic technique. We conclude that this technical variation for treatment of retrocaval ureter makes the procedure easier and provides a drastic reduction in surgical time, without compromising the minimally invasive aspect of this kind of approach.

ABSTRACT

INTRODUCTION: The present study shows and discusses the preliminary experience of customized and staged approach in the minimally invasive treatment of inflammatory renal diseases, using either pure laparoscopic surgery or the hand-assisted technique. MATERIALS AND METHODS: We prospectively assessed 17 patients with inflammatory renal diseases operated by laparoscopic approach. Mean age was 41 years and the surgical indication was repeated pyelonephritis in 8 cases, pyonephrosis in 4 cases and renal exclusion due to staghorn stone in 5 cases. The staged laparoscopic approach was chosen based on kidney size and on the presence or not of tomographic findings showing significant perirenal infiltration. Thus, retroperitoneal access was chosen in cases where the kidney was smaller than 12 cm or in the absence of signs of significant perirenal infiltration on the computerized tomography. For the remainder, transperitoneal access was employed. RESULTS: Of the 17 patients, 11 underwent laparoscopic nephrectomy by retroperitoneal access, and all cases were successful. Mean surgical time was 160 minutes. In 6 cases where the nephrectomy was performed by laparoscopic transperitoneal access, the use of hand assistance was required. Four surgeries were successfully completed with mean time of 190 minutes and 2 were converted to open surgery with mean time of 220 minutes. CONCLUSION: The laparoscopic nephrectomy for inflammatory renal disease is feasible, but presents a high degree of complexity, requiring a customized approach. The use of hand assistance is an attractive option when the inflammatory process is intense, and can avoid conversions, maintaining the advantages of minimally invasive treatments.

ABSTRACT

OBJECTIVE: The present study aims to report the preliminary experience with videolaparoscopic retroperitoneal lymphadenectomy in the treatment of patients with non-siinomatous testicular tumor. MATERIALS AND METHODS: Seven surgeries were performed in order to access retroperitoneal lymph nodes in patients with non-siinomatous testicular cancer. We performed the videolaparoscopic retroperitoneal lymphadenectomy (LRL) technique in 5 patients with stage I disease and laparoscopic resection of residual mass (LRRM), following chiotherapy (ChT), in 2 patients with stage II disease. Initial approach was obtained through 4 trocars, using an incision in supra-umbilical midline when manual assistance was required. Surgical time was analyzed, as well as blood loss, need for analgesic drugs postoperatively, hospital stay, complications, need for blood transfusion, histopathological data and tumor control in a mean follow-up of 18 months. RESULTS: Mean surgical time was 200 to 260 minutes in LRL and LRRM groups respectively, mean blood loss was 300 mL for the LRL group and 400 mL for the LRRM group, without need for transfusions. There was a lesion in the vena cava in the LRL group, which was managed with manual assistance and one conversion in the LRRM group, due to a 10-cm tumor mass that was adhered to the aorta. Mean hospital stay was 3 days, excluding the converted case, and the use of analgesic drugs was needed until the second postoperative day. Of the stage I patients, 2 had active disease in retroperitoneum, and underwent adjuvant ChT. The 2 residual masses were teratomas. There was no recurrence during the follow-up period. CONCLUSIONS: Videolaparoscopic retroperitoneal lymphadenectomy is a procedure with high technical complexity and a higher potential for conversion when performed following chiotherapy.

ABSTRACT

INTRODUCTION: The laparoscopic radical prostatectomy is a continually developing technique. Transperitoneal access has been preferred by the majority of centers that employ this technique. Endoscopic extraperitoneal access is used by a few groups, nevertheless it is currently receiving a higher acceptance. In general, the antegrade technique is used, with dissection from the bladder neck to the prostate apex. The objective of the present paper is to describe the extraperitoneal technique with reproduction of the open surgery's surgical steps. SURGICAL TECHNIQUE: With this technique, the dissection of the prostate apex is performed and, following the section of the urethra while preserving the sphincteric apparatus, the Foley catheter is externally tied and internally recovered, which allows cranial traction, similarly to the way it is performed in conventional surgery. The retroprostatic space is posteriorly dissected and the seminal vesicles are identified by anterior and posterior approach, obtaining with this method an optimal exposure of the posterolateral pedicles and the prostate contour. The initial impression is that this technique does not present higher bleeding rate or difficulty level when compared with antegrade surgery. Potential advantages of this technique would be the greater familiarity with surgical steps, isolated extraperitoneal drainage of urine and secretions and a good definition of prostate limits and lateral pedicles, which are critical factors for preserving the neurovascular bundles and avoiding positive surgical margins. A higher number of cases and a long-term follow-up will demonstrate its actual value as a technical option for endoscopic access to the prostate.

ABSTRACT

INTRODUCTION: Surgery represents the main therapeutic modality for stress urinary incontinence. In incontinent patients with urethral hypermobility, the retropubic colposuspension by Burch technique is one of the surgeries that present better long-term results. Current trends towards performing minimally invasive techniques led proposing the Burch surgery through videolaparoscopy. The laparoscopic technique's long-term efficacy is a highly controversial issue. However, even if late results turn out to be satisfactory, the assumed advantages of laparoscopy (faster recovery, less pain, early return to daily activities, etc.) must be evident, in order to justify the use of this minimally invasive surgical access. MATERIALS AND METHODS: We reviewed our records and analyzed the medical charts of 26 female patients who underwent Burch surgery by open approach and 36 female patients by laparoscopic approach, between May 1999 and February 2001. The satisfaction level, surgical complication rates, surgery length, hospital stay and return to daily activities were analyzed. RESULTS: Mean age was 42 years, ranging from 27 to 68 years. Epidemiological data from both groups were not statistically different. Patients operated by laparoscopic route had a shorter hospital stay (p = 0.002) and a faster return to their daily activities (p < 0.001). However, there were no statistical differences in the following parameters: surgical time (p = 0.11), surgical complications (p = 0.98), patient satisfaction immediately (p = 0.77) and 90 days following surgery (p = 0.84), surgery acceptance (p = 0.85), indication of this surgery to a friend (p = 0.93) and score given to the procedure (p = 0.68). CONCLUSIONS: Even if the efficacy of both methods is similar, we did not observe significant advantages of laparoscopic surgery over open surgery, concerning the recovery in recent post-operative period.

ABSTRACT

Laparoscopic surgery in urology is definitely incorporated to the techniques of minimally invasive treatment for urogenital diseases. Though the classic access to organs in the urinary tract is extraperitoneal, this access has not been prioritized when the videoendoscopic technique is used. In Brazil, few groups use this approach and little has been discussed about its true practical applicability. The authors intended to discuss the main technical aspects and criteria for indication, reported though the improvement achieved in a 5-year period with 150 operated cases. A review of the literature shows that the worldly acceptance of the extraperitoneal endoscopic approach is increasing. Nevertheless, there are no evidences that the extraperitoneal access is superior to the transperitoneal route. Thus, the choice depends basically on the surgeon's preference. Major advantages are the immediate access to the renal hilum and isolation of peritoneal structures. Employing this access is useful when one suspects that significant peritoneal adherences could prevent the surgical act or when one wishes to preserve the integrity of the peritoneal cavity.

ABSTRACT

OBJECTIVE: To compare, prospectively, 4 different schemes of antibiotic prophylaxis previously to transrectal prostate biopsy. MATERIALS AND METHODS: 257 patients were randomized in 4 groups: Group I: single dose of ciprofloxacin 2 hours before the procedure; Group II: ciprofloxacin 3 days; Group III: chloramphenicol 3 days; and Group IV: norfloxacin 3 days. The complication rate was assessed in a blind way on the third and on the thirtieth days through a questionnaire. Groups were compared by the qui-square method and, in small samples, by the Fisher method, with statistical significance of 95 percent. RESULTS: Complications index throughout the sample differed between the 4 groups of patients under study, being 3.1 percent for group I, 2.1 percent for group II, 18.3 percent for group III and 10.5 percent for group IV. Schemes employing ciprofloxacin were statistically superior to those that used norfloxacin or chloramphenicol (p < 0.05). There was no difference between a single dose and 3 days of ciprofloxacin (p > 0.05). CONCLUSION: Schemes using ciprofloxacin presented better results in prophylaxis previously to prostate biopsy. We recommend using a single dose of ciprofloxacin due to its posologic ease and low cost, associated with a therapeutic response equivalent to 3-day regimens.

ABSTRACT

Objetivo: Mostrar as vantagens e dificuldades no acesso ao retroperitônio para realização de biopsia renal laparoscópica. Material e métodos: Foram analisados 30 pacientes que não tinham indicação para a realização de biópsia pela via percutânea (coagulopatia,alteração anatômica e falha no procedimento percutâneo), submetidos a biópsia renal pela via laparoscópica. O acesso foi realizado através de incisão na extremidade da 12a. costela e dissecção da musculatura até o retroperitônio. Após este procedimento, o balão de Gaur modificado era locado no retroperitônio e insuflado com 500 a 800 ml de soro fisiológico. A biopsia era realizada com 1 ou 2 portais adicionais de 5mm. Resultado: As dificuldades encontradas na retroperitoneoscopia foi o pequeno espaço de trabalho, algumas vezes com dificuldade de manipulação dos instrumentos laparoscópicos. Ocorreu conversão em apenas um paciente, devido a problemas de visualização do rim. Observou-se a ruptura do balão em 2 casos, sem lesões adicionais. Perfuração no peritônio ocorreu em 3 casos, sem necessidade de conversão. O tempo médio do procedimento foi de 40 minutos. Conclusão: A retroperitoneoscopia para biópsia renal é um procedimento com baixo índice de complicações. As vantagens são o fácil acesso ao rim e a retirada adequada de material para análise. A principal desvantagem é o pequeno espaço de trabalho.

ABSTRACT

Objetivos: Estudamos pacientes submetidos à biópsia de próstata com 12 fragmentos (Bx12F) com o objetivo de avaliar sua sensibilidade no diagnóstico do câncer de próstata (CaP), bem como o acréscimo de informações patológicas nos portadores de CaP quando comparadas às obtidas com a biópsia de próstata em sextante (Bx6F) guiada por ultra-sonografia transretal. Materiais e métodos: Setenta e oito homens foram submetidos à Bx12F. A ultra-sonografia transretal obteve o volume prostático e dirigiu as biópsias nas 12 seguintes regiões: ápice direito e esquerdo, médio direito e esquerdo, base direita e esquerda, zona de transição direita e esquerda, médio-lateral direito 1 e 2, e médio-lateral esquerdo 1 e 2. A eficiência da Bx12F foi comparada aos 6 fragmentos da Bx6F dos mesmos pacientes. Resultados: A média do PSA foi de 17,3 ng/ml, e 60 pacientes (77 porcento) possuíam toque retal alterado. A Bx12F diagnosticou 28 CaP (35 porcento), acrescentando 2 (8 porcento) tumores (p=0,81) e 2 (50 porcento) casos de neoplasia intra-epitelial prostática (NIP) aos fragmentos da Bx6F. Nos 6 portadores de CaP cujas próstatas superavam 40g, a Bx12F adicionou 2 tumores aos 4 diagnosticados pela Bx6F, enquanto que nos 22 portadores de CaP com próstatas menores de 40g, Bx12F não acrescentou nenhuma neoplasia (p=0,039). Nos casos de CaP, os fragmentos adicionais aumentaram o percentual de fragmentos comprometidos em 4 casos, diagnosticaram CaP bilateral em 1 caso, aumentaram o escore de Gleason em 1 caso, e acrescentaram 2 casos de infiltração perineural. Conclusões: A Bx12F não aumenta a sensibilidade diagnóstica de CaP em relação à Bx12F entre pacientes com PSA elevado e nódulo palpável. No subgrupo de pacientes com próstatas maiores que 40g, a Bx12F aumenta o número de CaP diagnosticados.

ABSTRACT

Objetivo: o acometimento do trato urinário pela endometriose é raro e quando ocorre, a bexiga é o órgão mais freqüentemente afetado. Observamos que algumas pacientes tem sido encaminhadas com o diagnóstico clínico de neoplasia vesical. Em geral, a literatura mostra relatos isolados de casos, tornando difícil a padronização de condutas. Tivemos por objetivo apresentar nossa experiência, mostrando os principais aspectos diagnósticos e terapêuticos desta entidade clínica. Métodos: avaliamos retrospectivamente os casos com diagnóstico de endometriose vesical por meio do arquivo do Departamento de Patologia, fazendo revisão dos dados clínicos de prontuário e convocando as pacientes para seguimento ambulatorial após tratamento. Resultados: os principais sinais e sintomas apresentados pelas pacientes foram disúria cíclica, massa e dor pélvica crônica. O diagnóstico presuntivo foi realizado mediante ultra-sonografia (USG), tomografia computadorizada (TC) de abdome, cistoscopia a laparoscopia. O diagnóstico definitivo com confirmação anátomo-patológica foi obtido pela ressecção endoscópica em 3 casos e biópsia laparoscópica em 1 caso. As opções terapêuticas foram o tratamento medicamentoso exclusivo e a ressecção da lesão empregando a via endoscópica ou cistectomia parcial, sempre complementados por tratamento clínico adjuvante. Conclusões: revisamos os principais aspectos clínicos e terapêuticos da endometriose do trato urinário, lembrando que esta representa um importante diagnóstico diferencial de tumor vesical em mulheres jovens na idade reprodutiva

ABSTRACT

Cancer of the uterine cervix has been related to HPV infection, based on clinical and laboratory data. The high recurrence rate in couples undergoing treatment for HPV infection points to a probable viral reservoir, either in subclinical lesions or in male internal genital organs. We have evaluated 31 men, all sexual partners of women with HPV infection. Eleven patients (35.5%) had related lesions: 4 (12.9%) with condyloma acuminatum; 5(16.1%) with lesions revealed by magnified examination after reaction with 5% acetic acid and 2(6.5%) with condyloma and subclinical lesions. A short-term follow-up confirmed a successful treatment with podophyllin
